Which of the following is most responsible for the changes of the seasons on Earth according to Newton's Law of Gravity?
A
The tilt of Earth's axis relative to its orbit around the Sun
B
The rotation of Earth on its axis
C
The gravitational pull of the Moon
D
The distance between Earth and the Sun
Verified step by step guidance1
Understand that the problem is asking about the cause of seasonal changes on Earth, which is a concept related to Earth's motion and orientation in space.
Recall that Newton's Law of Gravity describes the gravitational attraction between two masses, such as Earth and the Sun, but it does not directly explain the seasons.
Recognize that the tilt of Earth's axis relative to its orbit around the Sun is the primary reason for the seasons. This tilt causes different parts of Earth to receive varying amounts of sunlight throughout the year.
Consider the other options: The rotation of Earth on its axis causes day and night, not seasons. The gravitational pull of the Moon affects tides, not seasons. The distance between Earth and the Sun does vary slightly, but it is not the main cause of seasonal changes.
Conclude that the tilt of Earth's axis is the most responsible factor for the changes of the seasons, as it affects the angle and intensity of sunlight received by different parts of Earth during its orbit around the Sun.
