  2. Radiation: a. Can be transferred through a vacuum b. Is more like conduction than like convection c. Cannot be thought of as consisting of particles d. Supplies only a minute portion of earth’s energy
  3. The Northern Hemisphere has its maximum tilt toward the Sun on the: a. March equinox b. June solstice c. December solstice d. September equinox
  4. According to Wien’s law: a. The wavelength of peak radiation is proportional to temperature b. The radiation emitted from earth must be 4 micrometers or longer c. Wavelength is proportional to the fourth power of intensity of radiation d. The sun’s energy intensity peaks in the visible portion of the electromagnetic spectrum
  5. Reflection: a. Occurs simultaneously with absorption b. Is called diffuse reflection when done by a mirror c. Is redirected light d. Occurs with only some substances
  6. The single factor that determines how much energy a blackbody radiates is its: a. Mass b. Volume c. Density d. Temperature
  7. The difference between “Rayleigh” scattering and “Mie” scattering is: a. The wavelengths of the incoming radiation b. The size of the scattering particulates c. The angle of the incoming radiation d. The length of time the sun shines e. Only A and B
  8. The subsolar point: a. Is at the Tropic of Caner on the June solstice b. Never moves more than 23.5 degrees in a year c. Reaches above the Arctic Circle only in summer d. Is independent of the solar declination

  1. Most of the radiant energy emitted by Earth is in the form of ____longwave____ radiation
  2. Temperature is the troposphere decreases as you move away from the surface
  3. The ____ionosphere___ is characterized by the large quantity of charged particles it contains.
  4. The earth’s radiation is strongest in this portion of the spectrum, the infrared_
  5. A rising parcel of unsaturated air cools at the DALR
  6. The percentage of visible light reflected from an object is that object’s albedo
