A sandbar is a word used to describe a ridge of sand or gravel that is formed in the water along a beach, river or a lake. It means a long, narrow, underwater ridge of sand or rocks that is usually formed by the current of a river or ocean. You might see sandbars when you go to the beach, and they often appear as shallow water areas that are not safe for swimming. Sandbars can also be found in oceans, rivers or lakes, and can be dangerous if boats or ships do not carefully steer around them.
