Some bays make very good harbors where there is shelter from high waves and wind. This makes it a good place to anchor a boat.

A bay is part of an ocean or lake that curves deeply into the land.
 

The coastline of an ocean, sea or lake has different types of rock along the shore. The areas with softer rock wear away over many years from wind and water action, forming a bay. Who decides whether a bay is a bay or a cove? Good question!

 

This is Hanauma Bay in Hawaii. It is a very popular swimming and snorkeling area. There are many tropical fish swimming around the coral formations you see. Notice the headland at the top of the picture.
