Question

Quizplus · Accepted Answer

The changing angle at which sunlight reaches the Earth causes the variation in the duration and intensity of sunlight that the Earth's surface receives during different parts of the year in the different hemispheres. This angle is directly related to the tilt of Earth's axis as it orbits around the Sun, which brings us to part B. Daylight hours also vary as a result of the Earth's tilt, so the length of the day contributes to the seasonal changes. Distance between Earth and the Sun also affects how much heating or cooling we receive, but this effect is negligible compared to the other two factors. Therefore, both parts B and C are responsible for the seasonal changes on Earth.
