ozone layer
thin part of the earths atmosphere that absorbs the harmful rays from the sun
ozone depletion
breaking down our ozone layer through air pollution
UV Index
a number scale 1-11 that tells you how intense the UV rays are predicted to be
how are the ozone layer and UV Index related
the thinner the ozone layer the higher the UV index
heat index
what the temp feels like to the human body compared to the humidity + air temp.
how are air pollution and heat index related
higher temps with trap air pollutants near the ground
greenhouse effect
process that occurs when gases in the earth’s atmosphere trap the suns heat
human impact on greenhouse effect
humans putting extra greenhouse gasses into the atmosphere causing the average temp to rise.
