You mean revolving around the sun? Then Kepler's law states that the line from the sun to earth sweeps out equal areas in equal time. Since the earth's orbit is slightly elliptical, that line changes in length over a year. When it's longest, the earth has to move slower to satisfy the law, and vice versa.

Earth revolves around the Sun at a varying speed. The variation is small but not zero. It is due the the Earth's orbit being slightly elliptical and not exactly circular.

If you mean revolving around the sun, then no. The orbit of the earth is slightly elliptical, and physics dictates that the absolute velocity will change as the distance between the earth and sun changes.

Of course not. The Earth's orbit (the path it follows in revolution) is elliptical, it is nearer the Sun (perihelion) at some times than others---Dec. 21being it's closest approach,
Because of this, the gravitational attraction between the Sun and Earth and hence the Earth's orbital speed vary throughout the year.

If you are asking about the orbit around the sun, it's slightly elliptical, so it speeds up near the sun, slows down when away from it. But not much.

My OED says they're the same word. Your question is?

I believe so, that's why there is a constant amount of time for one revolution (one year).
