• a cloudy day with little wind

• a clear day with little wind

How does fire help the balloon fly?

How does letting out hot air make the balloon sink?

• Since there is more hot air, the balloon can keep the same weight in the air.

• Since there is less hot air, the balloon cannot keep the same weight in the air.

• Since there is less hot air, it doesn't matter what happens to the balloon.

• Since there is more hot air, the balloon will land fine.

What causes pilots to always check the weather?
