Understanding Lightning and Thunder Concepts

The video explains the process of lightning formation. Inside a thundercloud, hail and snowflakes interact, leading to a charge separation. A conductive air channel, called a leader, forms and connects with the ground, resulting in a lightning bolt. This process transfers significant energy to the ground, creating thunder and enough power to sustain a household for a month.

What happens to snowflakes inside a thundercloud that contributes to lightning formation?

• They fall to the ground.

• They become positively charged.

• They gain a negative charge by losing electrons.

• They evaporate into the air.

What is the role of the leader in the lightning formation process?

• It prevents lightning from reaching the ground.

• It disperses the cloud's energy into the atmosphere.

• It connects the cloud to the ground for electron transfer.

• It creates a path for rain to fall.

How do positive charges from the ground interact with the leader?

• They repel the leader.

• They neutralize the leader.

• They reach up to connect with the leader.

• They have no interaction with the leader.

What is the speed of a lightning bolt as it travels up the leader?

• Half the speed of light

• The speed of sound

• One-third the speed of light

• Twice the speed of light

What causes the sound of thunder?

• The collision of clouds

• The rapid expansion of air due to heat

• The movement of rain

• The reflection of sound waves from the ground

How much energy can a lightning bolt transfer to the ground?

• Enough to power an average American household for over a month

• Enough to power a city for a year

• Enough to power a light bulb for a week

• Enough to power a car for a day
