Question

equator) to the tropic of capricorn (23.5° south of the equator). the tropical zone receives direct sunlight all year round, so its climate is sunny and hot. the polar zones are the regions that surround the north and south poles, extending from the poles to 60° north and 60° south of the equator. they receive little direct sunlight and have a frigid climate. in between the tropical and polar zones are the temperate zones. these regions have more moderate climates that vary with the seasons.
based on the passage, which of the following is correct?
choose one option
a there is only one polar zone on earth.
b the sun reaches all areas of earth equally.
c the polar zone extends to the tropic of capricorn.
d the northern temperate zone extends from 60° to 23.5° north of the equator.

Explanation:

• Option A: The passage states "the polar zones are the regions that surround the North and South Poles", so there are two polar zones, not one. This option is incorrect.
• Option B: The passage mentions that the tropical zone receives direct sunlight all year round, the polar zones receive little direct sunlight. So the sun does not reach all areas of Earth equally. This option is incorrect.
• Option C: The polar zones extend from the poles to \(60^{\circ}\) north and \(60^{\circ}\) south of the equator, while the Tropic of Capricorn is \(23.5^{\circ}\) south of the equator. So this option is incorrect.
• Option D: The tropical zone is from \(23.5^{\circ}\) north to \(23.5^{\circ}\) south of the equator, the polar zones are from the poles to \(60^{\circ}\) north and \(60^{\circ}\) south. So the northern temperate zone (between tropical and polar zones) extends from \(60^{\circ}\) to \(23.5^{\circ}\) north of the equator. This option is correct.

Answer:

D. The northern temperate zone extends from \(60^{\circ}\) to \(23.5^{\circ}\) north of the equator.
