Phebe Posted July 30, 2005 Report Share Posted July 30, 2005 OK, so the earth is on a tilt, (23 1/4 degrees? I think) What if this changed. How do you think it would affect earth not just climatically? What if it became perfectly aligned? Quote Link to comment Share on other sites More sharing options...
UncleAl Posted July 30, 2005 Report Share Posted July 30, 2005 23.4 degrees from the ecliptic plane. Straight up you have no seasons - perpetual equinox. Insolation then depends on latitude. Canada and Siberia get it good and hard. More tilt and the seasons are more extreme. In that case, track Arctic and Antarctic circles plus Tropics of Capricorn and Cancer as the Equator cools. http://www.carnaval.com/precession/http://www.museum.state.il.us/exhibits/ice_ages/tilt_graph.htmlhttp://aa.usno.navy.mil/faq/docs/seasons_orbit.html Tip it 90 degrees and the poles get great yarblockos of winter and summer as the equator perpetually freezes Quote Link to comment Share on other sites More sharing options...
