Question

1. which of the following landforms is created primarily through the process of erosion, where a major agent of erosion cuts away rock and sediment over a long period?

a sand dune formed by wind deposition
a volcanic island built by magma accumulation
a river valley or canyon cut by moving water
a sedimentary rock layer formed by compaction and cementation

1. which of the three major chemical weathering processes is most likely to affect granite, a rock that is primarily composed of the mineral feldspar?

Explanation:

For question 13:

• Option A is a depositional landform, not erosional.
• Option B forms from volcanic deposition, not erosion.
• Option C is created by water eroding rock/sediment over time.
• Option D is a rock formation process, not an erosional landform.

For question 2:
Granite's feldspar undergoes hydrolysis, a chemical weathering process where water reacts with feldspar to form clay minerals, breaking down the granite over time.

Answer:

1. C. A river valley or canyon cut by moving water
2. Hydrolysis
