Which of the following promotes soil erosion?

Options

A. Over-grazing
B. Terrace farming
C. Sea breeze
D. Conservation tillage

Explanation

**Step-by-Step Solution:**

1. **Understanding Soil Erosion**:
- Soil erosion is the process where the top layer of soil is removed or carried away by physical forces such as wind or water. This can lead to loss of fertile land and can be detrimental to agriculture.

2. **Identifying Activities that Promote Soil Erosion**:
- We need to analyze the given options to determine which one promotes soil erosion.

3. **Evaluating Each Option**:
- **Overgrazing**: This occurs when livestock graze on the same land repeatedly. They eat the grass and roots, which can lead to the topsoil being exposed and more susceptible to erosion by wind and water. This is a human activity that promotes soil erosion.
- **Terrace Farming**: This is a method of farming on the slopes of hills and mountains, which is designed to reduce soil erosion by creating flat areas for crops. This does not promote soil erosion.
- **Sea Breeze**: This refers to winds that blow from the sea to the land. It is a natural phenomenon and does not promote soil erosion.
- **Conservation Tillage**: This is a farming practice that minimizes soil disturbance and helps maintain soil structure, which actually helps prevent soil erosion.

4. **Conclusion**:
- Among the options provided, **overgrazing** is the only activity that promotes soil erosion. Therefore, the correct answer is **Overgrazing**.

**Final Answer**: Overgrazing promotes soil erosion.
