MEA 130 NCSU EXAM 1 STUDY GUIDE
Earth's axis tilt - Answers :23.5°
Atmosphere - Answers :Thin gaseous envelope, 99% within 30km, protects from uv
Climate - Answers :"Average weather" or mean conditions over extended period of time
Elements of weather and climate - Answers :-temp of air
-humidity of air, moisture
-cloudiness
-precipitation
-pressure
-wind
Environmental lapse rate - Answers :Temperature decrease in the troposphere (6.5°C
per kilometer)
Meteorology - Answers :Derived from Greek "meteoros" or anything that falls from their
sky
Weather - Answers :Specific conditions of the atmosphere at a specific place and time
Hydrosphere - Answers :All water on the planet, 97% or earth's water covers 71% or
surface
Ozone O3 - Answers :40ppb, photoreceptor of dangerous uv
H2O - Answers :0 to 4% most meteorologically important gas, greenhouse gas
CO2 - Answers :390ppm, absorbes long wave radiation from the earth, greenhouse gas
Argon - Answers :~1%
Nitrogen - Answers :78% of atmosphere
Troposphere - Answers :Greek "Tropein" turn or change, air is mixed well, most weather
occurs here
Radiosonde - Answers :Sent up in atmosphere to collect data
Stratosphere - Answers :Stratified, not well mixed, temp inversion increase with height
Tropopause - Answers :Isothermal layer, Around 12km "Equal tempature" separates
troposphere from stratosphere
