How lightning takes place?
Advertisements
उत्तर
-
Lightning is produced by the discharge of electricity from cloud to cloud or from cloud to ground.
-
During thunderstorm, air is moving upward rapidly.
-
This air which moves rapidly carries small ice crystals upward.
-
At the same time, small water drops move downward.
-
When they collide, ice crystals become positively charged and move upward and the water drops become negatively charged and move downward.
-
So the upper part of the cloud is positively charged and the lower part of the cloud is negatively charged.
-
When they come into contact, electrons in the water drops are attracted by the positive charges in the ice crystals. Thus, electricity is generated and lightning is seen.
-
Sometimes the lower part of the cloud which is negatively charged comes into contact with the positive charges accumulated near the mountains, trees, and even people on the earth. This discharge produces a lot of heat and sparks that result in what we see as lightning.
