Beach








Yesterday,  I went to the beach. It is so interesting how the ocean works. For example, I put my rocks high up the beach and 15 minutes later when I came back they seemed to have moved. I know the beach didn't move. It was the tide. Gravity from the moon pulls the water making it rise and fall. I think the reason the moon doesn't pull us away with the water is because of the earth's gravity.

Am I right about this?
