Q.

What is a ‘tornado’?
Explanation:

ANS. (B) 
A tornado is a closed low pressure circulation which is marked by a violently rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. Low-pressure systems form under areas of wind divergence which occur in upper levels of the troposphere. The formation process of a low-pressure area is known as cyclogenesis.
