Deforestation may reduce the chances of :

Options

A. erosion of surface soil
B. frequent landslides
C. rainfall
D. frequent cyclones

Explanation

To solve the question regarding the effects of deforestation, we need to analyze the options provided and understand how deforestation impacts various environmental factors.

### Step-by-Step Solution:

1. **Understanding Deforestation**:
- Deforestation refers to the large-scale removal of trees and forests. This can lead to various ecological consequences.

2. **Analyzing the Options**:
- The question states that deforestation may reduce the chances of certain environmental factors. We need to evaluate each option provided.

3. **Option 1: Erosion of the Surface**:
- Deforestation can actually increase soil erosion because trees help hold the soil together with their roots. Therefore, this option does not fit as deforestation reduces the chances of erosion.

4. **Option 2: Frequent Landslides**:
- Similar to erosion, trees help stabilize the soil. Without them, the risk of landslides increases. Thus, deforestation does not reduce the chances of landslides; it increases them.

5. **Option 3: Loss of Species**:
- Deforestation leads to habitat destruction, which can reduce the chances of species survival. However, this option is not directly related to the question about reducing chances.

6. **Option 4: Rainfall**:
- Trees play a crucial role in the water cycle by facilitating the process of transpiration, which contributes to cloud formation and rainfall. Deforestation can lead to a decrease in rainfall, thus reducing the chances of adequate precipitation.

7. **Conclusion**:
- Based on the analysis, the correct answer to the question is that deforestation may reduce the chances of **rainfall**.

### Final Answer:
Deforestation may reduce the chances of **rainfall**.
