Respuesta :
Two things that determine or influence the composition or the size of sand on beaches. The energy or height of the waves, and the size of material furnished to the beach. The higher the average waves on a beach, the coarser the sand. This is because higher waves tend to move the smaller grains offshore. The difference in size is due to winds that generally pick up and carry finer grains and leave the heavier, larger sand grains behind.
The two factors that influence the composition of beach material include
the following:
- The nature of the source.
- The intensity of the erosional processes.
What is Erosion?
This is defined as the process in which materials on the earth are washed
away as a result of factors such as wind or water.
Beach materials are usually washed from coastal regions and their
composition is based on the chemical compounds present in the source
or the intensity of the erosion.
