Answer:
They can be dated using radioactive carbon. But for rocks older than 50 thousand years they look for layers of igneous rock or volcanic ash above and Bellow the layer of rock/fossil.

Answer:
16L
Explanation:
Data obtained from the question include:
V1 (initial volume) = 4L
P1 (initial pressure) = 4atm
P2 (final pressure) = 1atm
V2 (final volume) =?
Using Boyle's law equation P1V1 = P2V2, the new volume can be obtain as follow:
P1V1 = P2V2
4 x 4 = 1 x V2
16 = V2
V2 = 16L
Therefore, her new lungs volume is 16L
