Geosphere, atmosphere, hydrosphere, biosphere
Consisting of solid earth (no living things). Extends from earth's surface to its core (4,000 miles)
Protects earth from radiation. 99% of it is within
18-20 miles of earth's surface. Weather occurs here
Oceans, lakes, rivers, streams, glaciers, underground water. Oceans make up 71% of the earth's surface
Includes all life on earth
A group of interacting or interconnecting parts that form a complex whole
More complicated; allows for transfer of matter (water cycle)
Self contained system; no transfer of matter (sphere on desk)
Positive feedback mechanism
Mechanism that enhances or drives change (evolution, climate change)
Negative feedback mechanism
Mechanism that maintains the system's status quo (sweating)
Major components of the atmosphere
Hydrogen (78%) and Oxygen (21%)
UN treaty in 1987, ratified by 190 nations, created legal controls on production and consumption of ozone depleting chemicals
Troposphere, stratosphere, mesosphere, thremosphere
Temperature decreases with altitude.
Temperature levels off at an altitude between 5-7 miles.
Temperature decreases in the troposphere called the environmental lapse rate.
Temperature increases with altitude until reaching the stratopause (30 miles).
The ozone layer is concentrated in the stratosphere.
Temperature decreases with altitude until reaching the mesopause (50 miles).
The coldest temperatures in the atmosphere occur in the mesopause .
The thermosphere has no well defined upper limit.
Temperature increases to 1800℉.
Environmental lapse rate
3.6℉ per 1000 ft
Occurs when earth's magnetic field traps solar particles
Occurs in the Northern hemosphere
Occurs in the Southern hemoshpere
