From the statements given below identify the causes of soil erosion
I.strong winds
II.contour ploughing
III.deforestation
IV.step farming
V.improper cultivation practices

Options

A. I,II,IV and V
B. II and IV
C. I,III and V
D. II,IV and V

Answer

To identify the causes of soil erosion from the given statements, we will analyze each option provided:

1. **Strong Winds**: Strong winds can displace soil particles, leading to soil erosion. This is a recognized cause of soil erosion.

2. **Contour Ploughing**: Contour ploughing is an agricultural practice that involves ploughing along the contours of the land. This method helps to reduce soil erosion by creating natural barriers that slow down water runoff. Therefore, this is not a cause of soil erosion.

3. **Deforestation**: Deforestation involves the removal of trees, which play a crucial role in holding the soil together. When trees are removed, the soil becomes more vulnerable to erosion. Thus, deforestation is a cause of soil erosion.

4. **Step Farming**: Step farming, or terrace farming, is a method used to cultivate sloped land. It helps to reduce soil erosion by creating flat areas that slow down water runoff. Therefore, this is not a cause of soil erosion.

5. **Improper Cultivation Practices**: Practices such as overgrazing, monoculture, and poor land management can lead to soil degradation and erosion. Thus, improper cultivation practices are indeed a cause of soil erosion.

### Summary of Causes of Soil Erosion:
- **Causes**:
- Strong Winds (I)
- Deforestation (III)
- Improper Cultivation Practices (V)
- **Not Causes**:
- Contour Ploughing (II)
- Step Farming (IV)

### Final Answer:
The causes of soil erosion from the statements are I (Strong Winds), III (Deforestation), and V (Improper Cultivation Practices).
