In which layer of the atmosphere is the protective ozone layer located?

The stratosphere, approximately 10 to 30 miles above Earth's surface.

What harmful type of solar radiation does the stratospheric ozone layer primarily absorb?

Ultraviolet (UV-B) radiation from the sun.

What is the chemical formula for ozone?

O3 — ozone consists of three oxygen atoms bonded together.

Which atom released from CFCs is primarily responsible for destroying stratospheric ozone?

Chlorine (Cl) atoms catalytically destroy ozone molecules in the stratosphere.

What is the Ozone Depletion Potential (ODP) of CFC-12?

CFC-12 has an ODP of 1.0, which serves as the baseline reference value.
