GY 101 Lab Final Exam UPDATED Questions and
CORRECT Answers
1. Prime Meridian Runs throughterm-53
Greenwich, England @ 0°
2. Kelvin The SI base unit of temperature
used elsewhere
3. Celsius Metric unit for measuring temperature; On this scale water freezes at zero and boils
at 100.
4. Fahrenheit A temperature scale with the freezing point of water 32 degrees and the boiling
point of 212 degrees
5. Tropic of Cancer 23.5 degrees North
6. Equator 0 degrees latitude
7. Tropic of Capri- 23.5 degrees south
corn
8. Prime Meridian PM: Runs through
and International Greenwich, England @ 0°
Date Line ID:@180°
9. When are the March 21 and September 21
equinoxes?
10. When are the june 21 and december 21
soltices?
11. Where is the directly over the equator
sun on the fall

, GY 101 Lab Final Exam UPDATED Questions and
CORRECT Answers
Where is the sun
on the spring
equinox
13. where is the sun Tropic of Cancer
on the summer
solstice
14. where is the sun Tropic of Capricorn
on the winter sol-
stice
15. How to calculate Angle of Incidence = 90°- Lp ± Ls
the angle of ince- • Lp: Latitude of position (where you are)
dence (AOI) • Ls: Latitude of the Sun at the specified date
• + (add) opposing hemispheres
• - (subtract) same hemisphere
16. Stefan-Boltz- The relationship stating that an object emits energy at a rate proportional to the
mann Law fourth power of its temperature, in Kelvins.
17. Wien's Law hotter objects emit radiation at shorter wavelengths, like a shift towards the blue
end of the light spectrum; essentially, the peak wavelength of radiation decreases
as temperature increases.
18. Properties of Infrared light, less energy, reemitted by the Earth
longwave radia-
tion
19. Properties of Visible light, lots of energy, emitted by the Sun
shortwave radia-
tion
20. Albedo
