The ocean is divided into marine life zones, based on availability of light, distance from shore, and water depth.
What are the characteristics of the ocean?
An ocean is a body of saline water that composes much of a planets hydrosphere. Salinity is a main defining component of the ocean, and it is the amount of dissolved solid material in the water. Although there are many dissolved salts in seawater, sodium chloride (commonly known as salt) is the most abundant.
