-Thin layer of earth -Can sustain human life -Made up of 3 abiotic components |
Biosphere |
|
|
-Solid part of Biosphere -Composed of rocks, minerals and elements -Consists of upper crust and mantle -Varies in thickness |
Lithosphere |
|
|
-Liquid part of Biosphere -Composed of all liquid on earth -97% salt, 3% fresh |
Hydrosphere |
|
|
-Gaseous part of Biosphere -Rises 500km from earth's surface -Composed of gases |
Atmosphere |
|
|
The percent of solar radiation that a surface reflects at any particular time |
Albedo (Ice berg has bigger albedo than a field) |
|
|
What happens when particles absorb energy? |
Energy gets converted into another form of energy |
|
|
-Composed of all frozen water on earth |
Cryosphere |
|
|
-First layer of Atmosphere -Earth's surface (0-10km) -80% of the atmospheric gases by mass -Only layer to support human life -Contains 99 % of the water vapour and most of the carbon dioxide -Weather occurs here |
The Troposphere |
|
|
-Second layer of Atmosphere -Earth's surface (10-50km) -No weather occurs here -contains 90% of the ozone gas in the atmosphere -Absorbs sun's rays -Temp increases with altitude -Absorbs UV rays -Cancer |
The Stratosphere |
|
|
-Third layer of Atmosphere -Earth's surface (50-90km) -Decreasing temperatures (-110) -Ozone and water vapour are negligible |
The Mesosphere |
|
|
-Fourth layer of Atmosphere -Earth's surface (90-500+km) -Temperature is the measure of the average KE of the molecules -Density of the air is very low -Heat absorbed is low -Result = high temperature but feels cold |
The Thermosphere |
|
|
-Part of Atmosphere -78.08% of Atmosphere by volume |
Nitrogen |
|
|
-Part of Atmosphere -20.95% of Atmosphere by volume |
Oxygen |
|
|
-Part of Atmosphere -0.97% of Atmosphere by volume |
Other Gases |
