Where can we find the oldest rocks?
The Nuvvuagittuq Belt on the coast of the Hudson Bay in Northern Quebec. Scientists have found the oldest known rocks on Earth. They are 4.28 billion years old, making them 250 million years more ancient than any previously discovered rocks.

What is rock system?
A system in stratigraphy is a unit of rock layers that were laid down together within the same corresponding geological period. … Systems are unrelated to lithostratigraphy, which subdivides rock layers on their lithology.
How can you tell a rocks age?
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.
Which is the oldest rock in the world?

What is the oldest material on Earth?
Scientists analysing a meteorite have discovered the oldest material known to exist on Earth. They found dust grains within the space rock – which fell to Earth in the 1960s – that are as much as 7.5 billion years old.
How old are the youngest rocks in the Grand Canyon?
270 million yearsRemember, the oldest rocks in Grand Canyon are 1.8 billion years old. The canyon is much younger than the rocks through which it winds. Even the youngest rock layer, the Kaibab Formation, is 270 million years old, many years older than the canyon itself. Geologists call the process of canyon formation downcutting.
