Question

how do ocean currents affect temperature? check all that apply.
□ they carry cold water from the poles to the equator and cool air over land.
□ they flow north and then south below the equator.
□ they flow south and then north above the equator.
□ they move warm water from the equator to the poles and heat air over land.
□ they move east to west and create prevailing winds.
□ they move west to east and create seasonal winds.

Explanation:

To determine how ocean currents affect temperature, we analyze each option:

• "They carry cold water from the poles to the equator and cool air over land": Cold water from poles to equator can cool adjacent land air, so this is correct.
• "They flow north and then south below the equator": This describes current direction, not temperature impact, so incorrect.
• "They flow south and then north above the equator": Describes direction, not temperature effect, incorrect.
• "They move warm water from the equator to the poles and heat air over land": Warm water from equator to poles can heat land air, correct.
• "They move east to west and create prevailing winds": About wind creation, not temperature impact, incorrect.
• "They move west to east and create seasonal winds": About wind creation, not temperature impact, incorrect.

Answer:

• They carry cold water from the poles to the equator and cool air over land.
• They move warm water from the equator to the poles and heat air over land.
