The ocean conveyor belt, also known as the thermohaline circulation, is a global system of ocean currents that transports warm and cold water around the planet. This movement is driven by differences in water temperature and salinity, which affect water density. Warm water from the equator moves toward the poles, while cold water from the poles flows back toward the equator. This circulation plays a crucial role in regulating the Earth's climate by distributing heat and nutrients across oceans. It influences weather patterns and marine ecosystems, making it essential for maintaining the balance of life in the ocean. Changes in the ocean conveyor belt can have significant impacts on global climate.
