Question

When Earth's orbit becomes more circular (i.e., compared with a more elliptical orbit), the distance between Earth and the sun at aphelion _______. This change leads to a(n) _______ in the intensity of solar radiation at aphelion, and thus _______ seasonality.

A)

increases; increase; increases

B)

increases; increase; decreases

C)

decreases; increase; increases

D)

decreases; increase; decreases

Explanation / Answer

aphelion is the point where distance is maximum.

so if it becomes more circular then distance will decrease.

so intensity will increase.

and intensity will be more uniform.

so seasonality will decreases.

Ans: (D) decreases, increases, decreases.
