23.5 degrees from the perpendicular.
The revolution of the earth defines its tilt. The "tilt" is the angle between the axis of rotation of the earth and the axis of its revolution around the sun. Both these axes must exist to define the tilt. If the earth did not rotate on an axis of its own, or if it did not revolve around the sun, it would be meaningless to speak of a tilt.
its earths tilt on its axis orbiting the sun
The same way it affects most of earth. The seasons are caused by the tilt of the earth's axis relative to the plane of its orbit.
The tilt of the Earth's axis in relation to the plane of its orbit.
About 23.5 degrees
The tilt of the Earth's axis is why there are seasons. =)
They change by the tilt of the earth's axis!
The tilt of the earth's axis is called ecliptic. The tilt of the earth's axis will vary in most cases between 22.1 and 24.5 degrees.
23° 26' 21.4119"
Mercury's axis tilt is 0°. Venus' axis tilt is 177.4°. Earth's axis tilt is 23.5°. Mars' axis tilt is 25.2°. Jupiter's axis tilt is 3.1°. Saturn's axis tilt is 25.3°. Uranus' axis tilt is 97.8°. Neptune's axis tilt is 28.8°. Pluto's axis tilt is 122.5°.
the seasons either get colder or warmer, depending on the tilt of the axis.
Earth's tilt
The tilt of the Earth's axis.
23.5 degrees from the perpendicular.
The "tilt" is related to Earth's axis of rotation; both the axis of rotation and the tilt would be undefined if there were no rotation.
