The thinning of the ozone layer, called the (7),is worrisome because without ozone all organisms on Earth are subject to harm from toomuch your textbook, read about each statement below, write trueor is another name for a are made up of carbon, fluorine, and CFCs are synthetic usually react readily with other were developed as replacements for toxic GUIDE FOR CONTENT MASTERYCHAPTER1atmosphereoxygen gasozoneozone holestratospheretroposphereultraviolet radiationCopyright Glencoe/McGraw-Hill, a division of the McGraw-Hill Companies.
