in the Earth's orbit--the path along which it moves through space--affect
its closeness to the sun, and thus the amount of solar energy reaching
the Earth's atmosphere and surface. Changes in the Earth's orbit
could include changes in
or shape of the Earth's orbit around the sun, which can be elliptical
to nearly circular
or wobbling of the Earth's axis
- the tilt of the
Earth rotating about its axis as it orbits the sun.
Theory states that changes in eccentricity, precession, and the tilt
of the earth's axis may be responsible for global climate change
over geologic time.
