With reference to the continent of 'Antarctica' which of the following statements are correct ? 1. It is larger than Europe in terms of area. 2. It has the highest average elevation as compared to all other continents. 3. Mt. Ross is the highest peak of this continent. 4. Waters of the Southern Ocean (West Wind Drift) move in an anticlockwise direction around it. Select the answer using the code given below :
- A.1 and 2 only
- B.1 and 3 only
- C.1, 2 and 3
- D.2, 3 and 4
Correct answer
Explanation
The correct answer is A, 1 and 2 only. Antarctica is bigger than Europe and, because of its thick ice sheet, it stands higher on average than any other continent.
Antarctica covers about 14 million square kilometres, against roughly 10 million for Europe, making it the fifth largest continent. Its ice sheet, more than two kilometres thick on average, gives it a mean elevation of about 2,500 metres, the highest of all continents. Its highest peak is Mount Vinson in the Vinson Massif of the Ellsworth Mountains, about 4,892 metres high. The Antarctic Circumpolar Current, or West Wind Drift, flows from west to east around the continent, which looks clockwise when seen from above the South Pole.
B is wrong because statement 3 is false; Mount Vinson, not Mount Ross, is the highest peak. C is wrong for the same reason. D is wrong because statements 3 and 4 are both false and it leaves out the true statement 1.
Exam tip: Antarctica: highest average elevation, highest peak Vinson Massif, West Wind Drift flows west to east (clockwise seen from the South Pole).
