I've never been to the beach but have tried to learn as much about as I can for that day that I do go. You know, A beach is a landform alongside a body of water
Oh I love the beach! I live near a lake beach but I've always wanted to go to the ocean.
Your so lucky, I'm envious. The small particles that form the composition of a beach are typically made from rock.
Ah I always wondered what the sand is made of. 
Thats right the rocks are sand ,gravel, shingle, pebbles, or cobblestones
