The amount of insolation received at a place on the surface of the earth depends upon:
-
- its climate
- the longitude of the place
- its latitude
- the altitude of the place
Correct Option: C
Insolation is a measure of solar radiation energy received on a given surface area in a given time. It mainly depends on two factors: (a) the angle at which the Sun’s rays strike the Earth, and (b) the length of time of exposure to the rays. Both of these factors are controlled by the latitude of the location and time of the year (Physical Geography Strahler &Strahler).
