What is the primary cause of Earth's seasons according to Newton's Law of Gravity?
A
The gravitational pull of the Moon on Earth.
B
The tilt of Earth's axis relative to its orbit around the Sun.
C
The rotation of Earth on its axis.
D
The varying distance between Earth and the Sun during the year.
Verified step by step guidance1
Begin by understanding that Earth's seasons are not primarily caused by the gravitational pull of the Moon or the varying distance between Earth and the Sun.
Recognize that the primary cause of Earth's seasons is the tilt of Earth's axis relative to its orbit around the Sun. This tilt is approximately 23.5 degrees.
Explain how this axial tilt causes different parts of Earth to receive varying amounts of sunlight throughout the year, leading to the seasons.
During different times of the year, the Northern and Southern Hemispheres are tilted towards or away from the Sun, resulting in changes in temperature and daylight hours.
Conclude that the rotation of Earth on its axis contributes to the daily cycle of day and night but does not directly cause the seasons.
