Which major geographic factor dominates nations in the region of North Africa and Southwest Asia?

A collection of vast deserts

Explanation:

Southwest Asia and North Africa have a very dry and hot climate, with little to no precipitation. This is why in this area there are many deserts. The land is flat and the air is dry.

In North Africa, there is the Sahara desert, the largest hot desert in the world. The valley of the Nile and areas around the coast are the only regions not covered in it. Otherwise, it passes through all the northern African countries.

Southwest Asia (also known as Arabian Peninsula and the Middle East) is dominated by the Arabian desert. It is the second-largest desert in the world, dominating Saudi Arabia.
