Question

states that for undisturbed rocks, the oldest rocks are on the bottom and the rocks become younger and younger toward the top

Answer 1

Yes, rocks get younger the further to the surface you go. This is because of the newer rocks being laid upon the ground last. They can also stick together making sedimentary rock.

Answer 2

True,
because when new rocks are formed they do not start from underground, they start from the materials needed above ground.
