Which of the following describes an air mass with the symbol ct? a. it is a cold air mass over an ocean c. it is a warm air mass over an ocean b. it is a warm air mass over a continent d. it is a cold air mass over a continent

b. it is a warm air mass over a continent

Explanation:

A symbol cT that stands for an air mass represents a warm air mass over a continent. The 'c' stands for 'continental', while the 'T' stands for 'Tropical', thus it gives us the basic information about the air mass. This type of air masses form deeper into the continents in the tropical regions that are arid or semi-arid. Because there is build of heat at these places, the air becomes very warm, even hot, and once a large air mass forms it starts to move, bringing in hot and very dry weather.

The correct answer is B. it is a warm air mass over a continent

Explanation

An air mass is a portion of the air in the atmosphere characterized by its similar temperature and humidity characteristics. The air masses originate over regions of land or water from which they obtain their characteristics, for this reason when a mass of air is established in a region for several consecutive days it acquires the temperature and humidity of that region.

The air masses are classified according to their origin, in the tropical zones (hot air) or polar (cold air), at the same time, they are classified as continental (dry air) and maritime (humid air).

Therefore we find masses of hot and humid air that originates in the maritime tropical zones (mT), dry hot air masses originated in continental tropical zones (cT), cold and dry air masses, originating in continental polar zones (cP ) and cold and wet air masses originated in polar marine areas (mP). According to the above, the air masses represented by the symbol cT are warm and dry originating in continental tropical areas. So, the correct answer is B. It is a warm air mass over a continent.
