Match the column and complete the chain:

(A) Cirrus – (ii) Higher altitude – (d) Snow flake clouds

Explanation- Cirrus is a high-level cloud with an altitude of 7000 to 14000 metres. They are called snow flake clouds because they are composed of ice particles.

(B) Cumulonimbus – (i) Vertical extent in the sky- (a) roaring clouds

Explanation- Cumulonimbus are mountain-like huge vertical clouds which are formed as a result of strong upward water vapour currents in the atmosphere.

They are known as roaring clouds as they are responsible for thunderstorms and lightening.

(C) Nimbostratus – (iv) Low altitude – (c) continuous rain.

Explanation- Nimbostratus clouds are low-level clouds with an altitude of fewer than 2000 metres. They are dark and have dense layers which block the sun and hence cause continuous and persistent rains.

(D) Alto-cumulus – (iii) Medium altitude – (b) floating clouds

Explanation- Alto-cumulus is a mid-level cloud with an altitude of about 2000 to 7000 metres. They contain water droplets and appear puffy. Due to condensation, the clouds become light weight and float in the air. Hence they are called floating clouds.
