So, what is the difference between a sea and a gulf?
At the edges of the oceans are seas, a part of the ocean that is partially enclosed by land. For example, the North Sea borders the Atlantic Ocean. Gulfs and bays are bodies of water that jut into the land; a gulf is larger, sometimes has a narrow mouth, and is almost completely surrounded by land.
Is the Gulf of Mexico considered to be the ocean?
At present, however, oceanographers consider all other oceans and seas as belonging to the Atlantic, Pacific, or Indian oceans. The Arctic Ocean, the Mediterranean and Caribbean seas, and the Gulf of Mexico are considered marginal seas of the Atlantic Ocean.
Are seas the same as oceans?
In terms of geography, a sea is part of the ocean partially enclosed by land. Seas are found on the margins of the ocean and are partially enclosed by land. Here, you can see that the Bering Sea is part of the Pacific Ocean. Seas are smaller than oceans and are usually located where the land and ocean meet.
