Answer:
C. ocean currents
Step-by-step explanation:
Ocean currents designate huge portions of water moving in the seas and oceans of planet earth, which influence the climate of the regions in which they operate as they carry moisture and heat.
These large oceanic water flows are formed by the differences between atmospheric pressure and temperature variations, water salinity, terrestrial rotation movement (which influences its trajectory: right in the northern hemisphere and left in the southern hemisphere) and the displacement of air masses (winds). In addition, sea currents may or may not be orderly, directly influencing the climate, favoring marine life and biodiversity.
In short, oceanic currents represent the movement of colder water (at the earth's poles) and warmer water (equator line).
