Earths_Axis

Earths Axis Seasons are caused by the tilt of Earth’s axis of rotation at 23.5 degrees offset of the axis from the direction perpendicular to the Earth’s orbital plane. The direction of the rotational axis stays nearly fixed in space, even as the Earth revolves around the sun once a year. As a result, when the Earth is at a certain place in its orbit, the Northern hemisphere is tilted towards the sun and experiences summer. Six months later the Northern hemisphere is tilted away from the sun and experiences winter. The seasons are reversed for the Southern hemisphere. Many factors change due to the tilt of the Earth, whether it is at the normal 23.5 degrees, at 45 degrees or at no tilt at all. The tilt of the Earth has a major effect on the seasons around the world and the amount of daylight that each particular geographic location receives. If the Earth were not tilted, the days would act like the equinox at all geographic locations. Thus, each area would experience 12 hour days and 12 hour nights.
