Geography 1900 Exam 2 with ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




accurate detailed solutions ||//\\|| ||//\\||




atmospheric pressure - correct answer✔✔weight of the column of air above given unit ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




area of the Earth's surface
||//\\|| ||//\\|| ||//\\|| ||//\\||




relationship to atmospheric pressure and altitude - correct answer✔✔as altitude ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




increases, AP decreases ||//\\|| ||//\\||




as altitude decreases, AP increases
||//\\|| ||//\\|| ||//\\|| ||//\\||




measuring atmospheric pressure (2) - correct answer✔✔1) mercury barometer: as AP ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




increases, mercury goes up the tube ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




2) aneroid barometer: as AP changes, the point points to the AP
||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




equation of state - correct answer✔✔relationship between pressure, density, and
||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




temperature
pressure = (density)(R)(temperature) ||//\\|| ||//\\||




relationship between density and temperature - correct answer✔✔as temperature ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




increases, density decreases ||//\\|| ||//\\||




as temperature decreases, density increases
||//\\|| ||//\\|| ||//\\|| ||//\\||




spatial pressure gradiant - correct answer✔✔change in pressure in space
||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




pressure gradient force (PGF) - correct answer✔✔force associated with pressure
||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




gradients // generates wind by pushing HP to LP ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




hydrostatic equilibrium - correct answer✔✔VPG = (-density)(gravity) ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||

, the forces offset each other and creates equilibrium
||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




relationship between temperature and VPG - correct answer✔✔as temperature ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




increases, density decrease, so VPG decrease ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




as temperature decreases, density increases, so VPG increaes
||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




for warmer column to reach the same pressure level as colder air... - correct
||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




answer✔✔one must move further up in the warmer column because increased altitude ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




leads to colder air ||//\\|| ||//\\|| ||//\\||




winds - correct answer✔✔horizontal movement generated from PGF (where HP pushed
||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




to LP)
||//\\||




relationship between vertical winds and horizontal winds - correct answer✔✔verticals ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




winds are much weaker than horizontal winds ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




two important influences of winds when wind begins to move - correct answer✔✔(1)
||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




friction
(2) coriolis effect ||//\\|| ||//\\||




coriolis effect - correct answer✔✔-effect of rotation on movement observed ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




-magnitude = speed of movement ||//\\|| ||//\\|| ||//\\|| ||//\\||




-NH=right // SH=left ||//\\|| ||//\\||




-0 at the equator and increases with latitude (max at the poles)
||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




what does coriolis effect not influence - correct answer✔✔-does not influence sinks and
||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




toilet drains because they only last a few seconds ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||




-coriolis effect is applied to rotation of long hours and long kilometers ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\|| ||//\\||
