How are clouds formed???

Riya Suyal 6 years, 2 months ago

At sufficient height the air became so cool that the water present in air condenses to form tiny drops of water called droplets these tiny drops of water appear as clouds .

2Thank You

Yogita Ingle 6 years, 2 months ago

Clouds are formed by the process of evaporation and condensation
Water evaporates from water bodies and rises up in the air. This air also gets heated.
Hot air carrying water vapour rises up. It cools down as it goes up.
Cooling causes condensation of water vapour, which leads to the formation of tiny droplets.
Tiny droplets grow bigger and heavy by more condensation which ultimately leads to the formation of clouds.

Protein molecule is made of a large number of smaller molecules called amino acid. The daily requirement of protein for adults is 1 gram per kilogram of the body weight. When the body is building new tissue, more proteins are required, so growing children and pregnant lady need more protein.

Take a Rubber pipe and stretch it straight and try to see the flame of a candle.
You are able to see the flame through the pipe.

Now bend the same pipe and place one end of the pipe towards the flame and try to see the flame from the other end.

You cannot see the flame as it is blocked.

From this we can say that the light travells in straight paths.

Explain the adaptation of animals to live in mountain region.

Posted by Priyanshi Negi 6 years, 2 months ago

CBSE > Class 06 > Science (OLD)

1 answers

Yogita Ingle 6 years, 2 months ago

The mountain habitat is very cold and snowfall takes place in winters in some areas.

The trees of the mountain habitat are cone-shaped. The leaves of such trees are needle-shaped. The needle-shape of leaves helps in preventing accumulation of snow on the leaves and thus they are not damaged due to snow.

Animals in the mountain habitat have thick coat of fur. This helps in keeping them warm during very cold winters. The mountain goats have strong hooves which help them in running along the mountain slopes. Yak and snow leopards are common examples of animals in the mountain habitat.
