Why do we get sand on beaches but not soil?
In: Geology
Hey! Complementing what u/Mr-Macphisto said, actually beaches are a direct product of its surroundings in the continent side. If there are very resistent rocks (normally quartz-rich rocks), the beach will be formed by “normal” sand (tiny grains of quartz). But, in some cases there so much organic matter available that some type of soil can be formed, that’s the case of mangroves (that’s not called a beach, but it’s related to).
