|
Visible Light
|
colors. red,orange= longest wave length. blue, purple=shortest wavelength
|
|
|
Infrared Radiation
|
Wavelengths longer than red. Heat, can't see
|
|
|
Ultraviolet Radiation
|
Wavelengths shorter than violet. Invisible. Can cause sunburns.
|
|
|
Most of the energy from the sun trabels to Earth in the form of ____ and ______
|
Visible light. Infrared radiation.
|
|
|
Sunlight is ___,___,_____
|
Most is absorbed (heat land and water), reflected back into atmopsphere, absorbed and radiated back
|
|
|
Greenhouse Effect
|
When atmosphere abosrobs gasses (water vapor, carbon dioxide, methane) to keep the Earth's temperature warm
|
|
|
Temperature Conversion
|
C=5/9(F-32)
|
|
|
Temperature
|
average amount of energy of motion in partciles
|
|
|
Thermal Energy
|
Total energy of motion in particles
|
|
|
Anemometer

|
|
|
Barometer
|
Air Pressure
|
|
|
Hygrometer
|
Humidity

Temperature
|
|
|
Rain Gauge
|
Percipitation
|
|
|
Conduction
|
Direct heat transfer
|
|
|
Convection
|
Heat transfer of liquids. HOt air rises, cool air sinks
|
|
|
Radiation
|
Heat transfer directly from the sun as radiation
|
|
|
Convection, Radiation, and Conduction heat the troposhpere by_________
|
Condcution- from ground up
Convection- the air hot air rise, cool air sink (Major way) Radiation- radiates from sun |
|
|
Hawk can fly up without flapping wings because____
|
Convection. THe warm air rises so hawk goes with warm air and soars up
|
|
|
Sunsets are red because_______
|
by the time it reaches eye only long wave legnths(red etc) remain, shorter wavelenghts scatter.
|
|
|
Radiation wavelegnths- shortest to longest
|
UVI
|
|
|
Same temerature, different amount =
|
same thermal energy
(Namiko is as hot as Peter) |
|
|
Wind
|
horizontal movement of air. form high pressure to low pressure
|
|
|
Winds are caused by____
|
differences in air pressure
|
|
|
Air temperature realted to Air pressure realted to wind
|
differences in air temperature=differences in air pressure= wind
|
|
|
Wind-Chill Factor
|
Wind= remove body heat even if it's warm
|
|
|
Local Winds
|
Wind that blows over short distances
|
|
|
Local winds are caused by___
|
unequal heating of surface within small area
|
|
|
Sea Breeze
|
During day. cool air from sea go to land. warm air rises
|
|
|
Land Breeze
|
During night. cool air from land goes to warm air at sea.
|
|
|
Three Major Global Wind Belts
|
trade winds, polar easterlies, prevaling westerlies
|
|
|
Trade Winds
|
blows from horse latitudes toward equator. east to west
|
|
|
Prevailing Westerlies
|
blow from the horse latitdues to poles. west to east
|
|
|
Polar Easterlies
|
blow cold air away from poles.
|
|
|
Coriolis Effect
|
Earth spins= winds turn
|
|
|
Relative Humidity
|
percentage of water vapor that is in air compared to max amount of water vapor
|
|
|
Humidity
|
amount of water vapor in air
|
|
|
Cirrus Clouds
|
form at high levels. made of ice crystals.wispy,feathery
|
|
|
Cumulus Clouds
|
common on sunny days. fluffy.
|
|
|
Stratus clouds
|
cover all.most of sky. dull, gray. indicate rain,snow,drizzle.
|
|
|
Cloud formation requires____
|
condensation
|
|
|
Process involved for clouds to form _____ and _______
|
presence of particles in the air, cooling of the air
|
|
|
Dew Point
|
temperature where condensation begins
|
|
|
Rain
|
at least 0.5 mm diameter. smaller= drizzle. even smaller= mist

as they fall, they freeze. smaller than 5mm in diameter
|
|
|
Freezing Rain
|
Freezes when touches cold surface.
|
|
|

|
water capor in cloud conervted to icecrystals--> snowfalkes. 6 sides
|
|
|
Hail
|
larger than 5mm in diameter. inside cumulonimbus starts as ice pellet, strong updraft carry through cold region many times becoming bigger
|
|
|
Rain Gauge measures percipitation ______
|
rian enters funnel. amount of rainfall is measured by dipping ruler in water or reading marked scale
