Question

which statement describes the impact of ocean currents on climate?
ocean currents create changes in the temperature of air over land masses.
ocean currents cause the temperature of air over large bodies of water to change.
ocean currents move cold water from the equator to the poles, creating cool weather regions.
ocean currents carry warm water from the poles to the equator to create warm weather regions.

Explanation:

Ocean - currents transport heat. Warm ocean - currents warm the air over land masses they flow near, and cold ocean - currents cool the air over land masses. They create changes in the temperature of air over land masses. Ocean currents don't mainly affect air temperature over large bodies of water compared to land. Also, they move warm water from the equator to the poles and cold water from the poles to the equator.

Answer:

Ocean currents create changes in the temperature of air over land masses.
