Title:Ocean Layering

Explanation of Topic (Definition, Key Points, Details)

The ocean is layered according to density. Low density waters are at the top of the ocean and high density waters are at the bottom. Oceanographers have established that the ocean has three different layers. These three layers are: *Surface Zone *Transition Zone *Deep Zone __**Surface Zone: **__ Because of the solar energy,the water in this area is the warmest. This zone is also known as the "mixed zone". In this zone is where the mixing of waters take place. Waves,tides and currents are all causes of water mixture. The depth and temperature,depends on the latitude season. The zone usuallyy spreads to about three-hundred meters and can sometimes have a depth of about four-hundred-fifty meters. This zone only takes up about two percent of the ocean water. __**Transition Zone: **__ Below the surface zone is the transition zone. This zone is located in between the warm layer above and the deep zone cold layer below. The transition zone includes a thermocline and associated pycnocline. This zone only takes up about eight-teen percent of ocean water. __**Deep Zone: **__ Below the transition zone is the deep zone. Sunlight never reaches this zone ,so water temperatures in this zone are very low. As a result, water density remains constant and high. The deep zone takes up about eighty percent of ocean water.
