How old is the oldest rock in the Canadian Shield?
4.28 billion years old

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).
Can you burn petrified wood?
Answer and Explanation: Petrified wood will not burn because it is mostly made up of the mineral quartz rather than plant cells like living trees today. This is because petrified wood is simply a mineral cast of a once living tree and therefore has no organic cells anymore.
Where is the oldest petrified wood found?
The oldest is called Callixylon and occurs in the Devonian-age Woodford Shale in the Arbuckle Mountains and near Ada.
