the amount of carbon dioxide present in the atmosphere
|
|
the tilt of Earth on its axis
|
|
The tidal pull of the moon
|
|
the distance between Earth and the sun

Explanation:
Detailed explanation-1: -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 about 365 1/4 days to complete. The earth’s spin axis is tilted with respect to its orbital plane. This is what causes the seasons.
Detailed explanation-2: -Today, the Earth’s axis is tilted 23.5 degrees from the plane of its orbit around the sun. But this tilt changes. During a cycle that averages about 40, 000 years, the tilt of the axis varies between 22.1 and 24.5 degrees.
Detailed explanation-3: -Remind students that the two reasons seasons occur are the tilt of a planet’s axis and its orbit around the sun.
