How are clouds formed? Classify them.
उत्तर
Cloud is a mass of minute water droplets or tiny crystals of ice formed by the condensation of the water vapour in free air at considerable elevations. As the clouds are formed at some height over the surface of the earth, they take various shapes. According to their height, expanse, density, and transparency or opaqueness clouds are grouped under four types :
- cirrus
- cumulus
- stratus
- nimbus
