its 66.5 degrees
The non-perpendicularity of the Earth's rotational axis relative to the ecliptic plane
is the cause of Earth's seasons, and of the variation in the length of night and day
during the year at any single latitude.
The major effect is seasons. As the Earth moves round its orbit the part which points at the Sun and therefore gets most heat and light changes from North to South and back.
The degree of tilt explains the location of both Tropics and Polar Circles.
Edit; It is important to understand that the axis of the Earth remains directed to the same point in outer space at all seasons as the Earth moves around the Sun. This point is vital to the changing Seasons. It is not like a spinning top as it loses its intrinsic stability and wobbles across the surface. It is tilted at the 66.5 degrees to the Ecliptic and the velocity and mass of its rotation ensure that it remains in a stable direction at all times. If the Moon vanishes, we may have to revise this.
Earth's Tilt Is the Reason for the Seasons!
During the year, the seasons change depending on the amount of sunlight reaching the Earth as it revolves around the Sun.
The seasons are caused as the Earth, tilted on its axis, travels in a loop around the Sun each year. Summer happens in the hemisphere tilted towards the Sun, and winter happens in the hemisphere tilted away from the Sun. As the Earth travels around the Sun, the hemisphere that is tilted towards or away from the Sun changes.
The earth's axis of rotation isn't exactly perpendicular (straight up and down) to the plane of its
orbit around the sun. But it always points in the same direction ... the north pole pointing close to
the North Star. Since it always points in the same direction, the north pole leans toward the sun
when we're on one side of it, and away from the sun six months later, when we're around on the
other side of the sun.
The earth's axis of rotation makes an angle of roughly 66.5 degrees with the plane of
the earth's orbit around the sun.
The axis doesn't wiggle or wobble in the course of a year, and is always pointed toward
the same point among the distant stars. So at different times throughout the year, it will
appear to tilt toward the sun, or away from the sun, or neither.
The Earth tilts about 23° (the axis tilt with respect to the plane of the Earth orbit).
The tilt is sych that in June the northern hemisphere is tilted towards the sun and in December the northern hemisphere is away from the sun. (The Earth is actually closes to the Sun aroound January 3rd- so it it the tilt and not the distance to the Sun that gives us seasons).
During formation. The motes of dust that first came together impacted each other at oblique angles and set each other spinning and the larger rocks each put their spins together whenever they would fuse or sent each other spinning in new ways if they bounced off of each other.
The physics of angular momentum gives us exact numbers of how fast and in what direction the contents of our solar system should spin (the net value- how much all added together,) and gives us the expectation that the majority of it should end up spinning in mostly the same direction and nearly the same plane, aside from the wobbles in any unbalanced object that spins.
From different angles, the view from Earth depends. For example, if you were in a certain place, and the Earth rotated, then you looked at the moon, it would be in a different phase. The moon is also moving, so when the two move, every night when you look up the moon should be slightly different because of our angle.
Another example is the Sun. When Summer goes to Autumn to Winter, the Sun sets in and rises in the opposite it was before. The Sun does not move, so its our angle caused from rotation of Earth that causes our change of view.
No. The earth always tilts the same way but because of the revolution around the sun, the north end of the axis points towards the sun (north hemisphere's summer) and then it revolves until the north end of the axis is pointing away from the sun. (north hemisphere's winter) When neither the north or south end of the axis is pointing towards the sun, its either spring or fall.
Earth's rotation creates a sense of the sun's movement
Why do we see differences in the appearance and movements of the Sun and Moon from Earth
Because the earth is a ball, and the sun is the only light source responsible for day and night, the earth can only be illuminated on one side at a time. Luckily, the earth spins so that every side of the earth gets a piece of sunshine. The rotation of the earth is what causes day and night.
The Earth rotates itself as is revolves around the Sun. Earth is said to have a Prograde rotation by only looking at the North pole. Unlike Earth, Venus has a Retrograde rotation. A Prograde rotation is counterclockwise, while a Retrograde rotation is clockwise. So, from Earth, the sun looks like it rises from the East and rests in the West, but on Venus, the sun rises from the West and sets in the East. Apparently, the answer is that Earth itself rotates counterclockwise as it revolves around the sun. (of course the sun doesn't move, nor is the Earth at the center of the galaxy)
Rotation I think ?
When the earth moves, the sun is left behind, so half of the earth is not facing the sun. Dumbo
No. Earth orbits the sun, not the other way around. Earth's orbit depends on the mass of the sun, not Earth's rotation. Earth's rotation does, however, give the appearance that celestial objects revolve around it.

I am not an a*****e like you al who have answered these questions
The rotation of the Earth produces days and nights, because different areas are illuminated at different times. The orbit of the Earth creates years because the period of rotation dictates how long it takes for all the seasons to pass by. The rotation rate of the Sun does not affect either the days or the years of Earth.
When there is slow rotation and orbit around the sun , day and night in earth is affected not only that but due to slow rotation seasons in earth also changes slowly .As there is sloe season change in directly affects on agriculture on earth.
It is not the Sun that Is moving across the sky, although it does look like it. No it is because Earth's rotation causing it to look as if the Sun was moving and not us. Our planets rotation makes it look as if the sun rises in the east, because we have a rotation of west to east, which causes it that appearance.
If there is any effect at all, it would need to be a very tiny one. The only way that the Earth's rotation might affect the Sun would be in the way the Earth's rotation generates Earth's magnetic field. Our magnetic field affects the way that coronal mass ejections, huge bubbles of ionized gas from the Sun, behave when they get close. But the Sun has a magnetic field of its own, much stronger than the Earth's field, and it is unlikely that the Earth's magnetic field would affect the Sun or the Sun's magnetic field in more than a minuscule fashion.
The rotation of the earth causes the appearance of the changing location of the sun across the sky. The change in shadows caused by sunlight are an extention of the geometery involved.
1. Rotation (earth rotates on it's axis) 2. Orbit (earth orbit's arount the sun)
Rotation around the north/south axis causes days, orbit around the sun causes years. penis
Rotation and tilt affect the amount of solar energy the earth receives because when the earth is tilted and or rotating, one specific part of the earth is more directed towards the sun then all the others.
