Geology and Hydrology

4. The type of weathering that breaks rock into smaller pieces without changing its chemical composition
8. The most powerful agent of erosion
9. A chemical reaction where oxygen reacts with iron-rich minerals to produce rust
10. A landform created when waves lose energy and deposit sediment along a coastline
12. A process where water enters cracks in rocks, freezes, expands, and eventually breaks the rock apart
13. The process where rocks collide due to moving water or wind, resulting in smooth and rounded surfaces
14. The transport of broken-down materials or soil from one location to another

1. The primary work of a stream at its headwaters where it erodes the stream bed vertically
2. Underground formations that grow from the floor of a cave
3. Underground formations that grow from the ceiling of a cave due to mineral deposition
5. The type of weathering that changes the actual composition of minerals through chemical reactions
6. A weak acid formed when carbon dioxide combines with raindrops, capable of dissolving limestone
7. The gradual wearing down and lowering of mountains and landscapes over long periods
8. The process that breaks down solid rock into sediments at the place where they are found
11. A geological event where acidic groundwater dissolves limestone, causing the ground above to collapse
