Explanation:

Explanation:  Both statements are correct Supplementary notes: Antarctic Circumpolar Current  The ACC is created by the combined effects of strong westerly winds across the Southern Ocean, and the big change in surface temperatures between the Equator and the poles.  It is vital for Earth’s health because it keeps Antarctica cool and frozen.  The Antarctic Circumpolar Current, or ACC, is the strongest ocean current on our planet. It extends from the sea surface to the bottom of the ocean, and encircles Antarctica.  The ACC carries an estimated 165 million to 182 million cubic metres of water every second (a unit also called a “Sverdrup”) from west to east, more than 100 times the fl ow of all the rivers on Earth.  t provides the main connection between the Indian, Paci fi c and Atlantic Oceans.  The tightest geographical constriction through which the current fl ows is Drake Passage, where only 800 km separates South America from Antarctica.  Global warming has led to changes in nature of this current. Hence, scientists are studying that how it might affect the world’s climate.
