The Ocean

-Covers more than 70% of our planets surface

-5 major oceans:

- Pacific

- Atlantic

- Indian

- Arctic

- Southern 

-Salt water -->  caled salinity 

-Always moving --> around surface ocean in the upper 400 m of the ocean 

-Moves around the ocean by upwelling (brings water from the deep ocean to the shallow areas) and downwelling (send water from the surface to the deep ocean) 

- The ocean water moves with tides --> created by gravitational force.  

- Ocenas make up 97% of worlds water

- The ocean has layers
