Thx can you check my "Moon science" post plz?
B. Gravity
The factor that has the biggest impact on Earth's seasons is Earth's tilt on its axis. This means that the correct answer is option C.
To understand why Earth's tilt on its axis affects the seasons, we can look at how sunlight hits the Earth. As the Earth orbits around the Sun, there are two important factors to consider: Earth's revolution and Earth's tilt.
Earth's revolution refers to its yearly journey around the Sun. This journey takes approximately 365.25 days to complete, which is why we have leap years to account for the additional quarter of a day.
Earth's tilt on its axis is the angle at which Earth's axis is tilted in relation to its orbit around the Sun. The Earth's axis is tilted at an angle of about 23.5 degrees. This tilt remains constant as Earth revolves around the Sun.
The combination of Earth's tilt and revolution is what causes the seasons. When the Northern Hemisphere is tilted towards the Sun, it receives more direct sunlight, leading to summer in that hemisphere. At the same time, the Southern Hemisphere is tilted away from the Sun, resulting in winter. As the Earth continues its orbit around the Sun, the tilt changes the hemisphere that receives more direct sunlight, causing the seasons to change.
Earth's elliptical orbit, mentioned in option B, does have an impact on the Earth-Sun distance, but it does not have as significant of an effect on the seasons as Earth's axial tilt. The distance from the Sun, mentioned in option D, also affects the amount of sunlight received, but it is not the primary factor that causes the seasons.
Therefore, the biggest impact on Earth's seasons is Earth's tilt on its axis, making option C the correct answer.
