Formation Of Clouds And Rain

• The Sun heats up the surface of the Earth.
• Water from land, seas, lakes and rivers evaporates to form water vapour in the air.
• Water vapour rises, meets the cool air above and condenses.
• Water droplets are formed.
• These water droplets come together to form clouds.
• When more water vapour condenses, the water droplets join to form bigger and heavier clouds.
• These water droplets will fall onto Earth as rain.
• Rain will return to land, rivers, lakes and seas. 
• This process repeats and is known as the water cycle.
• The process ensures that the total volume of water on Earth is constant.
