Idk if this sounds stupid but how dis beaches form? Did the earth just exist with a beach just like that or did sth cause beaches to form (with sand, shells, and stuff)
In: Earth Science
Over millions of years, wind, water, ice, the movement of the earth’s crust itself on the melted magma below, and even plants make rock crack into pebbles, pebbles ground into sand, sand ground into clay, and clay compress to rock. It is a large cycle.
Sand is moved by wind and water, and sometimes it accumulates for a while at the edge of the ocean, and we call it a beach. If the wind, rain and ocean currents change, the sand may be washed away and accumulate somewhere else and what was a beach becomes a rocky shore.
