I live close to the beach and I love to spend time at the beach, do you?

I do but I learned recently that not all beaches are made of sand. Some are made from rock, such as sand, gravel, shingle, pebbles, or cobblestones.

Oh thats interesting, Ive only seen sand beaches. Where are these pebble or gravel beaches at?

South America host some, but sometimes they can instead have a combination of mollusc shells or coralline algae mixed in.

Oh okay I see. Is that healthy for the beaches and the water? It might be nice to go to a beach where you dont get sand up in every part of you Lol
