1. ____ metamorphism. When high temps and pressure affect large regions of earth’s crust.
4. The name for layers of chemical sedimentary rocks that form as a result of the evaporation of water.
6. Rock ____. Continuous cycle of the remaking of rocks.
10. The primary feature of sedimentary rocks is this horizontal layering.
14. ____ bedding. Formed as inclined layers of sediment flowed forward across a horizontal surface.
15. The physical and chemical processes that transform sediments into sedimentary rocks.
16. Pieces of solid material that have been deposited on Earth's surface by wind, water, ice, gravity, or chemical precipitation.

2. ____ bedding. Particle sizes become progressively heavier and coarser towards the bottom layer.
3. ____ metamorphism. Very hot water reacts with rock and alters its chemistry and mineralogy.
5. Large crystals that form in solid rock by the reorganization of atoms during metamorphism.
7. Occurs when mineral growth cements mineral grains together into solid rock.
8. The type of metamorphic rock texture that does NOT have mineral grains arranged in wavy layers and bands.
9. Percentage of open spaces between grains in the rock.
11. Sediments that are laid down on the ground or sink to the bottoms of bodies of water.
12. ____ sedimentary rock. Formed from the abundant deposits of loose sediments.
13. The type of texture in metamorphic rock, such as schist or gneiss, whose minerals are squeezed under high pressure and arranged in wavy layers and bands.
14. ____ metamorphism. The change that occurs in rocks when they come in contact with magma.
