Earth Sci Ch. 4 Rocks

3. (type of metamorphism) is the formation of metamorphic rock bodies that are hundreds of square kms in size
7. the broken pieces and rock fragments
14. any process that affects the structure or composition of a rock in a solid state as a result of changes in temperature, pressure, or the addition of chemical fluids
16. metamorphic rocks that have mineral grains with a random, interlocking texture
19. the broken pieces and fragments of rock
20. molten rock that erupts on Earth's surface
21. the grain size and the way grains fit together in a rock
22. the weight from the layers of sediment forces out fluids and decreases the space between grains

1. type of rock formed when volcanic material erupts and cools and crystallizes on Earth's surface (type of igneous rock)
2. rock that forms when lava cools too quickly to form crystals
4. permanent change in shape (of a rock) by bending and folding
5. a sedimentary rock that was formed by organisms or contains the remains of organisms
6. rock that forms when minerals crystallize directly from water
8. when minerals dissolved in water crystallized between sediment grains
9. fragments making up rocks
10. contain parallel layers of flat and elongated minerals
11. rock material that forms where rocks are broken down into smaller pieces or dissolved in water as rocks erode
12. the series of processes that change one type of rock into another
13. igneous rocks forming as magma cools underground
15. molten or liquid rock underground
17. (type of metamorphism) occurs when magma comes in contact with existing rock and its thermal energy and gases interact with the surrounding rock, forming new metamorphic rocks
18. a natural, solid mixture of minerals or grains
