Understanding Lightning and Static Electricity

The video explains how lightning is formed when warm and cold air in clouds mix, creating a static electric charge. This charge can discharge to another cloud or the ground. The video then demonstrates how to create a similar static charge at home using socks and a carpet. By rubbing socks on a carpet, you can build up static electricity, which can discharge when touching a metal object, creating a small spark similar to lightning.

What natural phenomenon is being compared to a home experiment in the video?

• Lightning

• Tornado

• Earthquake

• Rainfall

What causes the buildup of static electric charge in clouds?

• The movement of birds

• The rotation of the Earth

• The presence of rain

• The mixing of warm and cold air

When does a lightning strike occur according to the video?

• When the wind is blowing hard

• When the clouds are full of rain

• When the positive charge in clouds is strong enough

• When the sun is shining brightly

What household items are used to demonstrate static electricity in the video?

• A balloon and a wall

• A comb and paper

• Socks and a carpet

• A spoon and a glass

What happens when you touch a metal doorknob after building up static electricity?

• You feel a cold sensation

• You see a spark

• You smell something burning

• You hear a loud noise
