Question

1. what type of landscape feature is primarily formed through the process of coastal erosion?

a. cliffs

b. valleys

c. sand dunes

d. floodplains

Explanation:

To solve this, we analyze each option:

• Option a: Cliffs are formed by coastal erosion (waves, wind, etc. eroding coastal rock).
• Option b: Valleys are formed by river erosion, not coastal.
• Option c: Sand dunes are formed by wind - blown sand deposition, related to coastal deposition or desert, not erosion.
• Option d: Floodplains are formed by river flooding and deposition, not coastal erosion.

So cliffs are the landscape feature formed by coastal erosion.

Answer:

a. Cliffs
