How are clouds formed? Explain.

Answer»
  • The process of evaporation followed by condensation causes the formation of clouds. 
  • On a warm day, the sun heats up the water in oceans, seas, rivers, ponds etc. 
  • It helps the water convert to water vapour by the process of evaporation. 
  • When the water vapour rises up into the atmosphere it becomes cooler. 
  • When water vapour reaches a higher level, it condenses due to contact with cool air and forms small drops or water droplets. 
  • These tiny droplets remain floating in the air at higher levels of the atmosphere and appear as clouds.
