2. The Three Groups of Sedimentary Rock?

3. The Three Groups of Sedimentary Rock
The Three Groups of Sedimentary Rock? Clastic – made from eroded rock particles that have accumulated together

4. The Three Groups of Sedimentary Rock
The Three Groups of Sedimentary Rock? Clastic – made from eroded rock particles that have accumulated together Chemical – formed from minerals that were once dissolved in water

The Three Groups of Sedimentary Rock? Clastic – made from eroded rock particles that have accumulated together Chemical – formed from minerals that were once dissolved in water Organic – made from the remains of once living organisms

6. Time for the Sedimentary Rock Lab

7. Time To Learn About Igneous Rock

8. The Source of Heat for Melting Rock in the Earth’s Interior?

9. The Source of Heat for Melting Rock in the Earth’s Interior
RADIOACTIVE PROCESSES DEEP WITHIN THE EARTH

10. The Source of Heat for Melting Rock in the Earth’s Interior
RADIOACTIVE PROCESSES DEEP WITHIN THE EARTH
Magma is molten rock below the Earth’s surface
Lava is molten rock above the Earth’s surface

11. How Igneous Rock is Divided into Two Groups

12. How Igneous Rock is Divided into Two Groups The two groups are based on where they form:

13. How Igneous Rock is Divided into Two Groups The two groups are based on where they form: Intrusive igneous rocks form below the Earth’s surface and have large crystals and a rougher surface

14. How Igneous Rock is Divided into Two Groups The two groups are based on where they form: Intrusive igneous rocks form below the Earth’s surface and have large crystals and a rougher surface Extrusive igneous rocks form above the Earth’s surface and have small crystals and a smoother surface

15. Now For An Igneous Rock Lab

16. How is Metamorphic Rock Made?

17. How is Metamorphic Rock Made
How is Metamorphic Rock Made? Metamorphic rock is made when pre-existing rock is heated and pressurized...but not to the point that that rock completely melts.

18. The Difference Between Contact and Regional Metamorphic Rock

19. The Difference Between Contact and Regional Metamorphic Rock
Contact metamorphic rock is found in the immediate areas around volcanic conduits (tubes). Only small areas of rock are changed.

20. The Difference Between Contact and Regional Metamorphic Rock
Regional metamorphic rock is found deep in the Earth’s crust and covers very large areas of rock.

21. What Are The Two Main Divisions Of Metamorphic Rock?

22. What Are The Two Main Divisions Of Metamorphic Rock?
Foliated: meaning the rock shows layers

23. What Are The Two Main Divisions Of Metamorphic Rock?
Foliated: meaning the rock shows layers
Non-foliated: meaning the rock does not show layers

24. What Are The Three Types Of Foliated Metamorphic Rock?

25. What Are The Three Types Of Foliated Metamorphic Rock?
Rock Cleavage – rock breaks in sheets

26. What Are The Three Types Of Foliated Metamorphic Rock?
Rock Cleavage – rock breaks in sheets
Gneissic banding – rock has mineral bands but does not break in sheets along those bands

27. What Are The Three Types Of Foliated Metamorphic Rock?
Rock Cleavage – rock breaks in sheets
Gneissic banding – rock has mineral bands but does not break in sheets along those bands
Schistosity – rock has “platy” layers resembling fish scales
