a. cold, polar air
b. a mountain range
c. rising air
d. blocks moisture from the oceans
e. descending air
f. causes high amounts of rainfall
g. causes high amounts of snowfall
h. is part of a cell that originates at the equator

Answer 1

The subtropics at 30 degrees north and south contain deserts primarily due to descending air that blocks moisture from the oceans, leading to arid conditions.

Step-by-step explanation:

The correct sentence using the words provided is: The main reason that the subtropics at 30 degrees north and south of the equator contain deserts is because of descending air that blocks moisture from the oceans. Subtropical deserts like the Sahara and the Namib are very dry, with evaporation typically exceeding precipitation. These areas experience high-pressure conditions with dry air descending at around 30 degrees north and south latitude, leading to extremely arid conditions. This is contrary to the regions affected by rain shadows, where mountain ranges block moisture from the ocean, causing the leeward side to be desert-like.
