Question

why do the poles receive less solar radiation than the equator?
a the suns rays strike at a low angle and only during the summer
b the suns rays strike directly but only during summer
c the suns rays strike at a high angle in the winter and directly in the summer
d none of the above

Explanation:

To determine why the poles receive less solar radiation than the Equator, we analyze each option:

• Option a: The Sun’s rays strike the poles at a low angle (due to Earth’s curvature and axial tilt), and polar regions have long periods of darkness (e.g., polar night) in winter, so solar radiation is limited, especially in non - summer months. This aligns with the reason for less solar radiation.
• Option b: The Sun’s rays do not strike the poles directly (direct rays are at the Equator or tropics), so this is incorrect.
• Option c: The Sun’s rays do not strike the poles at a high angle (low angle is typical) and do not strike directly, so this is incorrect.

Answer:

a. The Sun's rays strike at a low angle and only during the summer
