1. sedimentary rocks are formed by the compaction and cementation of sedim

a. true
b. false

1. mass wasting is another term for erosion caused by gravity.

a. true
b. false

Explanation:

1. Sediments also deposit in non-aquatic environments like deserts (sand dunes) and glacial areas.
2. The Grand Canyon was primarily formed by fluvial erosion from the Colorado River, not just weathering.
3. Biological weathering is defined as rock breakdown by living things like plants, animals, and microbes.
4. Growing roots exert physical force that splits rocks, a type of mechanical weathering.
5. Weathering rates vary based on rock type, climate, and environmental conditions.
6. Landslides are a type of mass wasting, which is a subset of erosion driven by gravity.
7. Urbanization (construction, pollution) and agriculture (tilling, deforestation) speed up rock breakdown.
8. Erosion occurs in aquatic environments too (e.g., riverbed scouring, coastal wave erosion).
9. Sedimentary rocks form when sediments are compacted and cemented over time (lithification).
10. Mass wasting refers to gravity-driven movement of rock/soil, a form of erosion.
