Where are the oldest and youngest rock layers found?
The principle of superposition states that the oldest sedimentary rock units are at the bottom, and the youngest are at the top.
Where the oldest and youngest rocks are?
The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first) and rock strata (layers) closest to the ground surface are the youngest (formed most recently).

How do you know which rock is the oldest?
Cross dating is a method of using fossils to determine the relative age of a rock. Fossil remains have been found in rocks of all ages with the simplest of organisms being found in the oldest of rocks. The more basic the organism the older the rock is.
Where did the oldest rocks come from?
What is this? In 2001, geologists found the oldest known rocks on Earth, the Nuvvuagittuq Greenstone Belt, on the coast of the Hudson Bay in northern Quebec. Geologists dated the oldest parts of the rockbed to about 4.28 billion years ago, using ancient volcanic deposits, which they call “faux amphibolite”.
