Question

How does wave refraction at headlands affect deposition and erosion?

A) Increases both deposition and erosion
B) Increases deposition, decreases erosion
C) Increases erosion, decreases deposition
D) Has no effect on deposition and erosion

Answer 1

Wave refraction at headlands affects deposition and erosion. The energy of the waves is concentrated on the sides of the headland, leading to increased erosion. Deposition occurs in the bays or areas of reduced wave energy behind the headland.

Step-by-step explanation:

Wave refraction at headlands affects deposition and erosion. When waves approach a headland, they change direction due to the varying depth of the ocean floor. As a result, wave energy is concentrated on the sides of the headland, leading to increased erosion. On the other hand, deposition occurs in the bays or areas of reduced wave energy behind the headland.
