The Earth Is Spherical,which Causes Differences in the Intensity of Solar

question 21

Multiple Choice

The Earth is spherical,which causes differences in the intensity of solar radiation at different latitudes (refer to Figure 43.14 ) .The Earth is also tilted on its axis at a 23.5 ^$\circ$ angle.How do you think this tilt affects the intensity of solar radiation?

• A)In the Northern and Southern hemispheres,equal latitudes receive the sun's rays at equal angles year round.
• B)The Northern hemisphere has a lower intensity of solar radiation than the Southern hemisphere because it is tilted away from the Sun year round.
• C)The sun's rays strike the Northern hemisphere more obliquely during its summer months and less obliquely during its winter months.
• D)The Northern hemisphere has a higher intensity of solar radiation than the Southern hemisphere because it is tilted toward the Sun year rounD.
