Answer the following questions on a separate sheet of paper.

6. Describe how the granite of a mountain could change first into sandstone and then into quartzite.

7. Describe how a collision between continental plates can result in the formation of metamorphic rock.

8. rock cycle

.

Fill in the blank using the following words to complete each statement:

deposition, melting, magma, heat, cycle

  1. The series of processes that that slowly change Earth’s rocks from one kind to another is called the rock _______________.

  2. Plate movements help drive the rock cycle by helping to form _______________, the source of igneous rocks.

  3. Deep beneath the surface, _______________ and pressure can change sedimentary rock to metamorphic rock.

  4. Through the process of _______________, metamorphic rock can become magma.

  5. Sediment piles up on the ocean floor through the process of _______________.

If the statement is true, write true. If the statement is false, change the underlined word

or words to make the statement true.

  6. _______________ The process that breaks down granite into sediment is deposition.

  7. _______________ There are many pathways by which rocks move through the rock cycle.

  8. _______________ The processes of the rock cycle form a pattern of pathways.

  9. _______________ Surface events not subsurface events change rocks from one kind to another.

10. _______________ The collision of continental plates can push up a mountain range, after which weathering and erosion begin.

The Rock Cycle

Answer Key

[pic]

1. Each small block in the multicolor cube

represents a grain, a particle of a mineral or of

another rock.

2. The rock has an easily visible grain. Individual

grains (the sides of the small blocks seen on

the cube’s faces) are large, and their shape is

regular.

3. The rock is coarse-grained.

4. There is no pattern to the placement of the

different grains. They do not form layers,

bands of color, or swirling patterns.

[pic]

Through surface events such as deposition,

weathering, and erosion, sedimentary rocks are

formed from other types of rocks. Subsurface

events such as melting, earthquakes, volcanic

activity, heat, and pressure change rocks from one

type to another. All of these changes are a part of

the rock cycle.

[pic]

1. igneous rock

2. sediment

3. sedimentary rock

4. metamorphic rock

5. magma and lava

6. As the forces of mountain building slowly

push the granite upward, weathering and

erosion wear away the granite to form sand.

Streams carry the sand to the ocean where

layers of sediment pile up on the ocean floor.

The sediments get compacted and cemented

together to form sandstone. If pressure

compacts the sandstone particles further and

silica replaces the calcite holding the rock

together, quartzite will form.

7. A collision between continental plates can push

rocks down deep beneath the surface. Here,

heat and pressure could change the rocks to

metamorphic rock.

8. The rock cycle is a series of processes that occur

on Earth’s surface and in the crust and mantle

that slowly change rocks from one kind to

another.

[pic]

1. Only igneous rocks are involved in that

pathway.

2. Students’ flowcharts should show igneous rock

forming at the mid-ocean ridge, moving across

the ocean floor, being subducted at a deep-

ocean trench, melting into mantle material, and

becoming igneous rock again.

3. Metamorphic rock changes into sedimentary

rock, which changes into metamorphic rock

again.

4. Students’ flowcharts should show the formation

of metamorphic rock, the erosion of that rock,

the formation of sedimentary rock, and the

change to metamorphic rock.

5. Answers will vary. Students should describe the

processes that form the three major groups of

rocks.
