Detailed explanation-1: -Plants thrive off the Nitrates that are formed when lightning strikes. In a thunderstorm, lightning helps to fertilise soil by causing nitrogen molecules in the air to break apart due to the energy created. These unstable single nitrogen molecules then form bonds with oxygen in the air to form nitrogen oxide.
Detailed explanation-2: -Thunderstorms help transfer the negative charges back to earth (lightning is generally negatively charged). Without thunderstorms and lightning, the earth-atmosphere electrical balance would disappear in five minutes! We aren’t really sure what would happen if this balance wasn’t maintained.
Detailed explanation-3: -Researchers believe that plants can detect electricity that accompanies a storm. This electricity allows a plant’s metabolism ‘to shift into high gear’, ready to use the expected downpour for a spurt in growth.
Detailed explanation-4: -When the attraction becomes too strong, the positive and negative charges come together, or discharge, to balance the difference in a flash of lightning (sometimes known as a lightning strike or lightning bolt). The rapid expansion and heating of air caused by lightning produces the accompanying loud clap of thunder.
