First: geologists look at the general shape of the mountain: Sharper peaked mountains are generally younger than rounded ones because erosion has had less time to wear them down (ie the Rockies are younger than the Appalachians).
Second: geologists look at what type of rock is exposed. Not only does this tell us something about when the formation began, it also gives us something to base our erosion estimation off of. Sandstone erodes faster than granite, so you could have a rounded mountain peak made of sandstone that was the same age as a sharp granite peak.
Third: geologists will consult with paleontologists and archaeologists to try to determine the age of the mountain based off of remains that may be present on the mountain. (If, for instance, we find fossil sea-shells, we know that the mountain formation has to fall within certain ranges).
Geologists. They study solid Earth, the rocks of which it is composed, and the processes by which they change.
Fossils help geologists discover new species. Fossils also explain and show the age of the specimen and change in life forms.
geologists believe the force may be caused by the collision of lithospheric plates.......

The material on the mountains was not always up there. Mountains are generally created by what is called uplift. And places that were under water and then had remains laid down and fossilized can be uplifted through long periods of time to create mountains. The fossils are then found up there in the mountains. The geologic process is fairly well understood and modeled by geologists.

Geologists have trouble explaining how fold and fault-block mountains came into being.

explain why some rock formations that are commonly called mountains are not really considered to be mountains by gealogist
The Himilayas are relatively young geographically speaking. Geologists estimate Everest's age to be 50-60 million years old.

Several things are studied by Earth scientists who specialize in tectonics. Plate boundaries, plate tectonics, boundaries, continental drift, mountains, and volcanoes are all studied.
Geologists determine absolute age of rocks by using radioactive dating.
Fossils help geologists discover new species. Fossils also explain and show the age of the specimen and change in life forms.
