Question

8. What type of air masses form over land in polar regions?

cold and dry air masses
warm and dry air masses
cold and wet air masses
warm and wet air masses

Answer 1

Air masses that form over land in polar regions are generally cold and dry due to low temperatures and limited moisture, as well as conditions like the polar vortex that isolate the air mass.

Step-by-step explanation:

The type of air masses that form over land in polar regions are typically cold and dry air masses. This is due to the low temperatures and limited moisture sources in polar areas. For instance, in Antarctica, the formation of a "polar vortex" contributes to the isolation and stagnation of the air mass above the continent, leading to very dry conditions. Moreover, due to the high latitude, the low angle of sunlight provides less energy for evaporation, contributing further to the dryness of the air. Thus, the correct choice from the options would be cold and dry air masses.
