Detailed explanation-1: -The global ocean conveyor belt is a constantly moving system of deep-ocean circulation driven by temperature and salinity. The great ocean conveyor moves water around the globe. The ocean is not a still body of water.

Detailed explanation-2: -A current is a large stream of water that flows through the ocean. Scientists put ocean currents in two categories: surface currents and deep currents. Surface currents move near the surface of the ocean. The figure below shows Earth’s major surface currents.

Detailed explanation-3: -Wind-driven surface waves and the tides stir the surface layer so the heat is distributed throughout the top few hundred meters of ocean water.

Detailed explanation-4: -Tides create a current in the oceans, which are strongest near the shore, and in bays and estuaries along the coast. These are called “tidal currents.” Tidal currents change in a very regular pattern and can be predicted for future dates.

Detailed explanation-5: -Large-scale surface ocean currents are driven by global wind systems that are fueled by energy from the sun. These currents transfer heat from the tropics to the polar regions, influencing local and global climate.
