Question 1:

Which of the following atmospheric circulation cells is responsible for the formation of the trade winds?

Explanation: The formation of the trade winds is primarily associated with the Hadley cell, which is responsible for the atmospheric circulation near the equator. In the Hadley cell, warm air rises at the equator, moves towards the poles at high altitudes, and then sinks around 30 degrees latitude, resulting in the trade winds. Therefore, the correct answer is C) Hadley cell.

Question 2:

Which weather phenomenon is associated with the interaction between warm and cold air masses?

Explanation: The interaction between warm and cold air masses is associated with the formation of fronts. A front is a boundary where two air masses with different temperatures and densities meet. This interaction can lead to the formation of various weather phenomena, including thunderstorms and tornadoes. Therefore, the correct answer is D) Fronts.

Question 3:

Which of the following pressure systems is associated with clear skies and calm weather?

Explanation: High-pressure systems are associated with clear skies and calm weather conditions. In a high-pressure system, air descends, leading to the suppression of cloud formation and the inhibition of precipitation. Low-pressure systems, on the other hand, are associated with unsettled weather and the potential for stormy conditions. Therefore, the correct answer is B) High-pressure system.

Question 4:

Which global wind belt is responsible for the prevailing westerlies in the middle latitudes?

Explanation: The prevailing westerlies in the middle latitudes are associated with the Subtropical jet stream. The Subtropical jet stream is a fast-moving ribbon of air located at high altitudes, around 30-35 degrees latitude. It influences the movement of weather systems and contributes to the west-to-east flow of the prevailing westerlies. Therefore, the correct answer is C) Subtropical jet stream.

Question 5:

Which atmospheric circulation cell is responsible for the formation of the polar easterlies?

Explanation: The formation of the polar easterlies is primarily associated with the Polar cell. In the Polar cell, cold air sinks at the poles and moves towards the lower latitudes, forming the polar easterlies. The Ferrel cell, on the other hand, is responsible for the formation of the prevailing westerlies. Therefore, the correct answer is A) Polar cell.
