Texture
The spectral lines. Each element has a characteristic "fingerprint" in a spectrum.
The details are quite complicated, but as I understand it, the main evidence is radioactive decay. The exact mix of isotopes of different elements in a compound can provide evidence of how old it is (sometimes this might mean, when a substance solidified), since the mix of isotopes will change over time, in case some of the isotopes are radioactive.

No, they are different heights. Visit Uxbridge for the evidence.
They go underground and see what there if it is deep they can use a submarine
