Meteorology
Why does the sky look blue
As light moves through r the atmosphere, most of the longer wavelengths pass through. Little of red, orange, and yellow is affected. Blue scatters first
Exosphere
Atmosphere is very thin, region where atoms and molecules escape into space
Instrument that measures atmospheric pressure
Barometer
Explain the green house effect
Green house gases ( water vapor, carbon dioxide, and methane) create a spherical green house around earth allowing sunlight to come in, but more difficult to come out
What is the ozone layer made of
O3
What unit is used to measure air pressure
PSI
Define conduction
Process by which heat or electricity is directly transmitted through a substance when there is a difference of tempature or of electrical potential, without movement f material
Definition of Meteorology
Science that deals with the phenomena of the atmosphere, especially weather and weather conditions
What does the ozone layer do
Sheila that protects earth from the Suns ultraviolet (UV) Rays
Examples of low albedo
Soil, sand
Definition of weather
State of the atmosphere at a given time or place
Where is the ozone layer
Stratosphere
Define convection
Tendency of hot liquid ( less dense) to rise while colder liquid( more dense) to sink
Where does wether take place
Troposphere ( first layer)
Thermosphere
UV radiation causes photoionization/photodissociation of molecules. Where aroraborialys
How does a Mercury barometerwork
Upsilon glass tube standing in an open bath of mercury. Air pressure pushes down on the surface making more rise higher in the tube
What Is air pressure
Weight of the atmosphere pressing down on earth
Stratosphere
2nd major atmospheric layer above troposphere, no weather, 15% of total mass of atmosphere
Mesosphere
30-50 miles high . Shooting stars(meteors), gases start to break down metors
Gases in atmosphere
78% nitrogen, 21% oxygen
Examples of high albedo
Coulds, ice, snow
Define radiation
Emission of energy as electromagnetic waves or as moving subatomic particles, especially high energy particles
Albedo of 100%
Everything reflect of
Troposphere
First layer, the layer we are in, site of all weather
Albedo
Fraction of solar energy reflected from earth back to space
