The increment of one calendar and solar year per revolution (by definition), the changing pattern of different stars and constellations, and, to an extent, planets visible from the night side of Earth, tidal effects, and tiny gravitational perturbations of the Sun and nearby planets' positions. Very tiny.
The Earth's revolution around the Sun does not, by itself, cause the changing seasons. That is a common misconception. The Earth's polar spin axis is not exactly perpendicular to its orbital plane. It is tilted. This accounts for the seasons far more than revolving around the Sun, although neither would work without the other.
The seasons change because of it and the Earths' tilt.
The forces that exist on account of gravity are the cause of Earth's revolution around the Sun.

No, the Earth's revolution around the sun is not related to the rising and setting of the sun on a daily basis, which is caused by the Earth's rotation on its axis.
