We have no real idea of what caused the Earth to form in the orbit that it did (rather than one a little closer to the Sun or a little further away) but the speed of the Earth in its current orbit is fixed by its distance from the Sun. A closer orbit would be faster; a more distant orbit would be slower.
Nor do we know why the Earth spins at its current rate. These things happened billions of years ago. We may NEVER know what happened way back when to cause things to be the way they are.
Yes... yes it does. For that matter, the Earth's heat causes some atoms to move so fast that they "crash into each other."
Pluto moves around the Sun, not the earth
Very gradually
because when it was first started it moved very fast later the sun and the moon slowed it down.
250kilometers per second
The space shuttle needs to go fast in order to reach orbit around the Earth. By going fast, the shuttle can overcome the gravitational pull of the Earth and enter into a stable orbit where it remains in space. This speed is necessary to counteract the pull of gravity and maintain a continuous state of freefall around the Earth.

I think it's because the earth going round, too fast......
they move in a fast way then they stop then they go then they stop so they move how they want to.
If you mean, in its orbit around Earth, that's about 1.022 km/sec.
If they crash into Earth, an enormous amount of energy can be released, since they move very fast.
