Q126
Although the polar regions radiate away more heat energy than they receive by insolation in the course of a year, they are prevented from becoming progressively colder each year by the:
A.
Conduction of heat through the interior of the earth
B.
Concentration of earth's magnetic field lines at the poles
C.
Circulation of heat by the atmosphere and oceans
AnswerD.
The insulating properties of snow
E.
Release of latent heat to the atmosphere when polar ice melts
Answer: Option C
Solution
Answer: Option C
Solution:
A radiation inversion is most commonly observed: just above the ground. Although the polar regions radiate away more heat energy than they receive by insolation in the course of a year, they are prevented from becoming progressively colder each year by: the circulation of heat by the atmosphere and the oceans.
