Dust particles along with water vapour present in the atmophere help in the formation of clouds.

Explanation

### Step-by-Step Solution:

1. **Understanding the Components**:
- The atmosphere contains tiny particles, such as dust, and water vapor.
- These components are essential for cloud formation.

2. **Role of Water Vapor**:
- Water vapor is present in the air and is a gaseous form of water.
- When the air cools, this water vapor can condense.

3. **Condensation Process**:
- The water vapor condenses into liquid water droplets.
- This condensation occurs on the surfaces of dust particles present in the atmosphere.

4. **Formation of Water Droplets**:
- As more water vapor condenses onto these dust particles, they form tiny water droplets.
- These droplets cluster together.

5. **Visible Cloud Formation**:
- When enough water droplets accumulate, they become visible as a cloud.
- Thus, the presence of dust particles and water vapor is crucial for cloud formation.

6. **Conclusion**:
- Therefore, the statement that "Dust particles along with water vapor present in the atmosphere help in the formation of clouds" is true.
