They prevent rapid extreme temperature changes. They form high-pressure areas that cause magma currents. They provide the energy that triggers volcanic events. They lower the freezing point of fresh water.
I gave my students this multiple choice question: Because water can hold a large amount of heat, which effect do oceans have on nearby land areas?

Only one answer is correct among these 4 choices:
- They prevent rapid extreme temperature changes.
- They form high-pressure areas that cause magma currents.
- They provide the energy that triggers volcanic events.
- They lower the freezing point of fresh water.

Could you tell me which one is correct?

They prevent rapid extreme temperature changes.
