Question

12. Which physical process contributed to making desert regions?

Answer 1

Answer:

A. Weather and Erosion

Explanation:

The weather and erosion are the main physical processes that contributed to making desert regions in the world.

• Weather is the atmospheric condition at a particular time.
• Erosion is the removal of the top layer of the soil.

The weather over an extended period of time is known as the climate.

• A desert is an arid region with no vegetation and precipitation.
• This is as a result of the atmospheric condition over a desert.

Constant removal of the topsoil on which plants can easily obtain nutrients can also lead to desertification. Such an environment will not be able to support the growth of plants.
