Question

Which option describes how CFCpollutants harm the environment?

CFCsfrom cleaning and cooling materials mix with water molecules and cause acid rain.

CFCsfrom non-aerosol spray cans move directly to the lower atmosphere, causing solar radiation that harms Earth’s resources.

CFCsfrom cleaning and cooling materials combine with other molecules in the air, harming Earth’s protective ozone layer.

CFCsfrom auto emissions enter rivers through runoff and waste water, harming Earth’s fresh water resources.

Answer 1

Answer:

The answer is C. CFCsfrom cleaning and cooling materials combine with other molecules in the air, harming Earth’s protective ozone layer.

Explanation:

Chlorofluorocarbonsand (CFCs) halons destroy the earth's protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun. CFCs and HCFCs also warm the lower atmosphere of the earth, changing global climate. Hydrofluorocarbons (HFCs) also act to warm the planet. The Minnesota Pollution Control Agency (MPCA) is working with industry, residents and government to reduce the damage done to the ozone layer and global climate by CFCs, HCFCs, HFCs and related chemicals.
