Bay

earth science Maturity 7-9 Next article →

A bay is a part of the coast that curves inward. It is a body of water that connects to a larger area. This larger area might be an ocean or a lake.

The land around the water helps protect it. This land can block strong winds. It also blocks big waves from the open sea. This makes the water inside a bay much calmer.

Bays form in several different ways. Some form when the earth's plates move. During the Paleozoic and early Mesozoic eras, the super-continent Pangaea broke apart. This movement left large bays like the Bay of Bengal. The Bay of Bengal is the largest bay in the world.

Other bays form through erosion. This happens when rivers or glaciers wear away the land. A bay made by a glacier is called a fjord. Rivers can also create bays called rias.

There are many types of bays to notice. An open bay is wide at its mouth. An enclosed bay has a mouth that is narrower than its widest part. This happens because of a peninsula. Some bays are semi-enclosed by islands. Other bays are behind barrier islands.

A large bay is often called a gulf. A small, circular bay is called a cove. Some bays are even nested inside larger ones. For example, James Bay is part of Hudson Bay in Canada.

Rules help define what a bay is. The United Nations uses a specific rule for this. The area of the bay must be large. It must be larger than a semi-circle drawn across the mouth. If it is smaller, it is called a bight.

These rules are important for laws. They decide who owns the water and the seabed. They also help manage fishing and sea trade. This is called a juridicial bay.

Bays have always been important to humans. They provide easy access to many fish. This helped people settle near the coast long ago. Later, they became very useful for sea trade. The calm water provides a safe anchorage for ships. This makes bays great places to build ports.

Many famous shipping areas are gulfs. These include the Persian Gulf and the Gulf of Mexico.
