Question

what is an air mass? a large body of air with roughly the same temperature and humidity. any body of air. any body of air that covers at least one square meter. any body of air that covers at least one square mile. rewatch

Explanation:

An air mass is defined as a large body of air that has relatively uniform temperature and humidity characteristics. The other options are incorrect. "Any body of air" is too general as it doesn't mention the key aspect of uniformity. The options about covering a specific area (one square meter or one square mile) are also wrong as the definition is about temperature and humidity uniformity rather than a specific size in terms of area.

Answer:

A. A large body of air with roughly the same temperature and humidity.
