Mrs. Sumerix - Welcome



Activity - Sequencing Events in Geologic HistoryRead this text and take notes from a class discussion led by your teacher before moving on. You will now use what you have learned so far about rock layers to determine the sequence of events in Earth’s history at different locations, based on the rock layers you observe. Be sure to refer to your notes and the text you just read to help you!Location 1: Order the events that happened from oldest to youngest. Layer C deposited FoldingLayer A DepositedLayer B DepositedBACBACYoungest EventOldest EventEvent What is your evidence?What law of stratigraphy supports your thinking?Explain how the Laws of Stratigraphy you indicated helped you order the events in the sequence they occurred.Location 2: Order the events that happened from oldest to youngest.

Letter A is located on a rock layer and line XY represents a fault. Annotate the diagram with all the ideas that you think will help you and your classmates determine the sequence of the events below.

Use the word bank below (keep in mind, there might be repeats occurring).Limestone depositedShale depositedFault along XYErosionSandstone depositedShale depositedSandstone depositedIgneous Rock IntrusionLimestone deposited Youngest EventOldest EventEvent What is your evidence?What law of stratigraphy supports your thinking?Explain - What does rock composition tells us about the history of rocks and Earth’s environment?In the diagram below you will see descriptions of the sediment mixtures you used to model each of the sedimentary rock layers during the explore phase. Use the ESRT to help you identify the type of rock that is represented by each one of the layers you created. -251460137160EDCBAmodern day beach Sand mixed with jagged medium sized pebblesSand with small rounded pebblesSand with shells and/or shell fragmentsSand mixed with dry bark or any other plant materialSand only 00EDCBAmodern day beach Sand mixed with jagged medium sized pebblesSand with small rounded pebblesSand with shells and/or shell fragmentsSand mixed with dry bark or any other plant materialSand only Sediment mixtureInfo from ESRT you used to identify the type of sedimentary rock that would form from each sediment mixtureType of sedimentary rock Based on ESRT Map SymbolDraw the map symbol used in the ESRT for this rock typeABSediment mixtureInfo from ESRT you used to identify the type of sedimentary rock that would form from each sediment mixtureType of sedimentary rock Based on ESRT Map SymbolDraw the map symbol used in the ESRT for this rock typeCDEName of Sedimentary Rock from previous tableWhat are your initial ideas about what the composition of each rock tells you about its past environment? Match the sedimentary rock types you identified with the environment you think it is associated with. Name of Sedimentary Rock types from previous tablePossible Environments:Beach with lots of snailsHigh energy landslide in a forestLong, high velocity riverBeach without many animalsShort length, low-medium velocity riverRead-Generate-Sort- SolveTransport EnvironmentThe sediment that forms sedimentary rock layers like the ones you modeled could have been transported in a number of ways. Read this text to help you think about the history of the rock sediment in layers C and E. Underline any information that helps you understand what the size and shape of rock pieces tell you about their journey to the ocean where they were deposited. Generate Ideas: Write all your ideas that you think are important for completing the Making Inferences about the history of rock sediment. Name: ______________Name: ______________Name: ______________Sort - Star the Ideas that are Most UsefulSolve - Write your Group’s Response! Solve the problem by completing the table below.Making Inferences about the History of Rock Sediment Sediment mixtureDescription of sediment What was the transport environment like for these sediments?Was it high or low energy?Did the rocks make a long or short journey?What’s your evidence and reasoning?In other words, explain your thinking using concepts from the text.
