The third and final type of rain, is convection rain

The cloud formations look like a cauliflower.

Convection clouds are formed by bubbles of air rising upwards in the atmosphere.

This happens when the air is heated from below by either warm land or warm sea.

Once the cloud reaches a certain height the temperature cools and condenses the water vapour to produce rain.

This means that convective rain falls over a much smaller area, with clear spells in between, often called sunshine and showers.

In comparison with frontal rain which can last for many hours, convective rain is shorter lived, lasting between 20 minutes and an hour.

Look at all of the pictures in turn. As you hover over each one a blue screen appears with an explanation of what the picture shows. Important words are highlighted. If you are certain that you know about the picture click on it and it will disappear. As you go through all of the pictures you will get rid of all those which you know about and be only left with those you may be unsure of. In some cases you may get rid of all of the pictures in which case you are ready to move on to other activities which will test your knowledge on that particular topic.
