The thermohaline currents of the oceans

Question

Quizplus · Accepted Answer

Thermohaline currents, also known as the ocean conveyor belt, are driven by differences in water density caused by differences in temperature and salinity. These currents bring nutrients up to the surface, which supports marine life, and also transport heat from the tropics to the poles, which helps to warm Europe and North America. While they do play a role in global climate, they are not major contributors to climate change. The strength and temperature of these currents vary and can be affected by changes in climate. The warmest waters of the ocean are typically found near the surface, not in the deepest parts.
