Question

1. rocks are only weathered by physical processes.

a. true
b. false

1. all erosion processes require water.

a. true
b. false

1. all rocks can be broken down by weathering processes.

a. true
b. false

1. erosion can lead to the creation of features like deltas and beaches.

a. true
b. false

1. freeze - thaw cycles are a type of mechanical weathering.

a. true
b. false

1. plate tectonics do not influence weathering or erosion processes.

a. true
b. false

Explanation:

1. Rocks undergo both physical (mechanical) and chemical weathering (e.g., acid rain dissolving limestone).
2. Erosion can occur via wind, glaciers, or gravity without water.
3. All rock types (igneous, sedimentary, metamorphic) are susceptible to weathering over time.
4. Erosion transports sediment; when sediment is deposited, it forms deltas and beaches.
5. Freeze-thaw cycles break rocks physically by water expanding when frozen, fitting mechanical weathering.
6. Plate tectonics create mountains, volcanoes, and slopes, which directly affect weathering/erosion rates and processes.

Answer:

1. B. False
2. B. False
3. A. True
4. A. True
5. A. True
6. B. False
