Key Topics to Revise

1

Water Vapour and Humidity

  • Water vapour varies from zero to four per cent by volume of the atmosphere.
  • Water in the atmosphere exists in three forms: gaseous, liquid, and solid.
  • Moisture enters the atmosphere through evaporation from water bodies and transpiration from plants.
2

Evaporation and Condensation

  • Evaporation changes water from liquid to gaseous state.
  • Heat is the main cause of evaporation.
  • Latent heat of vaporisation is the heat needed to convert a unit mass of liquid into vapour without a change in temperature.
3

Dew, Frost, Fog, Mist, and Smog

  • After condensation, moisture may appear as dew, frost, fog, or clouds.
  • Dew forms as water droplets on cooler surfaces of solid objects such as stones, grass, and leaves.
  • For dew formation, the dew point must be above the freezing point.
4

Clouds

  • Clouds are masses of minute water droplets or tiny ice crystals formed by condensation in free air at considerable heights.
  • Clouds are classified into four basic types: cirrus, cumulus, stratus, and nimbus.
  • Cirrus clouds form at high altitudes between 8,000 m and 12,000 m.
