What are tides?
When you go to the beach, have you noticed that sometimes the waves creep right up the beach… and sometimes they stop way back? These movements of the ocean are the tides. Tides are the regular rising and falling of the surface of the ocean. Tides occur twice each day. When the water level rises, it is high tide. When water it falls, it is low tide.
