During which part of the water cycle does a cloud form?
A
Evaporation
B
Precipitation
C
condensation
D
Run off
Explanation: 

Detailed explanation-1: -Condensation is the process by which water vapor in the air is changed into liquid water; it’s the opposite of evaporation. Condensation is crucial to the water cycle because it is responsible for the formation of clouds.

Detailed explanation-2: -Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. For this to happen, the parcel of air must be saturated, i.e. unable to hold all the water it contains in vapor form, so it starts to condense into a liquid or solid form.

Detailed explanation-3: -Step 2: condensation As water vaporizes into water vapor, it rises up in the atmosphere. At high altitudes the water vapor changes into very tiny particles of ice /water droplets because of low temperature. This process is called condensation. These particles come close together and form clouds and fogs in the sky.

Detailed explanation-4: -Once the parcel reaches saturation temperature (100% relative humidity), water vapor will condense onto the cloud condensation nuclei, resulting in the formation of a cloud droplet.
