Question 13 Marks

What is cloudburst?

Answer

Sometimes the water coming down from rain clouds does not reach the land in the form of rain. Instead, due to very high temperature near the land, it vaporizes and goes back into the same clouds.
As a result the amount of vapour in those clouds becomes very high.
Due to rapid condensation, it rains suddenly over a specific and small region at a rate of 100 mm per hour or more. This is known as a cloudburst.

Question 23 Marks

What causes lightning?

Answer

Where air and clouds rub against each other in the sky, the upper part of some clouds on the upper side becomes positively charged and the lower sides become negatively charged.
When this negative charge on the bottom of the cloud becomes much larger than the charge on the ground it starts flowing towards the ground in stages.
This happens very fast, in much less than a second and heat, light and sound energy are produced along with the electric current.
