Question

How does a thunderstorm develop?

Accepted Answer

A storm with thunder and lightning is called a thunderstorm. It accompanies by heavy rainfall or hail. A thunderstorm is formed in the following way:

1. The water vapour present in the rising air cools and condenses to form a cloud.

2. This cloud grows upwards into areas where the temperature is close to the freezing point of water. The cloud becomes charged with positive and negative charges.

3. When a large amount of opposite electric charges build up in the cloud, a tremendous amount of electric current passes through the air into the cloud which produces a big electric spark within the cloud.

4. This electric spark is lightning. The spark of lightning heats the nearby air too much. This extremely hot air expands explosively causing a loud sound called thunder.

5. When electric charges from the bottom of the electrically charged cloud flow down through the air to the ground, then we see the flash of lightning coming towards the earth.

6. The big water drops in the thundercloud fall to the earth as heavy rain (or hail). In this way, a thunderstorm brings strong winds, thunder, lightning, and heavy rains (or hail).
