Explain how a small amount of chlorofluorocarbons can destroy a large amount of ozone.

Chlorofluorocarbons are more commonly known as CFCs. CFCs were once used as refrigerants, propellants (in aerosol applications), and solvents. Once CFCs enter the atmosphere, they slowly rise to the stratosphere. Here, ultraviolet radiation causes the break up of CFCs into their individual chlorine atoms. The chlorine atoms cause the catalytic destruction of ozone. 

This is s cute awee : (( . well if she's showing you signs that she may like you , then shoot your shot ! don't be afraid . & if you're unsure that she's giving you these signs , then wait out for a little bit . most girls are different . some may act really sweet , but only bc you're a good friend of hers . that , or she might like you . you just never know . but i think you should sit down with her & tell her how you feel . but don't be awkward & shy . just be straight up & tell her how you feel . if the feelings aren't mutual , then don't cry about it . you need to respect her decision & look for others in the world . feelings can be difficult & confusing , but don't be afraid to show them . i say you play it out & if you're still unsure about it , talk to her . - rach
