QUESTIONS WITH FULL SOLUTION
●● scientific method
Answer: 1. posing a question
2. hypothesis
3. what if hypothesis is true?
4. test
●● weather
Answer: -air temperature
-air pressure
-humidity
-clouds
-precipitation
●● geostationary satellites
Answer: orbit at the same speed as Earth's rotation and continuously
observes what is happening on surface, 22,300 miles above earth
●● middle latitude cyclone storm system
Answer: -outside tropics and northern hemisphere
,-low pressure systems (warm and cold fronts)
-air is moving counter clockwise and air in middle is pushed up
●● weather map elements
Answer: -wind: horizontal movement of air
-wind direction:wind is blowing FROM
-fronts: boundaries that separate warm and cool air, sharp change in
temp.
●● early atmosphere
Answer: -early atmosphere was mostly hydrogen and helium
-CO2 and H20 escaping from Earth's cooling core caused rain
-lakes and oceans absorbed CO2 from atmosphere
-plants evolved and produced oxygen for current atmosphere
●● composition of todays atmosphere
Answer: -20 miles of earth's surface
-no definite upper limit
-78% Nitrogen and 21% oxygen, argon, neon, helium, xenon, water
vapor, and CO2
●● ozone
Answer: -filters our harmful sun rays
, -good up high, and bad up close (ozone is an air pollutant)
●● density
Answer: number of molecules in a given space, lower as you go up
●● air pressure
Answer: force exerted over an area of surface; less w height
●● standard sea level pressure
Answer: 1013.25 mb or 29.92 Hg
●● lapse rate
Answer: rate that temperature decreases with height
●● temperature inversion
Answer: increases by height
●● atmosphere layers
Answer: 1. troposphere (where we live)
2. stratosphere
3. mesosphere
4.thermosphere
