Is the axis of the earth changing
Witryna27 lut 2010 · As we know, the Earth is presently on a 23.5 degree axis. My "original" thought is that the Earth was once on a 0 degree axis with the whole planet in a relatively temperate zone and then a catastrophe occurred which caused the Earth to be on its present axis. This catastrophe, I believe (origina... WitrynaChanges in axial precession alter the dates of perihelion and aphelion, and therefore increase the seasonal contrast in one hemisphere and decrease the seasonal contrast in the other hemisphere. Left: The change in the tilt of the Earth's axis (obliquity) effects the magnitude of seasonal change. At higher tilts the seasons are more extreme ...
