How old are the rocks on the moons?
since they are not actually rock but very old cheese it is sometimes hard to tell their exact age. Scientists however speculate that they are between 1200 and 1800 years old.

What is stratification and why is it important to earth scientists?

What is the methods that tells you which layer of rock is oldest but does not tell you exactly how old?
Relative dating
Can scientisits find out how old a mountain is without finding a fossil?
== NO a fossil must be found but scientists can probably guess about how old the mountain is by looking at it and fing== ding out the types of rock that it has. ===
How do scientists find the absolute age of fossils and rock correlations?
Well if it was deep in the ground it was probably old.
What two things did 19th century scientists do to determine the relative ages of sedimentary rock all over the world?
They studied fossils and applied the principle that old layers of rock are below young layers! -
