Across
- 5. a rock that is made up of broken pieces of minerals and rock fragments
- 9. a rock that contains parallel layers of flat and elongated minerals
- 10. rock material that forms where rocks are broken down into smaller pieces or dissolved in water as rocks erode
- 11. the process in which the weight from layers of sediment forces out fluids and decreases the space between sediment grains
- 14. molten rock that erupts on Earth’s surface
- 16. the formation of metamorphic rock bodies that are hundreds of square kilometers in size
- 20. a process in which magma comes in contact with existing rock, and its thermal energy and gases interact with the surrounding rock to make new metamorphic rock
- 21. a sedimentary rock that was formed by organisms or contains the remains of organisms
- 22. a type of igneous rock that forms when material that erupts from a volcano cools and crystallizes on Earth’s surface
Down
- 1. a permanent change in shape by bending and folding
- 2. an igneous rock that forms when lava cools too quickly to form crystals
- 3. the series of processes that change one type of rock into another type of rock
- 4. a rock formed when minerals crystallize directly from water
- 6. a broken piece of a mineral or a rock fragment
- 7. a fragment that makes up a rock
- 8. molten or liquid rock underground
- 12. a metamorphic rock that has mineral grains with a random, interlocking texture
- 13. the process in which minerals dissolved in water crystallize between sediment grains
- 15. the grain size and the way grains fit together in a rock
- 17. a natural, solid mixture of minerals or grains
- 18. an igneous rock that forms as magma cools underground
- 19. 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
