Explanation:

Lightening occurs when two oppositely charged ions present in  clouds come in contact with each other that cause electric spark .

Explanation:

Lightening, storms and wind occurs in cooperatively smaller area and destructive on the other hand earthquake occurs over large as it includes one of the tectonic plate of which earth is made area and most destructive in terms of loss of life and property.

Explanation:
