Detailed explanation-1: -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.

Detailed explanation-2: -Warm currents are those that travel from the Equator to the poles and are therefore warmer than the surrounding water. Whereas Cold ocean currents are substantial quantities of cold water moving towards the equator from a high altitude to a low height. They absorb heat from the tropics and chill the air above them.

Detailed explanation-3: -The main source of ocean heat is sunlight. Additionally, clouds, water vapor, and greenhouse gases emit heat that they have absorbed, and some of that heat energy enters the ocean. Waves, tides, and currents constantly mix the ocean, moving heat from warmer to cooler latitudes and to deeper levels.

Detailed explanation-4: -Ocean currents act much like a conveyer belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface.
