Infrared and UV-B
What is the role of tropospheric ozone?
It is a respiratory irritant and damages plant tissue.
It absorbs UV radiation.
It provides oxygen for breathing.
It cools the Earth's surface.
What does UV-C radiation do to O₂ molecules?
Combines them into ozone (O₃)
Breaks them into two free oxygen atoms
Converts them into carbon dioxide
Turns them into water molecules
What is the significance of the continued formation and breakdown of O₃ in the stratosphere?
It releases harmful gases into the atmosphere
It absorbs all UV-C and much UV-B radiation, protecting organisms on Earth
It causes global warming
It depletes the oxygen supply on Earth
What are CFCs primarily used as?

10,000
100,000
1,000,000
What is the role of chlorine atoms in ozone depletion?
They create ozone
They break O₃ down into O₂
They stabilize O₃
They convert O₂ into O₃
What was the purpose of the Montreal Protocol of 1987?
To increase the production of CFCs
To phase CFCs out of production
To ban the use of HCFCs
To promote the use of aerosols
What are HFOs?
HFCs with C-C double bonds
HCFCs with C-C double bonds

Gamma rays
How do greenhouse gases interact with infrared radiation?
They absorb it and radiate it both out into space and back toward Earth
They completely block it from escaping into space
They reflect it back into space without absorption
They convert it into visible light
