it creates the seasons.
The tilting of the Earth on its axis exposes the planet to different levels of sunlight, this in turn causes temperature variations and results in what is known as seasons.
the Earths rotation
Earth's tilting on its axis leads to seasonal changes due variations in the angle (rather than distance) at which light hits.
There would be no four seasons if the earths axis was not tilted.
The seasons
the seasons either get colder or warmer, depending on the tilt of the axis.
the tilting of the earths axis with respect to the sun is a much greater influence on the strength of the sun's rays than the distance between sun and earth

It is the tilting of the earth on its axis, as it orbits the sun, that brings the four seasons to either the northern hemisphere or the southern hemisphere in their turn.
If the Earth stopped tilting on its axis, we would not have our seasons of spring, summer, autumn and winter.
The earths rotation about its axis has no affect on the orbit of satellites about earth. Only their relative velocities and positions are relevant, not their orientation
Very little - just colder.
