UMIAMI GSC 103 EXAM 3 WITH COMPLETE SOLUTIONS
NEW UPDATE!!
Photosynthesizers - ANSWER Earth didn't have oxygen until these came about
Composition of dry air today - ANSWER Mostly nitrogen and oxygen. Little carbon
dioxide and other gases
Troposphere - ANSWER gets colder as you go up
Stratosphere - ANSWER gets warmer as you go up
Mesosphere - ANSWER gets colder as you go up
Thermosphere - ANSWER gets warmer as you go up, BUT less density so it feels
freezing
lapse rate - ANSWER the rate at which temperature falls with increased altitude
Ozone (O3) - ANSWER stuff found in the ozone layer
formed by single atoms of oxygen bumping into O2
absorbs UV light and converts into heat
Relative humidity and temperature - ANSWER As temperature decreases, relative
humidity increases
, low pressure zone - ANSWER A region where relatively warm, lower density air is rising.
high pressure zone - ANSWER A region where relatively cool, dense air is sinking.
The Intertropical Convergence Zone - ANSWER a belt of low pressure which circles the
Earth in the tropical latitudes
Polar Cell - ANSWER Cells of air circulation occurring between 60 degrees north and
south and each pole.
Descending cold, dry air
Ferrel Cell - ANSWER Cell that moves air form 30 degrees to 60 degrees latitude
Rising moist Air
Hadley Cell - ANSWER a large-scale atmospheric convection cell in which warm moist
air rises at the equator and sinks cool dry air at medium latitudes, typically about 30°
north or south.
Coriolis effect - ANSWER Causes moving air and water to turn left in the southern
hemisphere and turn right in the northern hemisphere due to Earth's hemisphere.
downdraft - ANSWER cool air with rain descending out of storm
updraft - ANSWER warm moist air rising into storm
runoff - ANSWER water running across land
downcutting - ANSWER the process in which water flowing through a channel cuts into
the substrate and deepens the channel relative to its surroundings
