Pruitt lives in a city that is typically dominated by a maritime tropical air mass. After listening to the weather update, he le
arns that a maritime polar air mass is approaching his city. Which statement explains this movement of air? A.
Air masses move from west to east in the Northern Hemisphere.
B.
Air masses move from colder areas to warmer areas.
C.
Air masses move from high-pressure areas to low-pressure areas.
D.
Two air masses merge into one and share the properties of both original air masses.
The masses of air move from the areas of high pressure to the areas of low pressure. Pruitt's city must be situated more or less within the equator for it to be dominated by maritime tropical air mass. This area gets adequate sunlight all throughout the year because of the comparative position of the Sun.
Therefore, its atmosphere is usually more heated in comparison to that of the Polar Regions. The air in the tropic regions turns less dense and elevates into the upper atmosphere. The cooler and denser maritime polar air mass from the poles moves in to substitute the elevating air in the tropics, thus, developing incoming cooler winds.
This is the reason for the creation of the trade winds across the globe and distributing energy around the planet to a more or less homeostatic level.
