Lightning can cause significant damage due to its extreme heat, which is five times hotter than the sun's surface. To protect buildings, metal rods known as lightning conductors are installed. These conductors safely channel the lightning's energy to the ground, preventing it from passing through the building.

What is one of the most significant characteristics of lightning?

• It is cooler than the surface of the sun.

• It is harmless to buildings.

• It can cause minimal damage.

• It is five times hotter than the surface of the sun.

What is the primary purpose of a lightning conductor?

• To protect the building from lightning strikes.

• To increase the building's height.

• To enhance the building's appearance.

• To attract more lightning to the building.

How do lightning conductors protect buildings?

• By preventing lightning from striking the area.

• By redirecting the lightning safely to the ground.

• By absorbing the lightning into the building.

• By storing the lightning energy for later use.

What happens when lightning strikes a building with a conductor?

• The building is destroyed.

• The lightning is safely directed to the ground.

• The building absorbs the lightning.

• The lightning is deflected back into the sky.

Why are metal rods used in lightning conductors?

• Because they are lightweight.

• Because they are good conductors of electricity.

• Because they are poor conductors of electricity.

• Because they are decorative.
