Which of these characteristics of the earth best explains the change of seasons?
A
The diameter of the earth
B
The tilt of Earth’s axis
C
The speed of the earth’s rotation
D
The distance from the earth to the sun.
Explanation: 

Detailed explanation-1: -The earth’s spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth’s axis points towards the sun, it is summer for that hemisphere. When the earth’s axis points away, winter can be expected.

Detailed explanation-2: -Earth’s axial tilt (also known as the obliquity of the ecliptic) is about 23.5 degrees. Due to this axial tilt, the sun shines on different latitudes at different angles throughout the year. This causes the seasons. Uranus has the largest axial tilt in the solar system.

Detailed explanation-3: -The answer is “Earth’s rotation causes day and night, not the seasons.” The seasons are caused by the tilt of the Earth’s rotational axis away or toward the sun as it travels through its year-long path around the sun.
