Question

How does a deep ocean current compare to a surface one?

Answer 1

The answer to your question is C- colder , saltier , and denser why because they don't have the same density level and deep ocean water is more dense than surface. and also  From your feet to your knees the water feels icy cold and from your knees to your head the water feels warm. You probably wondered what causes this to happen. What you felt were warm surface currents and cold deep currents. Changes in the density set these currents in motion. some ocean currents are set in motion by the wind other ocean currents are created by something you can't feel or see. Differences in density of water can also cause currents to form and move. Density is affected by temperature and salinity. i hoped i helped
