Liam+and+Chris+Ocean+Temperature

**By Chris Mele and Liam Sullivan Orange-5**

 * Salinity lowers freezing point and raises the boiling point of the ocean.**

=**Top layer of ocean is the** **mixed layer: //COLD//**=


 * only layer to sustain photosyntesis
 * Temperature is affected by the latitude of the ocean and the season
 * most sea creatures live or atleast feed in this layer

= = =Second layer is called the **thermocline**: //COLDER//=


 * most temperature drop happens in this layer.
 * 5 - 25 degrees **C (warm - cold)**

=**Third Layer is the** **Deep Zone: //COLDEST//**=


 * goes all the way to the bottom of the ocean.
 * Temperature drops another 1 - 3 degrees **F**
 * **VERY COLD**

This diagram, depicts the 3 majors layers in the ocean, and shows their aproximate denisity and temperature.
