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
Yeah I would prefer that, But most beach have man-made infrastructures now, such as lifeguard posts, changing rooms, and showers.
Yes they do and thank goodness for those, I cant STAND riding home all sandy and grimey feeling. I also HATE porta-potties and most beaches dont use them anymore and instead have an actual bathroom building
It has been said that today most wild beaches, also known as undeveloped or undiscovered beaches are pretty rare.
