Water in the atmosphere Chapter 12

What is water vapour? Water vapour is a gas. The amount of water vapour in the air is called Humidity. The highest amount of water vapour in the air is 100% Warm air can hold more water vapour than cold air. When air can hold no more water vapour it is Saturated. The amount of water vapour in the air is measured as RH=Relative Humidity.

Name the four stages of the water cycle? What is water vapour? Name the three main types of cloud and give one main detail of each? Name each type of rain. Draw a diagram for each and explain why each occurs?
