Question

which describes one feature of deep ocean currents?
have lower - salinity water
carry warm water from the equator
have higher - temperature water
move more slowly than surface currents

Explanation:

Deep ocean currents are driven by differences in water density (due to temperature and salinity). They are cold, high - salinity, and move slowly compared to surface currents which are mainly wind - driven. Surface currents can carry warm water from the equator, but deep ocean currents are not warm - water carriers from the equator. Also, deep ocean currents have higher salinity (due to processes like freezing which expels salt) rather than lower salinity.

Answer:

move more slowly than surface currents
