Which of the following causes seasons on Earth?
A) the variation in proximity of the Earth to the sun at different times of the year
B) the constant tilt of the Earth, combined with its orbit around the sun
C) the distance between the Earth and the sun in winter versus in the summer
D) the variation or wobble of Earth's tilt during the year

Question

Quizplus · Accepted Answer

The constant tilt of the Earth's axis combined with its orbit around the sun causes different areas of the planet to receive varying amounts of direct sunlight throughout the year, leading to the seasons. The variation in proximity of Earth to the sun (A) and the distance between the Earth and the sun during different seasons (C) are related to the seasons, but they are not the primary cause. The variation or wobble of Earth's tilt during the year (D) is known as axial precession, but this occurs on a much longer timescale and does not directly cause the seasons.
