Condensation near the ground
Fog develops when air having a relatively high humidity comes in contact with a colder surface, often the Earth's surface, and cools to the dew point. Additional cooling leads to condensation and the growth of low-level clouds.

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>.
