This titled position of the earths axis is known as inclination of the earths axis. The earth's rotation axis makes an angle of about 66.5 degrees with the plane of its orbit around the sun, or about 23.5 degrees from the perpendicular to the ecliptic plane what is the scientific reason for the inclination of earth's rotation axis? and what will happen if the inclination angel changed?

The axial tilt, or obliquity, of a planet is a constantly (but slowly) changing thing. There is no one particular reason why a planet should have a particular axial tilt, but whatever the initial tilt is, eventually the tidal forces between moons, planets and the central star tend to cause obliquities to oscillate in a damped manner, eventually leading to a stabilized, equilibrium value. If the angle changed, seasons would have a different character. If the obliquity was reduced, the seasons would become harder to differentiate between each other because winter wouldn't be as cold and summer wouldn't be as warm. The opposite would occur if the angle was larger. It would be interesting to observe obliquities of extrasolar planets and perform some statistics on them. Unfortunately, this is rather difficult to do.
