Answer 2

If you're talking about electrical terms, the differences are usually very small and the terms are often used interchangeably.

`Earth' usually indicates that the `ground' of your device is physically connected to the Earth, but a device can certainly have a `ground' without touching the Earth.

In the simplest case, `ground' simply means that this is the voltage that all other voltages in a device are measured against. (It often also happens to be connected to the frame/case of the device, and might be wired to the actual ground of the Earth.)

In any event, read the three wikipedia pages below -- they go into much more detail.

Answer 3

In electrical terms ground and earth are different names for the same thing and = 0 volts

Neutral is the common point in a three phase system. If the load on each phase is balanced the neutral will be at 0 volts, however this is rarely the case. If you measure between earth and neutral you will find a small voltage. if the in-balance is bad it could be as much as 5 volts.

It's tempting to put a step-up transformer across the earth and neutral lines and get free electricity. It's illegal and you would have no control over the voltage you could achieve.
