The earth's radiative equilibrium temperature is:
A. The temperature at which the earth is absorbing solar radiation and emitting infrared radiation at equal rates
B. The temperature at which the earth is radiating energy at maximum intensity
C. The average temperature the earth must maintain to prevent the oceans from freezing solid
D. The temperature at which rates of evaporation and condensation on the earth are in balance
Answer: Option A
Solution(By Examveda Team)
This is radiative equilibrium, energy balance. The temperature at which this occurs is about 0 F. That is called the temperature of radiative equilibrium. You might remember this is the figure for global annual average surface temperature on the earth without the greenhouse effect.This Question Belongs to General Knowledge >> Environmental Science
