Yes, even if Earth's orbit around the Sun were elliptical instead of circular, it would still experience seasons due to its axial tilt. The seasons on Earth are primarily caused by the tilt of its axis relative to its orbit around the Sun, not by the shape of its orbit.
Currently, Earth's axis is tilted about 23.5 degrees relative to its orbital plane. This tilt causes different parts of the planet to receive varying amounts of sunlight throughout the year as Earth orbits the Sun. When a hemisphere is tilted towards the Sun, it receives more direct sunlight and experiences summer. Conversely, when that hemisphere is tilted away from the Sun, it receives less direct sunlight and experiences winter. The other two seasons, spring and autumn, occur during the transitional periods between summer and winter.
If Earth's orbit were more elliptical, the distance between the Earth and the Sun would vary throughout the year. This would affect the intensity of sunlight reaching Earth, as the planet would be closer to the Sun during one part of its orbit and farther away during another. However, the axial tilt would still be the primary factor determining the occurrence of seasons.
In summary, the shape of Earth's orbit, whether circular or elliptical, does not significantly impact the occurrence of seasons. The axial tilt remains the primary driver of seasonal variations on our planet.
