below the surface of the ocean, there are many layers. It's a basin of water, a very deep basin of water. just as your surroundings change on land as you move farther north or south-or up a mountainside-so, too, do the surroundings change as you move into deeper waters. the deeper the water, the darker and colder it gets. The pressure grows, too because of the weight of all that water pressing down from above.

Oceanographers divide the ocean into five different zones based on depth, light, and other features.
