    the point at which the earth is farthest from the sun
  2. perihelion
    the point at which the earth is closest to the sun
  3. lines of longitude
    imaginary lines that run north and south across the earth
  4. lines of latitude
    imaginary lines that run east and west across the earth
  5. coriolis effect
    the way in which the rotation of the earth bends the path of winds, sea currents, and objects that fly through different latitudes
  6. air mass
    a large body of air with relatively uniform pressure temperature and humidity
  7. weather front
    a boundary between two air masses
  8. whats the diff between weather and climate
    weather changes from day to day, while climate does not.  **Climate is what you generally expect from a region, while weather is what actually happens from day to day.
  9. what are the 3 main factors that affect the weather
    thermal energy, uneven distribution of thermal  energy, and water vapor in the atomsphere
  10. identify each cloud type
    cumulus, cirrus, stratus, lenticcular

  11. if stratus clouds are dark what are they called
  12. if you find lenticular clouds higher than usual they are called
  13. what does insolation stand for
    incoming solar radiation
  14. in the northern hemisphere is the length of days greater or less than 12 hours between june 21 and September 22? are the days increasing of deacreasing over that time
    more and its deacreasing in length
  15. in the southern hemisphere between what dates are the days lengths less than 12 hours but increasing
    june 21 and september 22
  16. is it summer in the northern hemishper during aphelion or perihelion
  17. what causes wind
    the tremendouds temperature difference between the poles and the equator
  18. why isn't there constant stream of wind blowing from the po,les to the equator
    the corilois effect bends the wind patterns
  19. what causes wind patterns to blend in different regions
    the Coriolis effect bends the wind patterns
  20. suppose you are in Alaska and u want to shoot a missle at the equator due south of your location. in what direction would you aim the missle
    south east
  21. at nighttime high elevations usually cool faster than low elevations. thus at night the land on the mountain is usually cooler than the land in the valley next to the mountain. will the local wind produce by this effect blow from the mountain into the valley or from the vally up the mountian
    from mountain to the valley
  22. is the humidity high or low in a continentional polar air mass. is the mass warm or cold
    low, cold
  23. is the humidity high or low in the maritime tropical air masses . is it cold or warm
  24. over a period of a couple days the clouds slowly build and then a gentle long rain ensues that lasts about 20 hours. what kind of frount causes this
    warm front
  25. over a period of days you notice cirrus clouds forming then stratous and nimbostratous. in just a few hours dark cumulonimbus clouds form heralding a thunder storym . what font caused this
    occuluded front
  26. in less than a dy dar cumulonimbus clouds form and unleash a thunderstorm that lats only a few hours. when the storm is over do you excpect cooler or warmer temperatures as compared to the temperature before the clouds began forming.
