Which of the following statements about the antarctic circumpolar current is correct? a. it reduces temperature fluctuations between seasons in europe. b. it reduces temperature fluctuations between seasons in north america. c. it determines the frequency of el niño and la niña weather systems. d. it transports heat from the north atlantic to the indian ocean.

D. It transports heat from the North Atlantic to the Indian Ocean.

Explanation:

The Antarctic Circumpolar Current (ACC) is a cold oceanic current that flows from west to east around Antarctica, in the same direction as the Earth's rotation movement. It is the only one that connects the Atlantic, Pacific and Indian oceans, because it does not find any continent in 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 the maritime fauna) among the three oceans. In addition, it keeps the warm waters of the oceans away from Antarctica, which allows the continent to maintain its huge ice sheet, that is, 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 coming from the North Atlantic Ocean is heated in the equator and in the subtropical latitudes, and then goes to Antarctica, but when they arrive in Antarctica they meet the ACC, which, in its turn from west to 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 passing through the Indian ocean with a lower temperature (but still warm), since part of the heat brought from the tropics has been absorbed by the ACC.

true. earthquakes are felt whenever there is a slip around a fault in the rocks below the earth. this reorientation of faults create sesmic waves and is known as earthquake, the severity of which is measured in richter scale. these are more prominent in hilly regions as the rocks usually form faults to balance the pressures on it.
