What are four physical factors that contribute to Earth's seasons?

Answer 1

The Earth's tilt causes Earth's seasons. The Earth's orbit around the sun also affects the seasons. Landforms on Earth such as mountains play a part in the seasons as do the earth's oceans.

Answer 2

1. Tilt of the Earth's axis: The angle at which the Earth's axis is tilted determines the amount of direct sunlight different regions receive, leading to seasonal variations.
2. Revolution around the sun: The Earth's orbit around the sun causes different parts of the planet to receive varying amounts of sunlight depending on the time of year.
3. axial parallelism: The axis of the Earth remains pointed in the same direction throughout its orbit, which affects the distribution of sunlight on different parts of the Earth.
4. Eccentricity of Earth's orbit: The Earth's orbit is not a perfect circle, but slightly elliptical, which influences the intensity of sunlight received by the planet at different times of the year.
