Look at figure 3.8 first. Now go out of the classroom in the ground. Observe the clouds in the sky. Discuss the following points in the class and write answers in your notebook.

• What was the colour and size of the clouds?

• What type of clouds did you observe? (Take help from fig 3.8)

• Can these clouds bring rain? Give reasons.

• The colour of the clouds is white and they are not huge in size.

• The altitude is less, so I think they might be cumulonimbus clouds or cumulus clouds

• Yes, these clouds can bring continuous rainfall. The low altitude clouds consist of five types of clouds. They are also called as Strato-cumulus clouds. They have layers. Their colour is white to earthy. Round clusters of clouds can be here. Stratus clouds also have layers. They are ash coloured and their base is uniform. Nimbo-stratus has thick layers. They are grey-ash in colour and cause continuous rainfall and even snowfall.
