Layers of the Atmosphere
atmosphere
the blanket of gases that surrounds the earth
tropopause, stratopause, and mesopause
what are the boundaries in the layers in the atmosphere in order
troposphere, stratosphere, mesosphere, and thermosphere
what are the layers of atmosphere in order?
cancer, genetic mutations, and sunburn
what can suns ultraviolet light cause
there isnt an ozone layer
what causes the temperature to decrease with height through the mesosphere
the ozone layer absorbs ultraviolet radiation
what causes the temperature to increase with height through the stratosphere
suns ultraviolet radiation
what does ozone protect us from
85-90 km
what is the height for the mesopause
46-54 km
what is the height for the stratopause
12-18 km
what is the height for the tropopause
-90
what is the temperature for the mesopause
-2 to 0
what is the temperature for the stratopause
-60
what is the temperature for the tropopause
78%
what percentage of nitrogen is in the atmosphere
1%
what percentage of other gases, argon, carbon dioxide, and water vapor is in the atmosphere?
21%
what percentage of oxygen is in the atmosphere?
nitric oxide and chlorofluorocarbons
which two atoms and molecules can cause the depletion of ozone
the air is thinner but contains the ozone layer and the temperature increases
describe temperature changes in the stratosphere.
troposphere
determine which layer of the atmosphere has the greatest temperature range
decrease
does the mesospheres temperature increase or decrease with altitude
clouds will block the earths surface which will cause less radiation to get through
explain how cloud cover can influence temperature in the lower atmosphere
troposphere
WHICH LAYER IS: -closest to earth -contains most mass -weather takes place here
mesosphere
WHICH LAYER IS: -due to lack of ozone, the temperature generally decreases with increasing altitude
ozone
WHICH LAYER IS: -formed by addition of third oxygen atom to molecule -protects us from UV rays
stratosphere
WHICH LAYER IS: -made of ozone -due to absorption of radiation temperature, the layers temperature increases
thermosphere
WHICH LAYER IS: -small amount of atmosphere mass -good amount of volume -temperature can reach 1000 degrees
increase
does the stratospheres temperature increase or decrease with altitude
increase
does the thermospheres temperature increase or decrease with altitude
decrease
does the tropospheres temperature increase or decrease with altitude
solar energy
earths surface is the primary absorber of what type of energy
