Electricidad: relampagos

The video explains how lightning is a form of static electricity discharge occurring when strong charges develop in storm clouds. Negative charges at the cloud's bottom repel other negative charges and attract positive charges on Earth, leading to electric shocks. Lightning is the movement of charged particles, and its immense electricity heats the air, causing thunder. Lightning is dangerous, killing and injuring people annually. Safety tips include seeking shelter and avoiding open spaces and tall objects during storms.

What causes negative charges to develop at the bottom of a storm cloud?

• The rapid expansion of air

• The attraction of positive charges from the ground

• The presence of tall objects on Earth

• The movement of water and particles within the cloud

How is lightning formed?

• By the movement of charged particles between different charges

• By the reflection of sunlight

• By the collision of two clouds

• By the rapid cooling of air

What is the primary cause of the sound of thunder?

• The collision of clouds

• The rapid expansion of superheated air

• The attraction of positive charges

• The movement of water particles

What should you do if you see lightning and cannot find shelter?

• Stay in open fields

• Seek low spots and avoid open spaces

• Stand near tall objects

• Hold metal objects

Why is it important to wait 30 minutes after the last rumble of thunder before leaving shelter?

• To prevent sunburn

• To avoid getting wet

• To allow the air to cool down

• To ensure the storm has passed
