Answer to Question #121498 in Physics for ran li

Question

The average amount of insolation at the poles is less than at the equator due to:
a) the angle of incidence of incoming solar radiation
b) the angle of inclination of Earth
c) the angle of refraction of incoming solar radiation
d) the angle of reflection of incoming solar radiation

Answer 1

The average amount of insolation at the poles is less than at the equator due to the angle of incidence of incoming solar radiation, which is the consequence of the angle of inclination of Earth, and angle of reflection of incoming solar radiation.
