global conveyor belt

The global conveyor belt, also known as thermohaline circulation, is a continuous system of deep-ocean currents that transports warm and cold water across the world's oceans. Driven by differences in water temperature and salinity, it helps regulate Earth’s climate by redistributing heat. Warm surface waters move from the equator toward the poles, where they cool, become denser, and sink to drive deep currents that return toward the tropics. This process connects the world's oceans, influencing weather patterns, sea levels, and marine ecosystems. It’s a vital component of Earth's climate system, acting like a planetary-scale conveyor belt redistributing thermal energy.
