Question

Will the two sides of a mountain front recieve the same amount of sun rays? what could be the reason?

Answer 1

Since Earth is nearly spherical and it's axis is tilted 23.5° from the plane of its orbit around the Sun, the sun’s rays strike the surface at different angles in different regions depending on the latitude of the region. The higher the latitude, the less is the angle that the sun's rays make with the surface of the earth. Hence, the polar regions receive slanting rays of sunlight.
