Arctic air masses are extremely cold because during the winter these areas receive no solar radiation but continue to radiate thermal energy causing the air masses to become extremely cold.

question 13 options:
a) true
b) false

The given statement is true.

Option: (a)

Explanation:

The 'amount of insolation' received in the areas constituting the arctic circle and further north is the least on the Earth. The heat received by these areas is way too less compared to the heat radiated by these areas. It is because of this attribute, the air masses originating in these areas are extremely dry and cold. The reason behind these areas receiving the lowest insolation is the 'axial tilt of the Earth'.
