Q7 (CAPF/2014) Geography › World Physical Geography › Atmospheric pressure winds Answer Verified

Statement I : Roaring Forties are strong Westerly winds found in the Southern Hemisphere, generally between the latitudes of 40° and 50° Statement I : The strong East to West air currents are caused by the combination of air being displaced from the Equator towards the South Pole and the Earth’s rotation and there are few landmasses to serve as wind breaks

Result
Your answer: —  ·  Correct: C
Explanation

The correct answer is Option 3 because Statement I is factually accurate, while Statement II contains a fundamental geographical error regarding wind direction.

Statement I is true: The "Roaring Forties" refer to the powerful permanent winds found in the Southern Hemisphere between 40° and 50° latitudes. These are Westerlies, meaning they blow from the West to the East.

Statement II is false: While it correctly identifies the causes of these winds—atmospheric circulation (equator to pole) and the Coriolis effect (Earth's rotation)—it incorrectly describes the direction as "East to West." Westerlies, by definition, move from West to East. Additionally, while the lack of landmasses in the Southern Hemisphere allows these winds to gain immense speed, the directional description in the statement is scientifically incorrect, making the entire statement false.

In summary, the Roaring Forties are West-to-East air currents, contradicting the "East to West" claim in Statement II.
