Earth_Sciende

Earth Sciende Atmosphere Gas – Nitrogen (most abundant), oxygen, / carbon dioxide – has the ability to absorb heat radiated by earth, water vapor Atmosphere Pressure is in MB – Atmosphere pressure in the PPI – Atmosphere pressure at sea level – slightly more 1000 millibars, pressure decrease with altitude 3.5 miles 50% atmosphere is below 10 miles 90% atmosphere is below Atmospheric carbon dioxide is transparent to incoming Short-Wavelength solar radiation. But it is not transparent to some of the Long –Wavelength outgoing terrestrial radiation. Ozone –combines 3 atom oxygen (03) / concentrate between 10-50 kilometers above the stratosphere / absorbs harmful ultraviolet radiation Thermosphere – upper limit - Mesosphere – temperature decreases - Stratosphere – above the troposphere – temperature increases at top Troposphere – lowermost layer - all important weather phenomena occur - temperature decreases with altitude *** - There is pause in between each Equinoxes – occur midway between the solstice - length day equal night - Sept 22-23 march 21-22(spring) Sun angles – near water climate = cool summer, warmer winter Northern hemisphere – June 21-22 (summer) – December 21-22 (winter) Heat transferred in our Earth System -Conduction – transfer of heat through matter by molecular activity Convection – pressure, air, water, high, temperature, heat, between, wind, warm, vapor, transfer, hemisphere, change, atmosphere, winds, weather, transparent, system, summer, subtropical, sea, radiation, produce, oxygen, occur, miles, mass, low, level, layer, humidity, gas, equal, earth, dioxide, decreases, cold, carbon, actual, abundant, above, atmosphere, –wavelength, combines, zone, wispy
