Hi dear,

Neutral and hot carry the electricla current which powers your electrical devices
-earth/ground wire is an additional wire for safety, it is used to ground metal parts of devices and electrical wiring so thay can't become "live" (dangrous to touch)
- earth/ground is connected to the ground (groundign rods or other grounding electrodes in the soil)
- earth and neutral wires are usually connected together in some part of the electrical wiring (which means that neutral wire is roughly at ground potential)

Hope this helps.
