CORRECT Answers
1. 23d 26' 22" (23.4394 degrees) north Tropic of Cancer
of the Equator and marks the most
northerly latitude at which the sun
can appear directly overhead at
noon. This event occurs at the June
solstice, when the northern hemi-
sphere is tilted towards the sun to
its maximum extent.
2. Equator an imaginary line drawn around the earth equally dis-
tant from both poles, dividing the earth into northern
and southern hemispheres and constituting the parallel
of latitude 0°.
3. lies at 23d 26' 22" (23.4394 degrees) Tropic of Capricorn
south of the Equator and marks the
most southerly latitude at which
the sun can appear directly over-
head at noon. This event occurs at
the December solstice, when the
southern hemisphere is tilted to-
wards the sun to its maximum ex-
tent.
4. Prime Meridian imaginary line that divides Earth into two equal parts:
the Eastern Hemisphere and the Western Hemisphere.
The prime meridian is also used as the basis for the
world's time zones
5. International Date Line The international date line, established in 1884, passes
through the mid-Pacific Ocean and roughly follows a
180 degrees longitude north-south line on the Earth.

It is located halfway around the world from the prime
meridian — the 0 degrees longitude line in Greenwich,
England.
6. Summer solstice and where the sun June 20th, Tropic of Cancer
is
7. Winter Solstice and where the sun December 21-22, Tropic of Capricorn
is
8. Vernal Equinox March 20th, sun is at the equator
9. Autumnal Equinox September 22nd, sun is at the equator
10. Stefan-Boltzmann law The constant is based on Stefan-Boltzmann's law, which
states that the radiant heat energy emitted from a unit
area of the black body in one second (E) is directly
proportional to the fourth power of its absolute temper-
ature, or E = σ x T4
11. Wien's Law Wien's Law tells us that objects of different temperature
emit spectra that peak at different wavelengths.
12. Properties of Longwave radiation infrared light, less energy remitted by the earth
13. Shortwave Radiation visible light, lots of energy, emitted by the sun
14. Albedo the proportion of the incident light or radiation that is
reflected by a surface, typically that of a planet or moon.
15. What does it mean to have a high A surface with a high albedo will reflect more sunlight
or low albedo than a surface with low albedo
16. Dew Point
