Question

Quizplus · Accepted Answer

Waves cause beach sand to be both well-rounded and well-sorted. Well-rounded refers to the smoothness of the grains, which occurs due to repeated collisions and abrasions with other grains by the action of waves. Well-sorted refers to the uniformity of grain sizes, which occurs due to the sorting action of waves that separate grains according to their size and density. Poorly sorted sand would be the opposite, with a mix of grain sizes and densities.
