Question

questions 1 through 3 refer to the following. the axis of earth in relation to the sun is tilted at a 23.5 degree slant, as illustrated in the diagram below. use the diagram below to answer the next three questions. artic circle tropic of cancer equator tropic of capricorn antarctic circle n 66°33 direct sunlight

Explanation:

• Option A: The Tropic of Cancer has a shorter day (as per the diagram's tilt) and higher solar radiation intensity. There is an inverse relationship - shorter days (less daylight hours) can lead to higher intensity as the sun's rays are more concentrated (e.g., in polar regions during certain times, less daylight but when the sun is up, rays can be intense).
• Option B: The Tropic of Capricorn, in this diagrammatic situation (assuming Northern - hemisphere summer - like tilt), would have longer nights (shorter days) but lower solar radiation intensity (as the sun is not directly overhead). A direct relationship claim is wrong.
• Option C: The equator has 12 - hour daylight throughout the year, but it does not have the greatest solar radiation intensity. Areas closer to the subsolar point (e.g., Tropic of Cancer in this case) have higher intensity.
• Option D: The Tropic of Cancer has higher solar radiation intensity (not lower) as the sun is closer to being directly overhead (based on the tilt and direct sunlight shown in the diagram).

Answer:

A. The Tropic of Cancer has a shorter day and higher solar radiation intensity because there is an inverse relationship between length of day and radiation intensity.
