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.

The correct order of levels of organization in a complex organism is: cell, tissue, organ, organ system, organism..cells --> tissues --> organs --> organ systems --> organism.

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
