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
