how land masses affect the atmosphere
The ocean plays a fundamental role in shaping the climate zones we see on land. Illustration of major ocean currents throughout the globe. Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off. The worldâs ocean is crucial to heating the planet. While land areas and the atmosphere absorb some sunlight, the majority of the sunâs radiation is absorbed by the ocean. Particularly in the tropical waters around the equator, the ocean acts a as massive, heat-retaining solar panel.
