Answer 3

A sea is a large expanse of saline water connected with an ocean, or a large, usually saline, lake that lacks a natural outlet such as the Caspian Sea and the Dead Sea. The Sea of Galilee is a small freshwater lake with a natural outlet, but the term was applied to it anyway. The term is used colloquially as synonymous with ocean, as in the tropical sea or down to the sea shore, or even sea water referring to water of the ocean. Large lakes are sometimes referred to as inland seas, such as the Great Lakes. Many seas are marginal seas.
