Answer:
the earth receives only a part of this radiated energy (2 units our of 1,00,00,00,000 units of energy radiated by the sun)
The factor that determines the amount of insolation received is the angle of inclination of the rays. This depends on the latitude of a place. The higher the latitude the less is the angle they make with the surface of the earth resulting in slant sun rays.
