Question

Conditions Necessary for Precipitation
Precipitated moisture falling on the ground
depends on the following conditions :
1. The air must be saturated.
2. The temperature at which condensation takes
place, must be present.
3. The air must contain small particles of matter
such as dust around which droplets form.
4. The air must be cooled below its dew point.​

Answer 1

Particles of dust or smoke in the atmosphere are essential for precipitation. These particles, called “condensation nuclei,” provide a surface for water vapor to condense upon. This helps water droplets gather together and become large enough to fall to the Earth.
