Answer:
An air mass forms when air stays over an area for a while or moves slowly over a area - true.
Air masses that form over over land are moist - false.
Air masses that form over tropical regions are warm. - true.
Polar air masses that form over warm regions.- false.
A warm air mass that forms over the Caribbean Sea is a maritime tropical air mass- True.
Air masses that form over dry land are tropical air masses. - False.
Step-by-step explanation:
We can say that air masses are large volumes of air that have homogeneous and relatively stable temperature, pressure and humidity and that move slowly over a region, influencing weather conditions for a certain period of time. They can form in large volumes of water or land. When the air mass forms on land it is quite dry, however the air mass that forms in water is quite moist.
Tropical air masses are those that form in intermediate latitude regions, close to the equator and therefore are warmer, have high temperatures and low pressure, unlike polar air masses that form in high latitude regions , near the poles. A hot air mass that we can mention is the one that forms in the Caribbean Sea, which is a tropical maritime air mass.
