Answer to Question 1

gravestones?
Measure loss of material on old gravestones. (Know time elapsed from epitaph, estimate original depth of engraving from new gravestones)
Identify areas of erosion or deposition in the yard.

Answer to Question 2

The main difference you would see from an intrusive and extrusive igneous rock formed from the same magma would be in the grain size of the minerals. The extrusive rock would have small crystals, some so small that you cannot see them with the naked eye.

The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
