Question

earths tropic regions lie within the equatorial latitudes between 0° and 23° north and 0° and 23° south. which of the following best explains why the equatorial latitudes generally experience hot temperatures throughout the year? choose 1 answer: a the equator is miles closer to the sun than other latitudes because of the curvature of earth. b the equator has many more hours of daylight compared to other latitudes. c solar radiation is retained longer by earths surface along the equator. d solar radiation is more intense at the equatorial latitudes.

Explanation:

• Option A: The distance from the equator to the sun due to Earth's curvature is negligible in terms of temperature difference.
• Option B: The equator does not have "many more" hours of daylight compared to other latitudes throughout the year. Daylight hours vary but not to a large extent that would cause such a temperature pattern.
• Option C: There is no significant difference in how long solar radiation is retained by the Earth's surface at the equator compared to other regions that would explain the year - round hot temperatures.
• Option D: Solar radiation is more intense at the equatorial latitudes. The sun's rays hit the equatorial regions more directly (lower angle of incidence), spreading the solar energy over a smaller area compared to higher latitudes. This results in more energy per unit area, leading to generally hot temperatures throughout the year.

Answer:

D. Solar radiation is more intense at the equatorial latitudes.
