|
|
|
the sun heats the air and ocean evenly everywhere
|
|
|
the heat inside the earth heats the ocean and the ocean heats the air
|
|
|
the sun cannot heat both the air and water, so one must heat the other
|
|
|
the sun heats air and water more at the equator because it receives more direct sunlight

Detailed explanation-1: -Surface currents in the ocean are driven by global wind systems that are fueled by energy from the Sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth’s rotation, and the position of landforms that interact with the currents.
Detailed explanation-2: -Answer: Warm ocean currents originate around the Equator because air at the equator is colder than air further north or south because the Sun’s most concentrated rays warm the Earth’s equator.
Detailed explanation-3: -When water at the ocean’s surface is heated by the Sun it gains energy. With enough energy, the molecules of liquid water change into water vapor and move into the air. This process is called evaporation. The water in the ocean is mostly saltwater, a mixture of salt and water.
Detailed explanation-4: -Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off. The world’s ocean is crucial to heating the planet. While land areas and the atmosphere absorb some sunlight, the majority of the sun’s radiation is absorbed by the ocean.
