Although both Ocean and gulf are large water bodies, there are some differences between the two. The ocean is a larger water body compared to the gulf, and it does not have specific boundaries. Another important characteristic of an ocean is that it is one of the large bodies of water separating the continents.
Gulf, on the other hand, is a large body of water that is surrounded by land. In other words, the gulf is a portion of an ocean extending into the land. That is why gulf is also referred to as a landlocked sea.
Unlike oceans that do not have specific boundaries, gulfs are bounded by land, usually in three different parts. Another difference is that the water in the ocean is not as calm as that of the gulf. The waves in oceans are usually larger than that of gulfs. In terms of depth, oceans are deeper compared to gulfs.
