Question

how seasons occur ? Give reasons.​

Answer 1

Answer:

Earth's tilted axis causes the seasons.

Explanation: As the Earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires 365 1/4 days to complete. Earth's spin axis is tilted with respect to its orbit plane. This is what causes the seasons.

Answer 2

The phenomenon of the season occurrence is described based on:

1. Earth's revolution: The earth takes three hundred sixty-five and one-fourth days orbiting the sun, causing summertime in areas that are directly faced with the sun and wintertime in those heading angularly to the sun.
2. Earth's rotation: The earth travels from the western direction to the east side, allowing sunlight to fall on different parts of the planet for varying amounts of time. Seasons, therefore, happen by the cyclical receipt of sunlight on certain regions and the devoid of sunshine on other parts.
3. Earth's tilt: The tilt at sixty-six and 1/2' makes no same region of the planet receives sunlight throughout the year. Summer happens by the hemisphere's tilt pointing to the sun, whereas winter is caused by the hemisphere's tilt pointing far from the sun.

• Hence, the season occurs.
