1. Review for Unit 7 Test

2. Rocks change over a long period of time from one form to another through a process called

3. The rock cycle

4. What are the 3 kinds of rocks in the rock cycle?

5. Igneous Sedimentary metamorphic

6. What kind of rocks would be found near a volcano?

7. igneous

8. Rocks made of tiny pieces of sediment would be which kind?

9. sedimentary

10. When rock is exposed to ice, plant roots, and rain it is likely to break down into

11. sediments

20. The process of rock breaking down into sediments is called

21. weathering

22. The process of moving sediments from one place to another is called

23. erosion

24. Because Florida is made mostly of karst, it is a good place to

25. Find sinkholes and Mine gypsum and limestone and Find caverns

26. Is limestone dissolved by acid rain? Is this chemical weathering?

27. Yes and yes

28. What causes the most erosion?

29. water

30. What does magma become when it hardens underground?

31. granite

32. What does mechanical weathering result in? What does chemical weathering result in?

33. Sediments – small bits of rock Dissolved rock or chemically different rock

34. When you dig in Florida you will dig through layers in this order….

35. Topsoil Horizon 2 – mostly sand Horizon 3 – sand, clay and limestone Finally karst (limestone)

36. Why can’t someone dig a sinkhole?

37. They are naturally occurring, not manmade

38. That’s all folks!!!!
