Observe the sky and identify the clouds based on their forms.
When condensation of water vapour happens around the dust particles present in the atmosphere, clouds are formed. Water droplets which formed are less than 0.001 cm in dimension. Clouds are classified based on their height and form which are as follows:
• Cirrus clouds – this type of clouds is present in the upper atmosphere when the weather is clear. These are the feather-like clouds.
• Stratus Clouds – this type of clouds is present in the lower part of the sky which is in a thick layer.
• Cumulus clouds – this type of clouds looks like the huge cotton bundles. These are formed by the strong convection currents and have large vertical coverage.
• Nimbus clouds – this type of clouds appear as dark rain clouds present in the lower atmosphere. Nimbus clouds didn’t allow sunlight to pass through them as the concentration of water droplets is thick.
Clouds appear in different forms at the same time, for example - cumulus and nimbus clouds appear together is termed as cumulo-nimbus clouds.
