The seasons on Earth are caused by the tilt of the Earth's axis - they are NOT caused by the differences in the distance from the Sun throughout the year. ... During the winter, the Sun's rays hit the Earth at an extreme angle, and the days are very short. These effects are due to the tilt of the Earth's axis.

For every square meter on the surface of the earth, it will be heated by the Sun at a rate that depends on the 'cosine' of the angle of the Sun above the horizon. ... So, seasonal changes depend on the tilt of the earth's axis because they lead to changes in the amount of heat delivered to a square meter of surface,

The seasons are caused because the Earth is tilted 23.5 degrees on its axis. ... At the equator, there are no seasons because each day the Sun strikes at about the same angle. Every day of the year the equator receives about 12 hours of sunlight. The poles remain cool because they are never tilted in the direct path of...

Thus, for an Earth with NO tilt we will find that the angle subtended between the orbital plane and eqautor disappears. In that case, the "ecliptic" becomes superimposed on the projection of the Earth's equator ... ; You are here: Experts > Science > Space and Astronomy for Kids > Astronomy > Tilt of the Earth's axis.;
