Earthquakes. Usually small and unnoticeable ones.
Well, actually , its the cracks in the ground that the earthquakes make, then if they accidentaly hit each other, they will form a mountain.
Take the question somewhat seriously please. If you are interested in plate tectonics you know that the continents and sub-ocean plates are in motion. These can cause earthquakes, but that does not cause the mountain to form, just a symptom. For instance the Indian sub-continent is pushing northward into Asia and meeting resistance. The result is uplift and the Himalayan Mountains are formed and still growing. Some mountains are formed when volcanic activity develops as in the Hawaiian Islands.
* The Appalachian Mountain Range * Rocky Mountain Range
Where is North Mountain? wrong answer idiot
The Appalachian Mountain chain.
Rocky Mountain
The tallest mountain in the US is Mount McKinley at 20,320ft
rickettsia
stromboli mountains
After sunset the sun is no longer warming the mountain side and there is cooling of the air along the slope. The air becomes more dense and sinks into to valley. Thus the wind blows from the mountain side down into the valley and is thus called a mountain breeze.
Anticlines and Synclines typically form during crustal deformation as the result of compression that accompanies orogenic mountain building.

Orogeny.
IT WAS CAUSED by pollution.
Lava may form a mountain called a volcano!
It takes 20 years for a folded mountain to form
Mountain breezes form during night.
