what is meteorology? - correct answer- study of the Earth's
atmosphere
T or F? weather forecasting is a subset of meteorology - correct
answer- True
why is meteorology a non-perfect science? - correct answer- - a
non perfect science because it's always changing
what is weather? - correct answer- the current state of the
atmosphere
what is climate? - correct answer- collective state of the Earth's
atmosphere over a long (30 years) period of time
,2 | Page
what defines an atmosphere? - correct answer- gasses that
surround the Earth and other planets
weather is produced approximately _______ miles up - correct
answer- 4-10
T or F? composition of the atmosphere is constant from place
to place and time to time - correct answer- false. composition is
NOT constant
Aristotle - correct answer- - 340 BC
- father of meteorology
- wrote Meteorologica (a document on weather and how we
observe clouds in the atmosphere)
- Largely incorrect; technology corrected him
- mostly theoretical/basic ideas
- developed the first writings and documents of weather
what does a thermometer measure? who invented the first
thermometer? - correct answer- - measures temperature
- invented by Galileo (1593)
,3 | Page
how does a thermometer work? how is the thermometer
maximum/minimum measured? - correct answer- - expansion
and contraction of liquid on an indexed scale
- maximum measured with mercury
- minimum measured with alcohol
what does a barometer measure? who invented the first
barometer? - correct answer- - measures pressure
- invented by Torricelli (1643)
what does a hygrometer measure? who invented the first
hygrometer? - correct answer- - measures moisture
- invented by Davinci (1660)
why are the 1600's significant? - correct answer- time of many
many advancements in meteorological technology
what does an anemometer measure? who invented the first
anemometer (4 cup anemometer)? - correct answer- -
measures wind speed
- invented by Robinson (1864)
, 4 | Page
when was the telegraph invented and why is it significant to
weather? - correct answer- - invented 1843
- first long distance communication
- Changed the world by giving us the ability to communicate
more; made spreading information about weather to different
areas possible
who developed the air mass frontal theory and when did the
U.S begin to use it? - correct answer- - developed by
Norwegians 1920's
- not used in US until 1940's
what are the 8 elements of weather? - correct answer- 1. air
temperature - hotness or coldness of the air dependent on
motion of molecules
2. humidity - the moisture in the air
3. clouds
4. precipitation- snow, rainfall, what a weather radar detects
5. wind direction
6. wind speed - gusts of air molecules
7. visibility - the ability to see in the sky depending on the
weather
8. air pressure - weight of air
