Forests control drought through

Options

A. Function as water shed
B. Supporting water plants
C. Retention of water and prevention of soil erosion
D. Increasing rainfall

Answer

### Step-by-Step Solution:

1. **Understanding the Role of Forests**:
- Forests play a crucial role in controlling drought conditions through various mechanisms. They help maintain moisture levels in the soil and prevent soil erosion.

2. **Soil Binding**:
- The roots of trees and plants bind the soil together. This binding prevents soil erosion, which is critical because erosion can lead to the loss of nutrients and moisture in the soil.

3. **Absorption of Water**:
- The roots of trees absorb groundwater and moisture present in the soil. This absorption is vital for maintaining the water content in the soil, especially during dry periods.

4. **Water Return to the Atmosphere**:
- The absorbed water is eventually returned to the atmosphere through a process called transpiration. This process involves water traveling from the roots through the plant to the leaves, where it evaporates into the air.

5. **Formation of Clouds**:
- The water vapor released into the atmosphere undergoes condensation, forming clouds. This is a crucial part of the water cycle.

6. **Precipitation**:
- Eventually, the water in the clouds falls back to the ground as precipitation (rain), which replenishes the soil moisture and supports plant growth.

7. **Conclusion on Drought Prevention**:
- By preventing soil erosion and maintaining moisture levels through these processes, forests effectively control drought conditions. Areas with fewer trees are more prone to drought due to the lack of these natural processes.

8. **Correct Answer**:
- The correct option regarding how forests control drought is: **Retention of water and prevention of soil erosion**.
