(A) Cloud formation:

• The water cycle involves the step of cloud formation.
• The air containing water is heated up by the sun and being lighter rises high in the sky.
• As air rises to high altitude, the water vapor present in it gets cooled.
• The cold water vapor condenses to form tiny droplets of water.
• These tiny droplets of water form clouds in the sky.
