Weathering

5. A type of weathering caused by chemical reactions.
8. A honeycomb pattern created by the formation of salt crystals when ocean water evaporates.
11. Rock formed from the compaction and cementation of sand.
13. As igneous rocks are uplifted, the pressure from the surrounding rock decreases.
14. Igneous rock with large crystals.
15. A chemical reaction between the iron in rocks and oxygen in the air.
17. The process in which limestone dissolves.
18. The growth of these organisms on rocks produces chemicals that break down the minerals in the rock.
19. A type of mechanical weathering where water freezes in cracks, making them bigger and breaking down the rock.
21. This is caused by the expansion and contraction of minerals at different rates when there are temperature changes, and results in rocks shedding their outer layers.

1. When the surface of the rock is scratched.
2. A chemical weathering that transforms minerals into clay.
3. Rock formed from mud and silt.
4. The process of physically wearing down the rock without a chemical reaction.
6. Weather conditions of over a specific region that generally stay the same.
7. A type of chemical weathering that breaks down rocks by creating rust.
9. Rock composed of calcium carbonate that comes from the remains of living things. .
10. When tree roots grow into cracks of rocks, slowly forcing them apart.
12. The process caused by pressure release, where cracked layers of rock peel off like an onion.
16. The process of creating a solution when a solid becomes part of the liquid.
20. When rocks are broken down into sediments and soil by rain, ice, wind, and living organisms.
