Have you ever wondered why the Earth is tilted on its axis? This book presents
the Reason for the Inclination of the Earth. "The earth has two principal
motions, one of revolution about the sun, the other of rotation upon an axis.
The revolution about the sun is accomplished in 365 and a quarter days at an
average speed of nineteen miles per second, or thirty-three times the speed of
the swiftest modern projectile. The rotation upon its axis is accomplished in
twenty-four sidereal hours, and since the equatorial circumference of the
earth is nearly 25,000 miles, a point on the earth's equator has a speed of
rotation of over one thousand miles per hour. In form the earth is an oblate
spheroid, a flattened sphere, and the axis about which it rotates coincides
very nearly with the shortest axis of the body. If a plane be passed through
the center of the earth perpendicular to the axis upon which it rotates, not
perpendicular to the shortest axis, this plane will cut the surface in a
circle which is known as the equator...
