VOCABULARYocean current: movement of ocean water thatfollows a regular pattern.
surface current: horizontal movement ofocean water caused by wind near surface.
Coriolis effect: curving of straight pathdue to the Earth’s rotation.
deep current: stream-like movement of waterdeep below the surface.
VOCABULARY
density: the amount of matter in a givenspace or volume.
salinity: measure of the amount ofdissolved salts or solids in a liquid.
NOTES
decreasing temperature
increasing density
increasing salinity through freezing
increasing salinity through evaporation
