Answers:
DO NOT do the above - call a licensed electrician and have him install a GFCI- protected receptacle closer to your pond! Besides the fact that burying wire underground requires special cable and conduit, the amount of distance between your current outlet and your pond will almost certainly ruin your pump due to voltage loss. It will be cheaper (AND SAFER) in the long run if you do it properly and have a receptacle (or even better, a sub panel with several dedicated receptacles) installed closer to your pond. This way you can also have power for a UV light, air pump, lighting, or whatever else you may want to add later on.
By threading the electrical cord through some plastic conduit then laying it into the ground and covering it up. Make sure water can't run into the conduit.
need to use direct burial wire from your source run a #12 direct burial to a weather proof outlet box than plug the fountain into that the ground will over time eat up a extension cord up and it will short out
On the outlet be sure and use a GFCI outlet
