Fold is the most common type of mountain. Examples of fold mountains include the Himalayan mountains and the Alps. These mountain ranges were formed in the last 10 million years.  The Alps specifically, were formed by the collision of the Eurasian and African continental plates and were then deformed and faulted by thrusting. The Himalayan mountains are the home of Mount Everest whose summit rises to 29,035 feet.  It is the highest point on Earth. 

Fault-block mountains are formed at faults or cracks in the earth's surface that bring deep crustal rocks to the surface. An example of fault mountain ranges are the Sierra Nevada mountain range in California and Nevada, the Tetons in Wyoming, and the Harz Mountains in Germany. 

Dome mountains are formed when magma pushes up on the earth's crust, without erupting.  Dome mountains are individual instances that are isolated structure, they tend to occur in areas of essentially flat-lying sedimentary rocks. There are two types of dome mountains.  They are the plutonic dome, and the tectonic dome mountain.  Examples of the plutonic dome mountains can be found on the border of the Colorado Plateau and the Rocky Mountains. While examples of the tectonic dome mountains are the Adirondack Mountains of New York State and the Black Hills of South Dakota. 

Volcanic mountains are formed when magma breaks through the earth's surface, erupting creating piles on the earth’s surface. An example of volcanic mountains is Mount St. Helens which is found in Washington State – however, the 1980 eruption blew the top off of Mount St. Helens causing the break down of the mountain.  Mt. Fuji located in Japan is another example of a volcanic mountain.  Another great example of volcanic mountains are the islands of Hawaii.  They were formed by undersea volcanoes creating the islands that are seen today.  These islands are the volcano tops.  Hawaii is also home to the World’s tallest mountain.   Mauna Kea, an inactive volcano, when measured from the top to its base, stands 33,474 feet tall, although it only rises 13,796 feet above sea level. 

Plateau mountains are formed by erosion. This is the only mountain type that is formed and effected by exterior forces not internal changes to the earth’s surface. An example of this is the Plateau of Tibet in southwest China.
