Geography Worksheet 2

Question 1

Greenhouse Law formula is expressed below, where C is ______ and F is ______:

ΔF = α Ln(C/C0) a.

a.carbon dioxide (CO2) concentration, the radiative forcing

b. carbon monoxide (CO) concentration, the frictional forcing

c. the centrifugal forcing, the solar forcing

d. carbon dioxide (CO2), the magnetic forcing

e. both b and c

· Question 2

· At the beginning of the industrial revolution in 1850, the CO2 concentration was 280 ppm. Today, it is 416 ppm. 1) If CO2 concentration reaches 500 ppm, how much extra radiative forcing is the Earth’s surface receiving, relative to 1850? 2) What is the equivalent temperature change?

· ΔF (Wm-2) = α ln(C/C0), ΔT(K) = λ*ΔF

· α = 5.35, λ = 0.8 per (Wm-2)

c. a negative feedback

d. a neutral feedback

Question 11

Positive internal Earth system feedbacks:

a. Ekman

b. Geostrophic

c. Kinetic geo-rotation

a. It remained constant.

b. It increased.

c. It decreased.

d. No change.

Question 14

Though Nitrogen (N2) is a major gas in our atmosphere, why is it not a greenhouse gas?

a. Molecular structure is symmetrical, and does not have a charge imbalance.

b. Molecule structure is naturally very electrically lopsided.

c. Molecule vibrates in response to infrared light frequency.

d. None of the above.
