Which explanation most accurately describes convection within the ocean? Question 2 options: Water near the equator is warmer because of direct sunlight. Water near the poles is cold and dense. Warm water moves toward the poles and cold water moves toward the equator. The Sun heats the surface of the water. The deeper the water, the colder it becomes. Warm water sinks and cold water rises. Earth's mantle heats water at the bottom of the ocean, causing the water to rise toward the surface. The air at the surface cools the water, causing the water to sink. Water near the ocean's surface is heated by air, causing it to sink toward the bottom of the ocean. As the water cools it sinks, causing it to rise back toward the surface.
