Question

Classify the type of erosion that could move sand along a shoreline

Answer 1

Answer:

• Erosion and deposition (shoreline retreat)

Explanation:

Sand moves along a shoreline through hydraulic and mechanical action (friction) of the waves. During this course, two phenomenons usually occur, i.e. erosion followed by deposition.

However, sometimes when the wave action is stronger, it leads to the coastal erosion or the shoreline retreat where a land part is permanently lost and the sand is moved with the waves forming beaches.
