1. 23d 26' 22" (23.4394 degrees) north 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 hemisphere is tilted
towards the sun to its maximum extent.: Tropic of Cancer
2. Equator: an imaginary line drawn around the earth equally distant 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) south of the Equator and marks the most
southerly latitude at which the sun can appear directly overhead at noon. This
event occurs at the December solstice, when the southern hemisphere is tilted
towards the sun to its maximum extent.: Tropic of Capricorn
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 is: June 20th, Tropic of Cancer
7. Winter Solstice and where the sun is: December 21-22, Tropic of Capricorn
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 temperature, 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 or low albedo: A surface with a high albedo will reflect
more sunlight than a surface with low albedo
16. Dew Point: the temperature the air needs to be cooled to (at constant pressure) in order to achieve a relative
humidity (RH) of 100%.More stable than relative humidity.
