Take a walk from Porthmadog, Wales to London. You will pass, in order:
Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian,
Triassic, Jurassic Cretaceous and Tertiary layers. The reason you can
do this is because they are all stacked one on top of the other and
you are walking though the exposed areas.

Grand Canyon: Vishnu Schist and Zoroaster Granite (Pre-Cambrian
Period), Tapeats Sandstone and Bright Angel Shale (Cambrian
Period), Mauv Limestone (Ordovician Period), Temple Bute Limestone
(Dovonian Period), Redwall Limestone (Mississippian Period), the
Supai Group (Pennsylvanian Period), and Hermit Shale, Coconino
Sandstone, the Toroweap Formation, and Kaibab Limestone (Permian
Period).

so you, at least, apparently think the layers are recognized by the
type of material of which they are made. There are those on here who
have said that this is not the case. Who should I believe?


Try reading for comprehension:
" The reason you can do this is because they are all stacked one on
top of the other"
does not mean
"the layers are recognized by the type of material of which they are
made"

How can you possibly extract your interpretation from the statement?
