warm warter compared to cold water is less dense
cold water compared to warm water is... more dense
high salinity water compared to low salinity water wil... sink because it is more dense
what moves surface currents? wind
what moves deep ocean currents? differences in temperature and differences in salininty
how does the coriolis effect influence the ocean? it moves the ocean waters to the right (clockwise) in the northern hemisphere and left (counterclockwise) in the southern hempisphere
surface currents move warm water to the? poles where the water will become cold and sink
