|
The Atmosphere is Seperated INto How Many Main Layers? Name Them
|
4 Troposphere Stratosphere Mesosphere Thermosphere
|
|
|
What Is The Troposphere?
|
Lowest Layer. 75% of Air. All Weather. Higher the Colder. Top=JetStreams (Fast Air Affects Weather)
|
|
|
What Is The Stratosphere?
|
Horizonatal Flow. Ozone Layer. Higher the hotter.
|
|
|
What is The Mesosphere?
|
Higher The Colder (Coldest Layer)
|
|
|
Thermosphere
|
Contains Ionosphere (reflects radio waves)
|
|
|
Exosphere?
|
Auroras Found Here Last layer
|
|
|
Air Pressure
|
Force That Air Pushed On things
|
|
|
Why does Air Exert Pressure?
|
Because It Has Gravity
|
|
|
How Much Does Air Way?
|
14.7 Pounds Per Square Inch At Sea Level
|
|
|
In What Direction Does Air Exert Pressure?
|
All Directions
|
|
|
What Factors affect Air Pressure?
|
Altitude-Higher you Go Lower The Air Pressure. Less ON Top Of You
Teperature-Higher The temp. Lower Air Pressure (Molcules Spread Apart) Humidity-Higher Humidty Lower Air Pressure (water Vapor Weights Less Than Oxygen and Nitrogen) |
|
|
Air Pressure At Sea Level Can Supprt -- Inches Of Mercuray
|
30
|
|
|
Air Presuusre Is Measured By
|
Instruments called Barometers
Mercury-Actual Mercury Aneroid-Collapsed Can w. No Air |
|
|
How does the sun produce energy?
|
Nuclear Fission
|
|
|
How Much of The Suns Energy Does Earth Recieve?
|
A Tiny Fraction
|
|
|
The Earth is _________ Distance from Earth/Average temp That is maintained is.
|
perfect/ 15 C
|
|
|
Water Cycle
|
allows water to exsit in all three forms and provides fresh water to land.
|
|
|
Radiative Balance
|
Whatever energy the earth recieves is sent back to space
Some earth surfaces absord life/rest is sent back too space as light/or emitted back as heat |
|
|
Water Vapor and Carbon Dioxide
|
trap and Hold heat before emmitting it to space. Green House Effect. Helps Keep Earth Warm Esp. At Night
|
|
|
Earth is Heated Unevenly Because
|
Of Its spherical Shape.
tries to balance out |
|
|
Equater
Poles |
Equator-Recieves More Direct and Concentrated heat =Hot
Poles=Receves less direct and concetrated heat=cold |
|
|
Equter Hot=Air Pressure=
Poles=cold=Air Pressure= |
LOW Air Rises
HIGH Air Sinks |
|
|
The Uneven Heating Causes
|
Convection Current= Earths Major Wind Systems
|
|
|
What way does winds on earths surface blow?
|
high pressure to low
|
|
|
Coriolis effect
|
winds that are effected by earths' rotation causing the winds to be deflected from there origional path
|
|
|
Winds Blow
|
the the right in the northern hemisphere
to the left in the southern hemisphere |
|
|
Name Pressure Zones
|
Equater (0*Laditude) Low Rises
30* Laditude=High Sinks 60* Ladidtude= Low Rises 90* Laditude= High Low |
|
|
Waht Creates Earths Major Wind Systems
|
Coriolis Effect. Unequal heating
|
|
|
trade Winds
|
strongest steadiest winds on earth. blow from 30* to equater
|
|
|
