How does the ozone layer protect the earth?

• Prevents oxygen molecules from leaving our atmosphere.

• Prevents Hydrochlorofluorocarbon molecules from leaving the atmosphere.

• Protects the earth from ionizing radiation from the sun.

• Protects the earth from ultraviolet radiation from the sun.

When a chlorine atom steals an oxygen atom, it forms a new molecule called

• Chlorine Trioxide

• Chlorine Dioxide

• Chlorine Monoxide

• Chlorine Monostate

How do chlorine atoms come free of their refrigerant bonds?

• When they collide with oxygen atoms, their bond is broken.

• High energy ultraviolet rays from the sun breaks their bond.

• Subzero temperatures break their bonds

• Earth's magnetic field breaks their bond.
