Have there been nuclear tests in Greenland by Canada to find out whether blasts have been able expose lava?

Question

Little has been known whether the contents of the inside of the earth can be exposed by man.

Digging into the earth is a very hard and imposible job so one can dig as deep as possible and then blast the remainder by nuclear. green land is most favored to conduct such experiments as there are no inhabitants.
Has there such event ocurred and if not where on Earth has man been able to dig into the Earth reaching close to the intrior of the Earth?

Answer 1

I think you miss the point in these sorts of experiments. We don't NEED to dig into the ground to see what's there.

Any material has one very special property that can be used to determine what it is without ever seeing it. This is its internal vibration-state modes. Causing a broad-band vibration on one side of the Earth of a certain frequency and detecting it on various points on the other side of the Earth will show you which frequencies of vibration were absorbed and which were not. The positions of the sensors will determine where in the Earth's structure the various vibrations detected came from. Then there is the task of analysing the data (there will be reflections and refractions you must take account of). Finally, a computer model is built based on the structure of the Earth you worked out to see if your structure is right, and the whole experiment is re-run on the computer. If the same results come out, you know the structure.

It was using this technique that led to the discovery that the centre of the Earth is a super-heated SOLID lump of iron which may act as a super-conductor under certain conditions (A LOT of information can be obtained from learning what the allowed vibrational states of the materials are).

NOTE: I am sure the inhabitants of Greenland won't be too happy with you forgetting about them!

Answer 2

researchers in the Soviet Union once had a drilling project(Kola Superdeep Borehole) whose goal was to penetrate the Earth's upper crust and sample the warm, mysterious area where the crust and mantle intermingle– the Mohorovicic discontinuity. So deep is this area that the Russian scientists had to invent new ways of drilling,despite the effort which spanned several decades, the Russians never reached their goal. The work done by the Soviets did, however, provide information about what lies just beneath the surface.

Answer 3

The Russians dug a really, really deep hole one time.
