Q2. Which of the following statement is true?

A.The insolation received on the Earth varies with latitude: high latitudes receive more insolation than low latitudes.

B.The insolation received on the Earth varies with longitude: east longitudes receive more insolation than west longitudes.

C.The insolation received on the Earth differs between land and ocean: land receives more insolation than the ocean.

D.The insolation received on the Earth mainly depends on Sun's angle of incidence

E.The insolation received on the Earth mainly depends on albedo.

Answer 1

Q1) D.ellipse

Q2) ans: The insolation received on the Earth mainly depends on Sun's angle of incidence

The intensity of solar radiation is largely function of the angle of incidence, the angle at which the Sun's rays falls Earth's surface. If the Sun is positioned directly overhead or 90° from the horizon, the incoming insolation strikes the surface of the Earth at right angles and is highest.
