Q

How does rain occur?
(Dew Points, Cold Air, Hot Air)

A
  • It occurs when warm moist air cools and condenses into water droplets.
  • Warm air can hold more water than cold air
  • As the warm air continues to rise and cools, it will eventually reach the dew point.
  • When the warm air cools above its dew point, the water vapour, water in a gaseous form, condenses into a liquid and it rains
