The ocean, which we often break into five large ocean basins, covers 71 percent of the Earth's surface and holds over 1.3 billion cubic km of water. This massive space also holds over 99 percent of the area that can be inhabited by life, along with geological features, such as the world's largest mountain range and the deepest canyon. Despite its vast space, the ocean can be impacted by human actions. Watch and learn more in this video from TED ED.
