A
The rotation speed of Earth changing throughout the year.
B
The gravitational pull of the Moon affecting Earth's climate.
C
The varying distance between Earth and the Sun during the year.
D
The tilt of Earth's axis relative to its orbit around the Sun.
Verified step by step guidance
1
Understand 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 seasonal temperature changes.
Recognize that the primary cause of seasonal changes is the tilt of Earth's axis, which is approximately 23.5 degrees relative to its orbital plane around the Sun.
Explain that as Earth orbits the Sun, this axial tilt causes different parts of Earth to receive varying amounts of sunlight at different times of the year, leading to seasons.
Clarify that during summer in a given hemisphere, that hemisphere is tilted towards the Sun, resulting in longer days and more direct sunlight, which increases temperatures.
Conversely, during winter, the same hemisphere is tilted away from the Sun, leading to shorter days and less direct sunlight, which decreases temperatures.
