It depends where you measure the circumference. The earth is an oblate spheroid - so it has a larger circumference around the equator than round the poles - a bit like a satsuma shape . This is due to the spin of the earth - centripetal force causes the central equator region to bulge slightly outwards - so yes it will be a slighly bigger circumference than it was when originally formed.

The earth was not created in a single "bang" event. The earth formed slowly over millions of years from the accretion of material left over when the sun formed (by most theories, from the debris of a previous star that had gone supernova). The accretion process caused a small amount of material to gather more and more material from the primordial cloud of gas and dust until the earth finally reached something like its present form. The earth continues to accrete material slowly (meteors may burn up, but the matter still becomes part of the earth, and dust continually enters the atmosphere). This process is slow enough that the growth of the earth's circumference is probably not measurable.

The fact that the universe is expaniding refers to the fact that the distance between objects such as stars and galaxies is increasing, not their size.

The earth was formed over time from accreation of let overs from the formation of the sun, This material formed a larger but less dense planet earlier in time, but the gravitational forces of the mass pulled it into a tighter and tighter ball so the diameter got somewhat smaller over time. That process has ended although we still have plate techtonic phenomenon going on so mountains rise and fall making small changes in the earth's size. We also pick up tons of space debri every day which adds to the mass of the earth and hence to its size, however small that may be.

It wasn't created, It accreted. It was probably somewhat larger toward the end of the accretion phase. Things tend to shrink when they cool. The earth cooled once the bombardment of major asteroids stopped. A solid crust formed. Of course the earth picks up perhaps a couple of hundred tons a day of meteoric material. Whether this is enough to build up its volume to greater than its original size, I doubt if anyone knows.

Yes, but only if you include man-made structures into the equation. This is because for every inch a mountain gains, an inch of the seabed is lost due to tectonic plate activity. We have, however, made hollow structures that have more volume in proportion to mass. This would easily upset the balance.

No, would have major changes in the earth surface but not probably i the circumferance

Over several hundred million years rocks and dust were drawn in and gradually the Earth increased in mass and size.
So it did grow, and its still growing, very slowly. Many tons of dust from burnt up asteroids and satellites drops to Earth every day.

I say yes!The universe is constantly expanding.Everything in the universe including the planets,stars and galaxies are expanding.

Likely. I believe in evolution and that everything changes.
Interesting question and I'm giving you a star for that.

Yes, the universe is expanding. Everything in the universe.
