Ms. Mandel

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

3. 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.

Rocks are continually
changing.

7. What are the different types of rocks?
Igneous
Metamorphic
Sedimentary

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

9. What are the 2 types of igneous rocks?
Intrusive
Extrusive

10. Describe Intrusive Igneous Rock
Forms below the Earth’s surface from magma
Cools slowly
Large crystals form
Diorite
Gabbro
Granite
Pegmatite

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

12. Sedimentary Rocks

13. 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)

14. 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

15. Metamorphic Rocks
Before: Shale
After: Slate

16. Metamorphic Rocks
Before: Granite
After: Gneiss

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

18. Let’s Put It Together

19. 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.
