Which of the following statements are "true"
Water vapour condenses to forms tiny droplets of water in the upper layers of air where it is cooler.

Answer

**Step-by-Step Solution:**

1. **Understanding the Terms:**
- The question refers to the process of condensation. Condensation is the process where a gas changes into a liquid.

2. **Identifying the Gas and Liquid:**
- In this context, the gas is water vapor, and the liquid is water.

3. **Describing the Process:**
- Water vapor in the air rises to the upper layers where the temperature is cooler.

4. **Condensation of Water Vapor:**
- As the water vapor cools, it condenses into tiny droplets of water.

5. **Formation of Clouds:**
- These tiny droplets of water gather together and form clouds in the upper layers of the atmosphere.

6. **Conclusion:**
- Since the statement describes the process of water vapor condensing into droplets in cooler air and forming clouds accurately, we conclude that the statement is true.

**Final Answer:**
- The statement "Water vapor condenses to form tiny droplets of water in the upper layers of air where it is cooler" is **true**.
