Many people use the terms "ocean" and "sea" interchangeably when speaking about the ocean, but there is a difference between the two terms when speaking of geography (the study of the Earth's surface).
Seas are smaller than oceans and are usually located where the land and ocean meet. Typically, seas are partially enclosed by land.1

An ocean is a large expanse of salt water that covers three-quarters of the earth’s surface. It is bounded by the continents, or the equator, and other imaginary lines. Sea on the other hand, is a body of salt water that is surrounded by land on all or most sides, or that is part of one of the oceans.2
