Condensation
Explanation:
Condensation is a term that describes the collection of water vapor in the atmosphere into clouds.
Condensation is a phase change process that is a key component of the hydrologic cycle in which water moves in different forms in nature.
- It occurs when tiny particles suspended in the atmosphere helps to aggregate vapor.
- As the hot vapor rises from the surface, the temperature decreases up into the atmosphere.
- When it comes in contact with suspended dust or some other particles, it loses its energy and settles on the dust.
- When they aggregate, they form the clouds we see.
