If there were no deserts, all of the life (plants and animals) that are adapted to a desert environment would either 1) die, or 2) adapt to a different environment in order to survive. Answer 2: Deserts form because of the location of mountains and because of the way air circulates around the planet.

What causes a desert to form?

Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Rocks are smoothed down, and the wind sorts sand into uniform deposits. The grains end up as level sheets of sand or are piled high in billowing sand dunes.
