Explain the process of how clouds form.

Answer:

Clouds form when water evaporates from Earth's surface and rises into the atmosphere as water vapor. As the warm, moist air rises, it cools. Cooler air cannot hold as much water vapor, so the vapor condenses around tiny particles such as dust or pollen, forming tiny water droplets or ice crystals. When enough of these droplets or crystals gather together, they become visible as a cloud.
