Shaping the Land: Geology and Geography of California
Level 4
IDEA PAGES
I UNIT THEME – Geology affects the Geography of California and the World, and the formation of the earth is a dynamic, ever evolving process. Climate Change is accelerating this process.
• Powerful forces have shaped the earth, and continue to transform the land where we live.
• Climate Change is accelerating the rate which our land transforms through these natural processes.
• Cross Cultural Theme
• Different cultures have stories and legends that explain natural phenomena and answer questions about how Earth was created and changes.
• Living things in California and around the world are affected by climate change. Working together, we can help save our planet.

V. CALIFORNIA SCIENCE STANDARDS – Grade 4
EARTH SCIENCE
4.0 The properties of rocks and minerals reflect the processes that formed them. As a basis for understanding this concept:
a. Students know how to differentiate among igneous, sedimentary, and metamorphic rocks by referring to their properties and methods of formation (the rock cycle) (Exposed to this concept, not the focus).
5.0 Waves, wind, water, and ice shape and reshape Earth's land surface. As a basis for understanding this concept:
a. Students know some changes in the earth are due to slow processes, such as erosion, and some changes are due to rapid processes, such as landslides, volcanic eruptions, and earthquakes.
b. Students know natural processes, including freezing and thawing and the growth of roots, cause rocks to break down into smaller pieces.
c. Students know moving water erodes landforms, reshaping the land by taking it away from some places and
depositing it as pebbles, sand, silt, and mud in other places (weathering, transport, and deposition).
IDEA PAGES 2
Investigation and Experimentation
6.0 Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept and addressing the content in the other three strands, students should develop their own questions and perform investigations.
a. Differentiate observation from inference (interpretation) and know scientists' explanations come partly from what they observe and partly from how they interpret their observations.
c. Formulate and justify predictions based on cause-and-effect relationships.
f. Follow a set of written instructions for a scientific investigation.

Have you Heard About the Earth?
1 By: Sera Hernandez
Have you heard about the earth? Water, wind, and ice shape and reshape its surface.
Our planet Earth has been around for about 4.6 billion years. In that time, it has dramatically changed from a mass of rocks, to a planet with majestic mountains, golden valleys, endless rivers, and massive oceans. In fact, the Earth’s surface is constantly changing through a variety of slow and fast processes.
Have you heard about the earth? Water, wind, and ice shape and reshape its surface.
Earth’s surface is covered by a layer of rock called the crust. Beneath the crust is the mantle, the thickest layer of the earth. The mantle is so fiery hot that it actually melts rocks. The heat changes the rocks into a thick, heavy liquid called magma. Underneath the mantle is the earth’s core, which is composed of solid rock.
Have you heard about the earth? Water, wind, and ice shape and reshape its surface.
Earth’s crust is made up of 30 huge rocks, called tectonic plates, which fit together like a jigsaw puzzle. These plates have been moving for millions of years and still drift today.
Geologists divide the rocks that make up the Earth’s crust into three groups: igneous, sedimentary, and metamorphic rock. These rocks all come from the same original material, which moves around in a big cycle.
Have you heard about the earth? Water, wind, and ice shape and reshape its surface.
There are natural processes that cause rocks to change size and shape. When air, wind, ice, or plants change the shapes of rock, it is called weathering. Sometimes water seeps into cracks in a rock and freezes, taking up more space and ultimately cracking the rock. Trees sometimes speed up rock cracking with their roots. As the roots grow, they creep between cracks and when they thicken, they force the cracks to open wider.
Have you heard about the earth? Water, wind, and ice shape and reshape its surface.
Once rocks are weathered, they are often transported by rain, wind, or flowing water in a process called erosion. As water rushes from its source, in the highlands, down to the sea, it constantly picks up chunks of rock, sand, and mud along the way. Wind picks up small pieces of rock, sand, and soil and carries it to other places. When weathered rock is picked up and moved by wind or water, it is called deposition.
Have you heard about the earth? Water, wind, and ice shape and reshape its surface.
Landforms, natural features on Earth’s surface, can change over short or long periods of time. Some landforms, such as valleys and canyons, can take millions of years to form by swiftly running rivers or enormous masses of ice called glaciers. When glaciers melt, they show how much of the Earth has been gorged away, leaving U-shaped valleys behind. Oceans shape the coastlines, which are where oceans meet the land. Ocean waves also pound rocky cliffs, changing their appearance and making them smaller.
Have you heard about the earth? Water, wind, and ice shape and reshape its surface.
Wind also changes the shape of the Earth’s surface by carrying sand and bits of rock. Strong winds can pick up huge amounts of loose sand and pile it up in heaps or hills, called dunes. Unusual rock formations are also a result of wind erosion, where swirling sand attacks cracks in rocks.
Have you heard about the earth? Water, wind, and ice shape and reshape its surface.
Some changes to the Earth’s surface occur quickly, like volcanoes, earthquakes, and landslides. Earthquakes and volcanoes can take place when two plates that run side by side, move against each other. They can also cause landslides, where large amounts of loose rock and soil move rapidly. The force of gravity and storms can also cause landslides. Floods and mudslides can play a role in shaping the land, too.
Have you heard about the earth? Water, wind, and ice shape and reshape its surface.
Earth is always changing. Mountains are building up and wearing down, while continents drift and shift apart. Oceans are getting bigger, while others grow smaller. Volcanoes are erupting and earthquakes are cracking open the earth’s surface. Rivers will dig great canyons, and glaciers will carve new valleys.

Big Picture/World Map Pictorial
Background Information (BI)
Earth’s surface is covered by a layer of rock called the crust. Beneath the crust is the mantle, the thickest layer of the earth. The mantle is so fiery hot that it actually melts rocks. The heat changes the rocks into a thick, heavy liquid called magma. Underneath the mantle is the earth’s core, which is composed of solid rock, iron and nickel.
The Earth’s crust consists of the oceanic and continental crust. Earth’s crust is made up of 30 huge rocks, called tectonic plates, which fit together like a jigsaw puzzle. These plates have been moving for millions of years and currently drift at rates of about one to four inches each year. As the continents formed, the plates crashed into each other forming mountains, and causing earthquakes and volcanoes. The main seven plates are labeled on this map.
The Subduction zone is an area on Earth where two tectonic plates meet and move towards one another, with one sliding underneath the other and moving down into the mantle (diagram – opposing arrows, one under another), at rates typically measured in centimeters per year. This often involves an oceanic plate sliding beneath a continental plate (though subduction zones can occur at the boundary of oceanic plates) and typically creates an orogenic zone or volcanic arc subject to many earthquakes. In a sense, subduction zones are the opposite of divergent boundaries, areas where material rises up from the mantle and plates are moving apart.
About 250 million years ago, the Earth had one huge supercontinent called Pangaea. There are seven continents today on Earth, which include Asia, Africa, North America, South America, Europe, Australia, and Antarctica.

BI – California Pictorial
(First two paragraphs only used if World map/tectonic plates pictorial is not used – this content is important to understand so we include it in whichever big picture graphic organizer is used for the unit–the California Map or the World Map.)
The Earth’s surface is covered by a layer of rock called the crust. Beneath the crust is the mantle, the thickest layer of the earth. The mantle is so fiery hot that it actually melts rocks. The heat changes the rocks into a thick, heavy liquid called magma. Underneath the mantle is the earth’s core, which is composed of solid rock, iron and nickel.
When Earth was first forming, there was just one continent, a huge land mass called Pangaea. Over time, billions of years, this mass separated into the seven continents we have today. The Earth’s crust consists of the oceanic and continental crust. Earth’s crust is made up of 30 huge rocks, called tectonic plates, which fit together like a jigsaw puzzle. These plates have been moving for millions of years and currently drift at rates of about one to four inches each year. As the continents formed, the plates crashed into each other forming mountains, and causing earthquakes and volcanoes.
Twp of these plates meet at the coast of California, and their movement has helped shape the land. California is a state that contains many different types of landforms that were formed through both slow and fast processes. North to South the state is 800miles long. East to West it is about 250 miles wide. Mountain ranges border the coast and form a natural border between California and its neighboring states, Oregon, to the north, Nevada and Arizona to the east, and Mexico to the south. The capitol of California, Sacramento, is located in northern California, in the San Joaquin Valley near the Sacramento/San Joaquin River delta.
The California Coast is one of the most beautiful places in the world, with many different types of landforms: Valleys, Deserts, Mountains, Coast, Delta, and more. Sharp, dramatic cliffs formed by weathering, erosion and deposition, and broad beaches made of sediment and sand.
The San Joaquin Valley, which millions of years ago was an inland sea, is considered the “nation’s salad bowl,” and many types of crops are farmed there. The San Joaquin/Sacramento River delta protects the land from the forces of the ocean, and is home to many types of wildlife,
The Sierra Nevada Mountains are home to famous and beautiful natural landforms like Lake Tahoe, Yosemite Valley and King’s Canyon. Millions of years ago, the range was just 3000 feet tall and the ocean extended over the land, covering an oceanic ridge. Those ancient mountains eroded away into the San Joaquin River Valley. Later volcanoes formed, then glaciers, then the majestic mountains we see today, some rising over 12,000 feet (show Mt. Whitney, tallest mountain).
California has two major deserts: the Mojave Desert, where Death Valley is located and the Anza-Borrego Desert which borders Mexico. The desert is a diverse ecosystem with very little water.
The land was formed through fast processes (earthquakes, volcanoes and landslides), and slow processes (WED – Weathering, Erosion, Deposition). The geography of California changes over time through geological processes in a dynamic duet of cause and effect.

BI- Sierra Nevada
The Sierra Nevada, which means “snowy mountain range” in Spanish, stretches 400 miles reaching north to south across the state of California. The Sierra Nevada is comprised of numerous landforms, such as Mt. Whitney, the tallest mountain in the contiguous U.S at 14,505 feet. The Sierra Nevada mountain range is also the home of the famous Yosemite Valley, and Lake Tahoe, the largest alpine lake in North America.
The Sierra Nevada has experienced great geological change through a mixture of fast and slow processes. Millions of years ago, volcanoes erupted in the Sierra region. Large igneous deposits covered the area north of Yosemite as a result of the volcanoes. Also, subduction zones, or areas on Earth where two tectonic plates meet and move towards one another, caused many earthquakes in the region. This caused uplift of the Sierras, which in turn increased the speed of stream flow, impacting the formation of V-shaped valleys in the region.
However, glaciation, or the slow movement of large masses of ice, is responsible for the U-shaped Yosemite Valley. Other fast and slow processes also play a role in the formation of the Sierra Nevada region such as landslides, or the down slope movement of rock, and exfoliation, where rocks peel off in sheets. The WED process, composed of weathering, erosion, and deposition, are all slow processes that also change the appearance of the Sierra Nevada.
Unfortunately, because of global warming, the snowmelt in the Sierra Nevada is expected to be reduced by half in the coming decades. This is a problem because California depends on seasonal snowmelt in the Sierra Nevada to provide water to the state. Animals such as the Yosemite toads, Pacific treefrogs, and garter snakes are also threatened by climate change.

How California was Made – A Native American Legend by the Gabrielino Native people, Southern California Tribe
1. Long, long ago, before there were people, there was hardly anything in the world but water. One day, Great Spirit looked down from heaven. He decided to make a beautiful land. “But where could he begin?” he said aloud. All he saw was water.
2. Then he spotted a giant turtle. “Turtle come,” he beckoned and turtle came to the Great Spirit. The Great Spirit decided to make the beautiful land on the turtle’s back.
But one turtle was not big enough. The land that the Great Spirit wanted to make was very large. So he called out, "Turtle, hurry and find your six brothers."
3. Turtle swam away to find them. It took her a whole day to find the first. It took another day to find the next. After six days, Turtle had found her six brothers. "Come," she said. "The Great Spirit wants us."
4. Great Spirit called down. "Turtles! Form a line, all of you -- head to tail, north to south. Umm -- you have three on the south, please move a little to the east. Hmmm. Yes, that’s just right. What a beautiful land you turtles will make! Now listen! It is a great honor to carry this beautiful land on your backs. So you must not move!"
5. The turtles stayed very still. Great Spirit took some straw from his supply in the sky. He spread it out on the turtle’s backs. Then he took some soil and patted it down on top of the straw.
6. Great Spirit cleaned his hands on a fluffy white cloud. Then he went to work, shaping mountains and valleys and lakes and rivers. When he was finished, he looked at the beautiful land he had made. Great Spirit was very pleased. But soon trouble began. The giant turtles grew restless. They wanted to stretch their legs.
7. "I want to swim east," said one.
"I want to swim west, with the setting sun," said another.
8. The turtles began to argue. They could not agree which way to move. One day, four of the turtles began to swim east. The others began to swim west. The Earth shook! It cracked with a loud noise.
9. But after a minute, the shaking stopped. The turtles had to stop moving because the land on their backs was so heavy. They had only been able to swim a little way from each other. When they saw that they could not swim away, they stopped arguing and were at peace again.
10. Every once in a while, though, the turtles argue again. Each time they do, the Earth shakes!
Sierra Nevada Narrative Input
By Anne Ginnold
Adapted from Chapter 1 of “Geology of the Sierra Nevada” by Mary Hill. (copyright permission to reprint granted by Anne Ginnold)
1. Although the Sierra Nevada seems old to us, in geologic time it’s just been in existence for 440 million years, one-tenth of the Earth’s 4 Billion year history.
2. From looking at the layers of rock in today’s Sierra Nevada foothills, we know that the Sierra Nevada began its life under the sea, and remained underwater for 240 million years.
3. Then deep within the earth, bodies of molten granite began to cool into rock, a process that took 130 million years to complete!
4. The hot rock began to rise towards the surface, disrupting the layers of sediment in the sea, pushing them aside, melting others. Today, these layers can be seen in the foothills.
5. In the High Sierra, blobs of the old rock, caught up in the younger granite, are found near the high peaks, remnants of a vanished sea that have not yet eroded away. Valuable mineral deposits formed where old rocks and granite met. Gold and other metals were left in veins and fissures as the last of the Granite cooled.
6. Over time the forces of erosion then began to attack the new mountain range, tearing rock from the mountainside to wash down rivers into a shallow, subtropical, lagoon-margined sea. Sierran rivers, not all where they are today, ran in broad valleys flanked by hills rising gently eastward. Altogether 9 vertical miles of rock was eroded over the next 25 million years, filling the shallow sea with sediment, and forming the Central Valley.
7. About 30 million years ago, volcanoes began to erupt. Violent explosions blanketed the northern Sierra with hot ash. The ash was followed by mud flows, leaving only a few projected peaks. Shortly after this, the Sierra began to rise rapidly.
8. By whatever means-earthquakes certainly had a part - the Sierra was lifted high enough for glaciers to form.
9. The earth grew colder, glaciers formed, changing the shape of the peaks and valleys. The years of the great glaciers – sculptors with ice and snow – had begun.
10. From looking at the layers of rocks we can learn about the processes that formed the mountains, eroded them away, and reformed them into the majestic mountains of today. We can see fossils of animals long dead or extinct and plants they used to eat. By looking at the land and how it was formed, we can deduce what types of landforms existed in the past. The Sierra Nevada is a young range. The seas are gone, the volcanoes are presently quiet, and even the earthquakes are not strong enough to move mountains. But over time, over millions of years, the land will continue to change through fast and slow processes. Who knows what California will look like in a million years!

W.E.D. Bugaloo
I’m a geologist and here to say,
I study how the land is shaped everyday.
Weathering breaks rocks into smaller pieces,
Which changes the shape and it’s size decreases.
Freezing, thawing, plants, wind, and pressure
Add on to the weathering measure.
Weathering, Erosion, Deposition, too
Doing the W.E.D. bugaloo!
Weathering and erosion work together.
Erosion carries rocks that have been weathered.
Flowing water is the biggest cause of erosion.
It transports sediments into streams, rivers, and oceans.
Weathering, Erosion, Deposition, too
Doing the W.E.D. bugaloo!
When sediments settle in a new place,
Deposition is the name in this case.
Flowing water deposits pieces day by day,
But wind picks up and settles them miles away.
Weather, Erosion, Deposition too
Doing the W.E.D. bugaloo!

Rock Cycle Chant
(Three Blind Mice)
The rock cycle
Occurs over time.
Earth’s surface is changed
By the rock cycle.
It’s composed of three types of rock
Classified as igneous,
Sedimentary, and metamorphic rocks
The rock cycle.
Igneous rock,
Means “made from fire”.
Born from a volcano.
Molten magma melting,
Will cool and solidify.
Granite and basalt are a couple types.
Have you ever seen such a sight?
As igneous rock.
Sedimentary rock,
Means “made from sediments”.
Formed under pressure.
Found near bodies of water.
Weathering and erosion play a role
Helping to make these rocks whole
Two examples are limestone and coal.
Sedimentary rock.
Metamorphic rock,
Means “change of form”.
The process occurs
Through heat or pressure.
Transformation happens over time
Of the texture or minerals inside.
Marble, slate, quartzite, and gneiss
Metamorphic rock.

I’m an Earthquake
I’m an earthquake on a fault
Holding energy to shake things up.
Earth’s tectonic plates try to slide,
But instead friction makes them grind.
I’m an earthquake
I’m an earthquake
Tectonic plates begin to move
Releasing energy triggering a quake.
My waves are under construction
Causing violent shaking and destruction.
I’m an earthquake
I’m an earthquake
My S and P-waves travel through the ground
Shifting buildings, moving them up and down.
The epicenter is where I start to shake
Above this point is where things break.
I’m an earthquake

Mountains here, mountains there.
Mountains, mountains everywhere.
Stratified mountains eroding slowly,
Fiery mountains erupting quickly,
Snowy mountains melting gradually,
And tall mountains forming.
Mountains in the Sierra Nevada,
Mountains under the ocean,
Mountains along the coast,
And mountains across the world.
Mountains here, mountains there.
Mountains, mountains everywhere.
Mountains! Mountains! Mountains!

California Coast
The Shoreline, or coast, is the boundary where the land meets the ocean. The western border of California extends about 800 miles along the Pacific Ocean. The northern half of this coastal region in California is known for its powerful wave action, rocky shores, and steep jagged cliffs, while the central, and southern half of the California coast is scattered with miles of sandy beaches and calm bays.
| |
| |
| |
| |
| |
The coast is continually changing because of the constant attack of wind and water. Moving wind and water along the shoreline are the major causes of weathering and erosion. Also, the fast and powerful force of waves can change the rocky cliffs that surround the coast. The continuous action of the waves breaks large rocks off at the base of the cliffs. Eventually, over a long period of time, the rocky cliffs become smaller, or collapse and fall. This erosion process also produces sand that forms into beaches.
| |
| |
| |
| |
| |
| |
| |
Another force that can reshape the coastal region is an earthquake. Most earthquakes occur near the edges of the Earth’s Tectonic plates. The Pacific and the North American plates meet at California’s coastline. The land located where two plates meet has more frequent earthquakes as the plates grind against and pull apart from each other. The coast of California is a subduction zone, which means that one plate is continually pushing under another, creating both small and large earthquakes. A powerful earthquake can reshape the land in a matter of minutes.
| |
| |
| |
| |
| |
| |
There is evidence that global warming is contributing to the rising of the water in the ocean. Climate changes in the Arctic are causing glaciers to melt at a faster rate. As these huge masses of ice melt, the water level in the oceans rises. In addition, the melting of this protective ice leaves the dark ocean exposed, which forces the ocean to absorb more heat and energy from the sunlight, further increasing the temperature of the sea. This rising of water and temperature threatens the habitats and food sources of both sea and shoreline animals.

Central Valley
The Central Valley in California is a large valley located in the center of the state. It is about 400 miles long and 30 to 60 miles wide. The valley is bordered on the west by the Coastal Ranges, and on the east by the Sierra Nevada mountain range. Summers in the valley are hot and dry, while winters tend to be moist and are often blanketed in fog. The Central Valley is known for it’s fertile soil and is often referred to as the “nation’s salad bowl.”
| |
| |
| |
| |
| |
| |
The formation of this large landform was a slow process that took millions of years to form. Valleys form as a result of a process called physical weathering. Physical weathering begins at the top of a mountain when rain falls and snow begins to melt. The water from the melted snow and rain forms small streams that converge together to form rivers that begin to flow downhill. As rivers flow down hills they begin to carve a path in the land by breaking away bits of rock. As the water travels down hill it also begins to slow down and flatten out. This flattening out of the water at the bottom of the mountains creates the V shape of a valley.
| |
| |
| |
| |
| |
| |
Another landform that can be found in California that is similar to a valley is a canyon. Instead of a V shape, canyons are deep, narrow valleys that have steep sides and often have rivers at the bottom. Two canyons that can be found in California are Kings Canyon and Red Rock Canyon. One famous canyon in the United States is the Grand Canyon. It was carved by the fast moving water of the Colorado River over millions of years.
| |
| |
| |
| |
| |
| |
While the Central Valley is one of the richest agricultural centers in the world, it is also one of the most polluted regions in the state and country. Pollution accumulates as a result of the emissions of toxic gasses from automobiles and industry in the valley region. In the summer months these gasses become trapped in the bowl of the valley because of hot summer temperatures and little air movement. This pollution in the valley increases the effects of global warming.

Sacramento-San Joaquin River Delta
The Sacramento-San Joaquin River Delta is a collection of small, natural and man-made channels that create a unique system of islands and wetlands. This major delta system is located at the western end of the Central Valley where the Sacramento and San Joaquin rivers converge together. The water exits the Central Valley, and delta, through a channel called the Carquinez Strait. Eventually the water flows into the San Francisco Bay, and finally to the Pacific Ocean. The total area of the delta is about 1,100 square miles.
| |
| |
| |
| |
| |
| |
A delta is a landform that is the result of sediments that are deposited at the end of a river where it slows down and empties into the ocean. A typical river delta narrows at the point where the river enters the delta and then fans out into the body of water that it empties into.
| |
| |
| |
| |
| |
| |
The Sacramento-San Joaquin delta is not a typical river delta. It is an inverted river delta. Instead of narrowing as it enters the delta, the water fans out at the end of the Central Valley, and then narrows as it moves into the Carquinez Strait.
| |
| |
| |
| |
| |
The delta system in California was originally a marshland. For thousands of years, huge areas of the delta flooded regularly each spring. As a result of these floods, this marshland soil turned to peat, a soil rich in partially decayed vegetation. Even though peat makes it possible for farmers to grow an abundance of crops, the decomposition of the organic materials (plants, trees) releases methane gas into the atmosphere. Methane Gas is a very powerful greenhouse gas that is a main contributor to global warming. While release of Methane gas is the natural effect of decomposition, this, combined with other human-made causes of global warming is of concern to scientists studying about how to preserve our earth.

Mojave Desert
The Mojave Desert is located in Southern California near the border of Nevada and California. A desert is a landscape, or region that receives very little precipitation and where vegetation is sparse or non-existent. The Mojave Desert is special because it has a little bit of everything. The Mojave Desert covers 25,000 square miles.
| |
| |
| |
| |
| |
| |
Wind is one of the slow forces that shape the desert landscape. The wind sculpts the face of the desert landscape by creating sand dunes. Sand dunes are formed when particles of sand are picked up by wind and moved to a new location. Different shapes of dunes are formed because as dry sand blows, objects such as rocks and grasses block the sand. This causes the landforms to take different shapes like wavy ridges, stars, or crescent moons. Swirling sand carried by wind also creates unique rock formations by a process called abrasion, where sand beats against the soft spots of rocks and erodes it.
| |
| |
| |
| |
| |
| |
Another important force affecting the desert landforms is water. While rain is not prevalent in the desert, it is a powerful force. Normal rainfall in the desert is a slow process that will wash away rock and sandstone creating new rock sculptures. However, a flash flood can reshape the land overnight. Eventually every part of rock in the desert will be eroded by wind or water.
| |
| |
| |
| |
| |
There are also human factors that contribute to the reshaping of the desert. Global warming increases the temperature of the atmosphere increasing the likelihood of a drought. Even small changes in temperature, or precipitation will drastically impact plants and animals that depend on the natural features of the land. Other factors such as the use of off-road vehicles, dirt biking, and dumping of nuclear waste also have a detrimental effect on this unique landform.
