1. Rock Cycle
Builds, destroys, and changes rocks from one form to another.
Millions of years to happen.

2. Ways Rocks can Change:
Erosion – water, wind,& weather wear away at rocks
Cementation – sediments pressed together
Melting – heat from inside the E melt rocks.

3. Ways to become Igneous:
Sedimentary pulled into the crust & melts as magma
Metamorphic melts deep inside the Earth as magma
AND THEN: Cooling and Crystallization

4. Ways to become Metamorphic:
Sedimentary pulled into the crust – extreme heat & pressure
Igneous Intrusive: extreme heat & pressure
Igneous Extrusive pulled into the crust – extreme heat & pressure

5. Ways to become Sedimentary:
Igneous Extrusive erosion & deposition gives Sediments that cement & compact
Metamorphic exposed to surface, erosion & deposition gives Sediments that cement & compact

10. 1) Wind breaks small bits from large rocks
1) Wind breaks small bits from large rocks. Rain takes the particles to a creek. They drop to the bottom and harden over time into limestone.

11. 2) A volcano sends lava out of its cone
2) A volcano sends lava out of its cone. The lava cools as it falls and makes basalt.

12. 3) A slow river puts soft, wet clay on a dead fish
3) A slow river puts soft, wet clay on a dead fish. The piled clay lies in place for years. The fish body is replaced with stone.

13. 4) Melted rock moves in the Earth
4) Melted rock moves in the Earth. It cools as it nears the Earth’s surface.

14. 5) The weight and pressure of a mountain over time turns shale into slate.

15. 6) Space in packed sand on the sea floor fills with minerals in the water. These minerals over time become cemented and turn in to sandstone.

16. 7) Magma presses against limestone. Over time it forms marble.

17. 8) The continental plates move and make folds in the rock
8) The continental plates move and make folds in the rock. This pressure can cause granite to form into gneiss.

18. 9) The ocean waves blast coral into bits which settle on old shells
9) The ocean waves blast coral into bits which settle on old shells. The coral and shell particles build up. Over the years they harden together to form coquina.

19. 10) Lava flows in huge sheets on the Earth
10) Lava flows in huge sheets on the Earth. It cools quickly into obsidian.
