E)varies only with storm intensity and duration.

Question

Quizplus · Accepted Answer

The particles on a beach are typically derived from the local area and the materials that are locally available. The type of bedrock underlying the coastal area and the frequency of storms may indirectly influence the particle size, but the primary determinant is the availability of material. Seasonal variations can occur on any coast, depending on the local conditions. Storm intensity and duration may have a short-term effect on particle size, but the long-term trend is determined by local availability.
