Flashcards in Human Impact Deck (47)
The oxygen we breath contains ______ ______ ____ bonded together
2 oxygen atoms
ozone molecule consists of
1 oxygen atom
ozone is ________ if we breath it
what does ozone do in the stratosphere and why is it important to us
protects life by absorbing harmful UV rays from the sun
stratospheric ozone is destroyed by man made and natural
describe why lack of ozone is bad for life on earth
will give us UV rays, cancer, and global warming
we live in the
list of layers of atmosphere, ground-up
troposphere, stratosphere, mesosphere, thermosphere, exosphere
How does temperature change in each layer
as altitude increases?
decrease in temperature = density of the air molecules
Oxygen molocule we breathe
Oxygen molocule in ozone
are regions in the stratosphere
where little ozone remains
ozone holes develop annually in the _____ regions
____ ______ concentrate the ozone-destroying
chemicals in the polar region.
accelerate the reactions that destroy
years where the polar ozone holes have grown larger
years where the polar ozone holes have begun to repair
with warmer winter temperatures and reduced
inject volcanic gases high
into the atmosphere.
explosive volcanic erruptions
One of these volcanic gases,____ _____, has an effect on
sulfur dioxide's _______ reflect some _____ _______ back into
space, causing the Earth’s surface to ____ — an effect
that typically lasts for _____.
aerosols, solar radiation, cool, years
also hasten the depletion of the ozone
What happens to heat from the sun
Heat hits the ground and some bounces back
What do Greenhouse gases do?
They trap the heat that is bouncing back
What would happen if we didn’t have GHG?
The Earth’s average temperature would be below
What happens if we have too much of the gasses?
The Earth’s temperature skyrockets!!
With just the right amount of gasses, the planet is ____ enough to
support life over most of its surface.
What are the Greenhouse gases?
water vapor , carbon dioxide,
ozone, methane, and nitrous oxide.
(most important) ghs
earths atmosphere is
0.04% carbon dioxide
