Burning fossil fuels releases large amounts of what greenhouse gas?
Answer: Carbon dioxide
Bonus fact: CO2 is a major product of hydrocarbon combustion.
Methane is an important greenhouse gas because it absorbs what kind of radiation?
Answer: Infrared radiation
Bonus fact: Methane traps heat by absorbing infrared energy.
Which greenhouse gas is released in large quantities when fossil fuels are burned?
Answer: Carbon dioxide
Bonus fact: CO2 from combustion adds to atmospheric greenhouse warming.
What greenhouse-gas advantage does nuclear power have during electricity generation?
Answer: Very low direct carbon dioxide emissions
Bonus fact: Lifecycle emissions exist, but direct operational emissions are low.
Which gas is a major naturally occurring greenhouse gas?
Answer: Water vapor
Bonus fact: Water vapor contributes strongly to Earth's natural greenhouse effect.
Which greenhouse gas does NASA describe primarily as a feedback because its atmospheric amount responds strongly to temperature changes?
Answer: Water vapor
Bonus fact: More water vapor can amplify an initial warming because water vapor itself absorbs heat radiated by Earth.
