Term | Definition |
---|---|
ocean currents | 1.ocean currents are stream like movements of water in the ocean. 2.surface currents are ocean currents that occur at or near the surface of the ocean. 3.the gulf steam is a surface current. |
surface currents | 1.surface currents are affected by continental deflections, the Coriolis effect, and global winds. 2.when surface currents meet continents they are deflected and change direction. 3.the deflection of moving objects from a straight path due to earths rot |
surface currents | 1.the major source of energy that powers surface currents is the sun. 2.the causes differences in temperature across earth which causes differences in air pressure. 3.winds form as a result of differences in air pressure and creates surface currents. |
deep currents | 1. deep currents are movement of ocean waters below the surface caused by differences in density. 2.density is the amount of matter in a given space or volume. 3.salinity and temperature cause differing ocean water densities. 4.salinity is a measure of |
