EAS-131 TESU TECEP Exam; Questions and
Answers 100% Correct
What is the definition of meteorology? Correct answer-The study of the atmosphere and
the associated weather phenomena
What are the functions and applications of meteorology? Correct answer-1) Weather
observation and forecasting
2) Computer modeling of the atmosphere
3) analyzing, monitoring, and predicting air pollution
4) Earth science education
5) Helping industries (agriculture, energy, aviation, insurance, etc.) manage the risks posed by
weather
6) Assisting emergency managers and disaster planners
7) Studying Earth's climate and climate change
What is the composition of the atmosphere (Permanent Gases)? Correct answer-1)
Nitrogen (N2)- 78.08%
2) Oxygen (O2)- 20.95%
3) Argon (Ar)- .93%
4) Neon (Ne)- .0018%
Define radiation Correct answer-the emission and transmission of energy through
particles or waves
, EAS-131 TESU TECEP Exam; Questions and
Answers 100% Correct
Define electromagnetic spectrum Correct answer-the range of wavelengths or
frequencies over which electromagnetic radiation extends.
Define conduction Correct answer-The transfer kinetic of energy from particle to particle.
Give and example of conduction Correct answer-Cold spoon into hot soup
Define thermal conductivity Correct answer-The ability of an object to transfer heat
Why is the air closest to the surface warmer during the day? Correct answer-conduction
from the earth's surface to the air in contact with it
Why is the air closest to the surface cooler at night? Correct answer-earth's surface has a
radiation deficit, thus cooling and conduction then cools the air in contact with the surface
What is a nocturnal inversion? Correct answer-When low level air temperatures are
cooler due to conduction, while temperature of the air above increases with altitude
Define convection Correct answer-The transfer of heat via vertical movement of air
, EAS-131 TESU TECEP Exam; Questions and
Answers 100% Correct
What is free convection? Correct answer-Warm air rising freely
Define Planck's law Correct answer-Every object emits radiation at all times and at all
wavelengths.
Define Wien's Law Correct answer-The hotter an object, the shorter the wavelength at
maximum emission. (The hotter the object the brighter)
According to Wein's law where does peak emission occur? Correct answer-At infrared
wavelengths
Stephan-Boltzmann Law Correct answer-As temperature increases so does the amount of
energy emitted
Kirchhoff's Law Correct answer-With constant temperature, an object that absorbs
radiation efficiently at a particular wavelength will also emit radiation efficiently at that
wavelength.
When electromagnetic radiation strikes a surface what can happen to the radiation?
Correct answer-1) Absorption
2) Scattering
3) Transmission
, EAS-131 TESU TECEP Exam; Questions and
Answers 100% Correct
Define radiation transmission Correct answer-When radiation passes through an object
virtually unaffected
What is an example of radiation transmission Correct answer-Visible light passing
through a glass window
Describe radiation absorption Correct answer-Extinguishing of radiation, amount of
radiation extinguished depends on radiation wavelength and object composition
Describe radiation scattering Correct answer-Reflecting of radiation off an object
What is forward scattering? Correct answer-When radiation scatters in a forward
direction
What is back-scattering? Correct answer-When radiation returns in the direction it came
from
What is albedo? Correct answer-The portion of solar radiation that is scattered
