Ocean is a major body of saline water and covers 70% of the Earth’s surface. The primary oceans around the globe are – Pacific Ocean, Atlantic Ocean, Indian Ocean, and Arctic Ocean. The Equator subdivides the Pacific and Atlantic into northern and southern portions. We call the smaller regions of the oceans as seas, gulfs, bays, straits, and other names.
