Answer:
A. Weather and Erosion
Step-by-step 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.
