MEA 130 Exam 1 Questions with Correct Answers Latest Update 2025-2026
meteorology - Answers this word is derived from the Greek word "meteoros"
weather - Answers the specific conditions of the atmosphere at a particular place and time
climate - Answers "average weather" or the mean conditions of the atmosphere over an extended
period of time
adage - Answers These specific or mean conditions are defined by six major elements
storm prediction center, national hurricane center - Answers two NWS owned centers for weather
prediction and aid
synoptic - Answers this word os derived from the greek stem syn, which means together
100,000 - Answers how many thunderstorms do we have in the US every year
atmosphere - Answers is a thin gaseous envelope
heat waves - Answers Which meteorological phenomenon, in an average year, is responsible for the
most number of fatalities in the United States?
10,000 - Answers Roughly how many of the 100,000 thunderstorms that the United States experiences
each year will be deemed "severe" by the NWS prompting warnings?
nitrogen and oxygen - Answers these two things make up most of the atmosphere
water vapor - Answers Which constituent of the Earth's atmosphere is most important from a
meteorological perspective?
ozone - Answers Which gas is a photoreceptor of lethal uv solar radiation, preventing it from reaching
the Earth's surface.
30 - Answers Nearly 99% of the mass of Earth's atmosphere lies with ______ km of the surface.
summer - Answers The depth of the troposphere across the Northern Hemisphere is usually greatest
during ___________ .
500 - Answers What would you expect the barometric pressure outside of a jet flying at 5.6 km to be?
troposphere - Answers From the Greek word "Tropein" meaning to turn or change
Troposphere - Answers The air is very well mixed, Molecules can circulate through the entire depth
within a day or so, and Most of what we call "weather" occurs within this region occurs in the
solar radiation - Answers accounts for more than 99.9% of the energy that heats the earth and its
atmosphere
, rotation - Answers earth rotates on its axis once per 24 hours
Revolution - Answers earth moves around the sun in a slightly elliptical orbit once per 365.25 days
Summer Solstice - Answers Astronomical start of summer. june 21st
Tropic of Cancer - Answers 23.5o N,
tropic of cancer - Answers in the tropic of cancer the Sun is at its highest position in the sky, as a result,
radiation shines down on the surface more directly than at any other time of the year. longest "day" of
the year
Winter Solstice - Answers Astronomical start of winter, December 21,
tropic of capricorn - Answers The noon sun is directly overhead at 23.5o S, the
tropic of capricorn - Answers the tropic of capricorn is where the Sun is at its lowest position in the sky,
as a result, radiation shines down on the surface:less directly than at any other time of the year.
Shortest "day" of the year
Autumnal Equinox - Answers Astronomical start of autumn, September 23
Vernal Equinox - Answers Astronomical start of spring, March 20
Heat - Answers energy transferred into or out of an object because of temperature differences
Conduction - Answers Transfer of heat by molecular activity from one substance to another
Convection - Answers vertical transfer of heat
Advection - Answers Horizontal transfer of heat by the mass movement or circulation of a fluid
Radiation - Answers Transfer of heat through the propagation of electromagnetic waves, which only
release heat when they strike an object
Solar Radiation - Answers transfer occurs at the speed of light, transfer does not need a medium
(molecules), therefore it can occur in the vacuum of space
uv-c - Answers most harmful
Laws of Radiation - Answers All objects continually emit radiant energy over a range of l s,
Hotter objects emit more radiant energy than colder objects (per area) as quantified
Stefan - Boltzmann Law - Answers Using the _________, we can calculate the amount of energy emitted
by the sun and the earth
Wien's Displacement Law - Answers Using_______, we can calculate the wavelength at which the sun
and the earth emitted the most radiation:
