Unit 2

1. forms from another rock because of heat and high pressure
5. when condensed liquid falls from the atmosphere back to Earth.
6. the process of liquid moving through something that is porous
8. naturally-formed solid made of one or more minerals
10. hardest mineral, rated 10 on the Mohs Hardness Scale
14. another name for the water cycle
15. rocks forms above the Earth's surface.
17. runoff helps add nutrients to fresh water and salt water
22. the softest mineral, rated 1 on the Mohs Hardness Scale
23. process of the water cycle when the plants release water vapor and oxygen.
24. created when groundwater touches hot rocks or magma below Earth's surface
25. a solid object with specific chemical composition. It has a crystal structure.
27. if a liquid cools at this speed, the crystals will be smaller

2. when the sediments are glued together to create the rock
3. small rocks like gravel, sand, silt, and clay.
4. rocks do this through the rock cycle
7. this also a part of the water cycle,even though we might not think that it is
9. plane surface where a mineral cleanly splits
11. when the gaseous phase loses energy
12. sandstone and limestone are types of this rock
13. when a volcano erupt, this is released into the atmosphere
14. resistance to be scratched
16. rocks forms within the Earth's crust.
18. an area of land that catches all precipitation and surface runoff
19. basalt and granite are types of this rock
20. a process where crystals form and grow
21. an underground area of sediment and rocks
26. when liquid phase changes to a gas phase
