The correct answer is A. cA air masses are colder than cP air masses.
Explanation:
In geography, air masses refer to uniform bodies of air that have specific characteristics especially in terms of temperature and moisture. This includes different air masses such as the continental arctic masses (cA), the continental polar (cP), the continental tropical (cT), the maritime tropical (mT) and the maritime polar (mP). In the case fo the continental arctic masses (cA) these are extremely cold with a temperature range from -55 to -35 °C also, they are dry and stable, these type of masses are similar to continental polar masses (cP), although these are not as cold or as dry as artic ones as they had a temperature range from -35 to -20 °C. Thus, the correct statement is "cA air masses are colder than cP air masses".
They grow distinct crystal shapes because they have a loot of room and their growth and movement is not restricted, which enables them to form in whichever way they can, which is why they are so distinct.
The United States gets 81% of its total energy from oil, coal, and natural gas, all of which are fossil fuels. We depend on those fuels to heat our homes, run our vehicles, power industry and manufacturing, and provide us with electricity.
