Question

ocean currents have an affect on which two things
climate and weather
equator and poles
temperature and density
land and sea

Explanation:

Ocean currents transfer heat, influencing climate (long - term patterns) and weather (short - term conditions). The equator and poles are geographical regions, not directly affected by ocean currents in the way the question asks. Temperature and density are factors affecting ocean currents, not what they affect. Land and sea are just different environments, and ocean currents don't primarily affect them in the relevant sense. So the correct option is the one about climate and weather.

Answer:

A. climate and weather
