The term VAST BODY OF WATER can be summarized as an OCEAN, which is a large body of saline water that covers most of the Earth's surface. Oceans are divided into four distinct areas: the Pacific, Atlantic, Indian, and Arctic oceans. They are connected by the world's five oceans, which are the Mediterranean Sea, Red Sea, Persian Gulf, and the Caribbean Sea. Oceans are home to a variety of marine life, including fish, mammals, and invertebrates. They also provide important resources for humans, such as food, transportation, and recreation.
