Question

which is one characteristic of deep ocean currents?
deep ocean currents move quickly.
deep ocean currents are caused by winds.
deep ocean currents move cold water toward the equator.
deep ocean currents are affected by temperature but not by salinity.

Explanation:

• Surface currents move quickly, while deep ocean currents are slow.
• Wind drives surface, not deep, ocean currents.
• Deep ocean currents (thermohaline circulation) move cold, dense water from polar regions toward the equator.
• Deep currents are driven by both temperature and salinity differences (thermohaline).

Answer:

Deep ocean currents move cold water toward the equator.
