Question

Consider the following statements:
I. Lightning occurs between the Earth and the clouds
II. Lightning occurs between the same clouds
III. Lightning occurs due to the discharge between charged clouds and the Earth
Among the given statements,

• A. only statement I is correct
• B. statements II and III are correct
• C. statements I and III are correct
• D. only statement II is correct

Answer 1

The correct option is C

statements I and III are correct

During lightning, negative and positive charges of the lower and upper parts of different clouds conduct each other. The negatively charged lower part of the cloud conducts with the positively charged Earth. Lightning occurs due to a discharge between different clouds. It does not occur due to a discharge between the upper and lower parts of the same cloud. Hence, only statement II is incorrect.
