There are five basic kinds of mountains: dome, fold, fault-block, volcanic, and plateau mountains. These different types of mountain names not only distinguish the physical characteristics of the mountains, but also how they were formed.
Dome Mountains
Dome mountains are the result of a great amount of melted rock pushing its way up under the earth without folding or faulting resulting in a rounded dome. As the dome is raised above its surroundings erosion occurs, and as a result of erosion, peaks and valleys are formed.
Fold Mountains
Fold mountains are formed when two plates collided head on, and their edges crumbled, much the same way as a piece of paper folds when pushed together.
Examples of fold mountains include Himalayas in Asia, the Alps in Europe and the Andes in South America

Fault-block Mountains -
These mountains form when faults or cracks in the earth's crush force some materials or blocks of rock up and others down. Instead of the earth folding over, the earth fractures and blocks are stacked. Examples include the Sierra Nevada mountains in North America and the Harz Mountains in Germany.
Volcanic Mountains
Volcanic Mountains are formed when molten rock, or magma deep within the earth, erupts, and piles upon the surface. Examples of Volcanic Mountains include Mount St. Helens in North America and Mount Pinatubo in the Philippines.

Plateau Mountains (Erosion Mountains)
These are mountains that are really plateaus that have worn down from erosion. The dictionary describes these as large areas of ‘high levels’ of flat land.
Did you know?
Two Tectonic Plates meet along the Southern Alps. This is called a fault line. The Southern Alps are constantly changing because the Pacific Plate is being pushed down under the Australian Plate and that causes the Alps to rise up.
