Variable Gas
proportions do change over time/space
How much does water vapor make up variable gas
0-4%
Ozone layer
absorbs uv rays and has decreasing crc’s
Carbon dioxide is increasing due to what
burning of fossil fuels and deforestation
Particulates
solid particles that are microscopic in size and are suspended in the air
4 major particles
dust, smoke, salt, protein
Atmospheric Pressure
force applied to the earth’s surface by the weight of the overlying atmosphere
When is atmospheric pressure the highest?
sea level
How does atmospheric pressure decrease?
Decreases upward at a decreasing rate
Temperature inversion
increase of temperature with height in the atmosphere
When does temperature inversion decrease?
decreases with height close to surface
What is in the troposphere
clouds and weather
What decreases in the troposphere with height
temperature
Tropopause
transistion zone; no change in temperature
What kind of temperature is in the stratosphere
temperature inversion
What happens to the temperature in the mesosphere
decrease of temperature with height
What kind of temperature is in the thermosphere
temperature inversion
