Question

Introduction. What would happen to our seasons if Earth's axis tilt were different from its actual 23.5 degree? This activity will help you answer this question and will also help you understand seasons on planets that have axis tilts different from Earth's. As you examine the diagrams in parts A and B. keep in mind that Earth is always rotating, even though the diagrams do not show this rotation because they are not animated. Each of the following figures shows Earth with a different axis tilt. (Assume that Earth's rotation period is unchanged.) Each also shows a person located in Florida (not to scale). Rank the figures based on how much time the person spends in daylight during a 24-hour period, from most to least. The following figures are the same as those from Part A. This time, consider the seasonal differences that occur as Earth orbits the Sun with the different axis tilts. Rank the figures on the basis of the seasonal temperature differences you would expect between summer and winter, from the one with the most extreme seasonal differences to the one with the least extreme. To rank items as equivalent, overlap them.

Explanation / Answer

a) Tilt = 0, no change in length of day or night anywhere onearth. No seasons b) Tilt = 23.5, south pole getting more light than north pole. This the winter solstace north of the equator. c) Tilt = 90, No light ever gets to the norhternhemishpere. No seasons, but very cold in the north, very hotin the southern hemispere. d) Tilt = 23.5, north pole getting more light than the southpole. This is summer solstace north of the equator e) Tilt = 45, south pole getting more light than the northpole. Very short days in the northern latitudes, extremeseasons.
Day length in FLA, from longest to shortest: d a b e c
Part B The two at 22.5 are equal as they swap as earth goes aroundthe sun 0 has no seasons 45 has extreme seasons 90 has no seasons, but drastic weather extremes from north(cold) to south( hot)
