Do you like to go to the beach? I don't live near any bodies of water where you can find beaches. 
Yes, how are beaches formed?
They typically occur in areas where waves deposit and rework sediments like sand and small rocks. 
I see, what else do you know beaches?
In addition to being made of sand and rock, the particles on a beach can be biological particles, like shells and algae. 
I love collecting shells. Do you?
Well, I've actually never been to a beach so I've never collected them. Someday I'd like to go to a wild beach, one of those undeveloped beaches where I can see nature. 
Yes you should, beaches are great in the summer!
