2. when sediment is pushed together by the weight of water and other sediment pushing down on it
4. rock rock that forms when molten rock cools and hardens
6. All water on Earth's Surface - 71% of Earth's surface.
10. a natural, solid mixture of minerals or grains
11. how a mineral reflects light (how shiny it is) metallic vs. non metallic
13. the outermost layer of the Earth that is the least dense and rocky.
14. the amount of matter in a certain amount of space.
17. rock rocks that are formed from extreme heat & or pressure
18. molten rock on Earth's surface
19. small pieces of broken rock
20. The outer rigid layer of the Earth - 29% of Earth's surface.
24. Core the innermost, most dense layer of the Earth, made of mostly solid iron & nickel.
25. Layer of gasses surrounding Earth.
27. when sediment is glued together by the minerals as the minerals get into spaces between compacted sediment
29. the solid layer below the crust that is more dense than the crust, but not as dense as the cores.

1. All living organisms on Earth.
2. tendency of a mineral to split along flat surfaces
3. a naturally occurring, inorganic solid that has a crystal structure and a definite chemical composition
5. using your 5 senses to gather information.
7. igneous rock that cools slowly underground resulting in large crystals
8. igneous rock that cools quickly on the surface of the earth, resulting in small crystals or a glassy texture
9. when liquid rock cools and solidifies to form crystals
12. rock rock that forms from the cementation or compaction of sediments into solid rock
15. the amount of space an object takes up.
16. the amount of matter in an object.
21. Core the third layer of the Earth, made of liquid iron and nickel.
22. cycle series of processes that create and transform the types of rock in the Earth's crust
23. when a mineral breaks unevenly and there are no clear planes
26. a logical explanation based on observations.
28. molten rock under the ground
