C. Transports heat from the North Atlantic to the Indian Ocean. Explanation: The Antarctic Circumpolar Current is a massive ocean current that surrounds the Antarctic continent and plays many roles. One of the roles it plays is to connect the three main oceans (Atlantic, Pacific and Indian) and act as a transport system between them, transferring heat, salt and other elements. This role is vital in the global system of thermoregulation of the planet’s oceans.
The answer is A: it transports heat from the North Atlantic to the Indian Ocean. Explanation: The Antarctic Circumpolar Current refers to the largest ocean current on the planet. It surrounds the Antarctic continent, passes eastward through the southern parts of the Atlantic, Indian and Pacific oceans. It is the strongest or strongest current in the oceans and the only current that moves completely around the globe.
D. Reduces temperature fluctuations between seasons in North America. Explanation:
D. Transports heat from the North Atlantic to the Indian Ocean. Explanation: The Antarctic Circumpolar Current (ACC) is a cold ocean current that flows from west to east around Antarctica, in the same direction as the Earth’s rotation. It is the only one that connects the Atlantic, Pacific and Indian oceans, since it finds no continent along its entire trajectory that interferes with its circulation.
It should be noted that the flow of this current plays a crucial role in the transfer of mass, heat and other properties (such as nutrients for marine life) between the three oceans. In addition, it keeps warm ocean waters away from Antarctica, allowing the continent to maintain its huge ice sheet, i.e., it acts as a thermal insulator for Antarctica.
In this sense, the process of heat transfer by the Antarctic Circumpolar Current is as follows:
The water that comes from the North Atlantic Ocean is heated at the equator and in the subtropical latitudes, then goes towards Antarctica, but when they arrive in Antarctica they find the ACC, which in turn from west east collects this mass of water and prevents them from coming into direct contact with the frozen continent, and releases them again so that they continue to flow again towards the equator and cross the Indian Ocean at a higher temperature low (but still warm), as some of the heat brought in from the tropics was absorbed by the CAC.
