Sol quiz #8 Flashcards
Earth and space systems (27 cards)
The suns radiant energy is made up of 3 different types of electromagnetic radiation?
Infrared radiation, visible light and ultraviolet radiation.
Earths energy budget
Describes what happens to incoming solar energy
What happens to that solar energy.
1/3 gets reflected back into space. 1/2 is absorbed by the earths surface, the rest is absorbed by the atmosphere and clouds.
The green house effect
Is what makes the earths temperature suitable for life.
Climate
refers to the long term weather pattern.
Why are extremes in temperature minimized near large bodies of water.
Waters absorbs more thermal energy then land. It intakes more thermal energy during the summer and slowly regales it back during the winter.
Convection current
Rising of warm air and falling of cool air.
How do clouds form.
Water vapor condense and changes into time droplets that collect on dust floating around that makes a cloud.
How do thunderstorms form?
When warm air goes above cool air makes clouds which plays a key role in a thunderstorm.
Air is made of?
78% nitrogen 21% oxygen and 1% of other gases.
Humidity
Amount of water vapor in the air
Relative humidity
Measure of the amount of water vapor in the air at a specific temperature.
Air pressure and altitude
Air pressure decreases as altitude increases
Earths atmosphere
Made of layers of air that surrounds the planet. Earths gravity holds the atmosphere in place .
Thermospher
-outermost layer
-aurora borreallis
Mesosphere
-second outer most layer
- coldest layer of the atmosphere.
Stratosphere
Second layer
-jet planes fly here
- ozone layer protects life on earth from ultraviolet radiation from the sun.
Troposphere
-first layer of the atmosphere
-life exists here
-weather takes place here
air temperature
-thermometer
-location on earth and amount of radiation from the sun affects
air or atmospheric pressure.
-weight of air pressing down on earths surface.
-barometer
-altitude
-density
-temperature
moisture
water in the atmosphere
-hygrometer: both H and RH
-psychometer: measures relative humidity
air mass
A large volume of air that has a similar temperature, pressure and humidity.
fronts
boundaries that separate warm, moist air masses from colder, drier airmasses.
warm front
boundary formed when warm air is replacing cold air.
