Question

1. which location receives 12 hours of daylight and 12 hours of darkness? a. a b. b c. c d. d 8. at which location on december 21 is the sun directly overhead at solar noon? a. a b. b c. c d. d 9. if the tilt of earths axis were decreased from 23.5° to 15°, winters in the northern hemisphere would a. warmer, and summers would become cooler b. warmer, and summers would become warmer c. cooler, and summers would become cooler d. cooler, and summers would become warmer 10. which location in earths orbit represents the first day of spring in the northern hemisphere? a. a b. b c. c d. d base your answers to questions 11 through 13 on the diagram and data table below. the diagram shows the suns apparent paths as viewed by an observer located at 50°n

Explanation:

1. Locations on the equator receive 12 hours of daylight and 12 hours of darkness throughout the year. On December 21, the sun is directly overhead at the Tropic of Capricorn. But the location that always has 12 - hour days and nights is the equator.
2. On December 21, the sun is directly overhead at the Tropic of Capricorn (23.5°S).
3. The tilt of the Earth's axis affects the seasons. A decrease in the tilt would make the differences between summer and winter less extreme. Winters in the Northern Hemisphere would become warmer and summers would become cooler as the angle at which sunlight hits the Earth would vary less throughout the year.
4. The vernal equinox marks the first day of spring in the Northern Hemisphere. In the Earth - Sun orbit diagram, the position corresponding to the first day of spring in the Northern Hemisphere is typically when the Earth is in a position where the sun's rays are directly over the equator moving northward.

Answer:

1. Equator (not in options but conceptually correct, if we assume closest is the location with consistent 12 - hour days which is not clearly indicated in options)
2. Tropic of Capricorn (not in options but correct location; if we have to choose from options, no correct option as none represent Tropic of Capricorn)
3. b. warmer, and summers would become cooler
4. (No clear option indicating vernal equinox position in the given options)
