Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Currents can bring warmer water to parts of the world that would otherwise see different temperatures. This is a result of ____
A
Energy transferring from the hydrosphere to the lithosphere.
B
Energy transferring from the atmosphere to the hydrosphere.
C
Energy transferring from the hydrosphere to the atmosphere.
D
Energy transferring from the lithosphere to the biosphere.
Explanation: 

Detailed explanation-1: -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.

Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface.

Detailed explanation-3: -Surface currents 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-4: -Thermohaline circulation. This is a process driven by density differences in water due to temperature (thermo) and salinity (haline) variations in different parts of the ocean. Currents driven by thermohaline circulation occur at both deep and shallow ocean levels and move much slower than tidal or surface currents.
