Answer:
C. A mass of air that is similar in temperature and humidity
Explanation:
An "air mass" refers to a big volume of air that is characterized by having similar or uniform "temperature" and "humidity"<em> (moisture).</em> They come from different source regions, thus they are classified accordingly.
The<em> "cold air masses"</em> come from the <u>polar area</u>s while the<em> "warm air masses"</em> come from the<u> tropical areas.</u> An air mass may cause a storm, for example, when an air mass moves to a new region and confronts another air mass there with a<em> different humidity and temperature</em>.
A steep pressure gradient ( where isobars<span> are </span>close together<span>) </span>indicate<span> higher winds, a less steep pressure gradient (where </span>isobars<span> are farther apart) </span>indicate<span> slower air movement. ... Be able to interpret a </span>weather map<span> that shows the distribution of air pressure and wind flags.</span>
