I WONDER - What Is Thunder?

The video explains the relationship between thunder and lightning, highlighting that thunder is the sound produced by a lightning bolt as it travels through the air. The lightning bolt heats and expands the air, creating a rumbling noise known as thunder. Since light travels faster than sound, we see lightning before hearing thunder, even though they occur simultaneously.

What is the relationship between thunder and lightning?

• Thunder always precedes lightning.

• They occur simultaneously but are perceived differently.

• They are unrelated phenomena.

What causes the sound known as thunder?

• The reflection of sound waves in the atmosphere.

How does a lightning bolt affect the air around it?

• It creates a vacuum in the air.

• It heats and expands the air.

• It causes the air to contract.

• It cools the air rapidly.

Why do we see lightning before we hear thunder?

• Because sound travels faster than light.

• Because lightning is brighter than thunder.

• Because light travels faster than sound.

• Because thunder is delayed by atmospheric conditions.

What is the primary reason for the time difference in perceiving lightning and thunder?

• The altitude of the clouds.

• The intensity of the lightning.

• The distance of the storm.

• The speed of light compared to sound.
