Define air mass. A: a large body of air. The entire air mass has the same temperature and moisture throughout. B: cooler temperature causing more molecules to be in an area and be more tightly packed. C: Warmer temperatures cause less molecules to be in an area and results in less packed/more space between molecules. D: The weight of all the air molecules in the atmosphere pressing Down on earth.
In meteorology, an air mass is a volume of air defined by its temperature and water vapor content.
A: a large body of air. The entire air mass has the same temperature and moisture throughout. Hope this helps
