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.

Answer 1

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

Explanation: Currents alter sea-surface temperatures, which in turn warm or cool the air blowing onto nearby coasts (e.g., the Gulf Stream warms Western Europe; the California Current cools coastal California). Options 3 and 4 are reversed about current directions (warm currents generally flow from the equator toward the poles; cold currents flow from polar regions toward the equator). Option 2 is true in a general sense but is less complete than option 1 for describing the climate impact on land.
