1. How would the seasons be affected if the Earth's axis were not inclined 23 1/2 degrees from the plane of the ecliptic, but were instead perpendicular to that orbital plane?

We have all been taught that the seasons are caused by the tilt of the Earth's axis of rotation - the 23.4Â° offset of the axis from a 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 each year. As a result, when the Earth is at a certain place in its orbit, the northern hemisphere is tilted toward the Sun and experiences summer. Six months later, when the Earth is on the opposite side of the Sun, the northern hemisphere is tilted away from the Sun and experiences winter. The seasons are, of course, reversed for the southern hemisphere. The solstices mark the two dates during the year on which the Earth's position in its orbit ...

#### Solution Summary

This solution provides the answer to the question: How would the seasons be affected if the Earth's axis were not inclined 23 1/2 degrees from the plane of the ecliptic, but were instead perpendicular to that orbital plane? Supplemented with a highly informative article on the earth's orbits which extends this response.
