b. false

1. rivers can create valleys through the process of erosion over time.

a. true
b. false

Explanation:

1. Weathering is defined as the breakdown of rocks into smaller fragments.
2. Erosion is the movement of weathered materials between locations.
3. Deposition is the process of sediments being deposited in a new area.
4. Mechanical weathering breaks rocks physically, no chemical changes.
5. Chemical weathering alters rock minerals, forming new ones.
6. Wind is a primary erosion agent in dry, arid regions.
7. Glaciers erode by grinding rocks with their weight and embedded sediment.
8. Soil formation involves weathering, erosion, deposition, and biological activity, not just deposition.
9. Rivers gradually erode land to carve out valleys over long periods.
