The Rock Cycle Ms. Mandel

D21 Explain how internal energy of the Earth causes matter to cycle through the magma and the solid earth.

Learning Targets I can explain how the internal energy of the Earth causes matter to cycle through the mantle and the crust. I can differentiate between the 3 different types of rocks.

Thinking about relationships among the major rock groups The Rock Cycle Thinking about relationships among the major rock groups

Naturally-occurring mixtures of minerals, glass or organic matter. What is a rock? Naturally-occurring mixtures of minerals, glass or organic matter. science.nationalgeographic.com

No Once a rock is formed, does it stay the same forever? Rocks are continually changing. imnh.isu.edu

What are the different types of rocks? Igneous Metamorphic Sedimentary

How are igneous rocks formed? Formed from the cooling of either magma or lava Most abundant type of rock

What are the 2 types of igneous rocks? Intrusive Extrusive elearning.stkc.go.th

Describe Intrusive Igneous Rock Forms below the Earth’s surface from magma Cools slowly Large crystals form Diorite Gabbro Granite Pegmatite http://geology.com/rocks/igneous-rocks.shtml

Describe Extrusive Igneous Rock Form when lava cools on or near the surface Fast cooling Small or no crystals Obsidian Pumice Basalt

Sedimentary Rocks

How are Sedimentary Rocks Formed? Formed from sediments Sediments moved by wind, water, ice or gravity Heavy sediments press down on the layers beneath (compaction) Dissolved minerals flow between particles and cement them together (cementation)

What are Metamorphic Rocks? Rocks that have changed due to temperature and pressure increases What types of rocks can form metamorphic rocks? Igneous Rocks Sedimentary Rocks Metamorphic Rocks

Metamorphic Rocks Before: Shale After: Slate

Metamorphic Rocks Before: Granite After: Gneiss

What other cycles interact with the Rock Cycle? Water (Hydrologic) Cycle Plate Tectonics

Let’s Put It Together

Learning Target Checkpoint How does the internal energy of the Earth cause matter to cycle through the magma and the solid earth? Differentiate between the 3 different types of rocks.
