The major moutain belts of the earth with higher mountain ranges tend to be geologically younger then those with lower mountain ranges, due to ersional factors. A mountain range with specific rock strata from a specific geologic time can be dated, this is usually done with the aid certain types of fossils known to that geologic time or by radiometric dating. Some known rocks are much older than others and through this age can be determined. If you have any further questions, feel free to email me

By the amount and type of layers in the rock strata ( cross section ). Quite like growth rings on a tree.
