Q131 (IAS/2006) Geography › World Physical Geography › Atmospheric pressure winds Answer Verified

Consider the following statements: I. Length of a terrestrial mile is lesser than that of a nautical mile. II. Harmattan is a dusty land-wind of the East African Coast. III. Greece and Albania from a part of the Iberian Peninsula. Which of the statements given above is/are correct?

Result
Your answer: —  Â·  Correct: D
Explanation

Only statement I is correct. I is true because a statute (terrestrial) mile is about 1.6 km while a nautical mile is defined as about 1.852 km, so the terrestrial mile is shorter [1]. II is false: the Harmattan is a dry, dusty wind associated with the Sahara and affects West African coasts and the Gulf of Guinea region; Sahara dust is known to be transported long distances, so labeling it as an East African coast wind is incorrect [2]. III is false: Greece and Albania are part of the Balkan Peninsula, not the Iberian Peninsula (which comprises Spain and Portugal).
