<u>ANSWER:</u>
The correct option is A: They transport heat over long distances affecting the wind that blows over the land.
<u>EXPLANATION:</u>
- Ocean currents carry cool or warm water or currents over long distances thereby affecting the wind that blows over the place bringing about a change in the climate.
- When the ocean currents carry cool air, the warm wind gets displaced by the cool air and therefore the climate of the place becomes cold.
- When the ocean currents carry warm air or water, the climate of the place becomes warmer.
- By transporting hot or cold currents, the ocean currents affect the climatic conditions of land and so bring about a change of weather.
