earth science the 4 layers of the Atmosphere Flashcards
the layer where most weather occurs
Troposphere
the layer which supports life
Troposphere
0-10km from the earth surface
Troposphere
average temp= 15C (at surface)_ -6C (decreased)
Troposphere
80% of atmospheric gases by mass
Troposphere
most CO2, water vapor and atmospheric dust
Troposphere
Above troposphere
Stratosphere
10km-50km above surface
Stratosphere
temp increase away from the surface -60C_0C
Stratosphere
contains most ozone (03(g)) making the ozone layer
Stratosphere
ozone captures energy from the sun, increasing temp with altitude
Stratosphere
third layer
Mesosphere
temp range: 0C_-100C
Mesosphere
very little gas
Mesosphere
50km-80km
Mesosphere
farthest layer
Thermosphere
temp range: -100C_1500C (increases) due to higher concentration of solar radiation
Thermosphere
80km-700km and very little gas
Thermosphere
A thin layer of earth with conditions suitable for supporting life
Biosphere
composed of all living things on earth and physical environment supporting them
Biosphere
a solid portion of earth floating above semi-fluid and upper mantle
Lithosphere/Geosphere
Extends from earth surface to 100km below
runs under continents and oceans
Lithosphere/Geosphere
Warmed mainly by the sun and a little bit by the molten mantle
Lithosphere/Geosphere
differences in the Lithosphere (ex. amount of albedo) can affect of atmospheric water vapor, as well as our environmental conditions.
Lithosphere/Geosphere
portion life exists on is the crust
Lithosphere/Geosphere
the crust is the part of the lithosphere that life exists on and is eggshell thin
Lithosphere/Geosphere
WATER
Hydrosphere
97% is salt water in oceans
Hydrosphere
3% is freshwater. lakes or streams (most freshwater is snow and glaciers or groundwater)
Hydrosphere
amount of water stays the same
Hydrosphere
warmed mainly by the sun
Hydrosphere
it is the sum of frozen water around the global
Cryosphere
By volume, the perennial ice- containing cold regions of the world are dominated by the continental ice sheets of Greenland and Antarctica
Cryosphere
Sea ice and snow, have much less volume but are large in areal extent. Ice sheets, snow, and sea ice play a critical role in the Earth’s climate.
