The Northern Hemisphere is most tilted toward the sun on the________.
- a. March equinox
- b. September equinox
- c. June solstice
- d. December solstice
Introduction: The Earth rotates in an elliptical path around the sun one full time per year. Seasonal changes occur because the earth is tilted at 23 degrees on axis. The seasonal changes depend on the amount of sunlight that reaches the parts of the earth.
Reason for correct answer:
In June solstice, the northern hemisphere has the longest day and receives most sunlight directly; hence, the northern hemisphere is most tilted toward the sun.
Option c. is given as “June solstice”. Therefore, option c. is correct.
Reason for incorrect answer:
Option a. is given as “March equinox”. In March equinox, the day length and night length is equal everywhere and sunlight directly falls on the equator. Therefore, option a...
