A mountain is an elevated land usually higher than its surroundings. Some are by themselves, but they usually are in ranges. Some mountains can be remains of plateaus. Others are cones of volcanoes formed with igneous rock. Most of the great mountains are either fold mountains or complex structures formed by many different natural activities. Although, the plate tectonics is the first reasonable theory, stating that the crust of the earth breaks into several parts that eventually collide with another. Where they collide, they bend and fold the land upward, which forms folded or faulted mountain ranges. The highest point on earth, Mt. Everest, is also believed to have been formed by folding when the Australian-Indian plate collided with the Eurasian plate. Mountains can be created in many different ways. The two best-known and quite common ones are volcanic mountains and folded mountains.Other important ones include left over mountain formation in which a plateau is eroded away into a mountain.1. Folding & FaultingThe earth is changing its shape constantly every year by a few centimeters. This causes the earth to move from one huge continent called Pangea to what it looks like now in almost 200 million years. When the giant pieces of land move around, they tend to bump into each other. When they collide, they create a fold, and if the fold gets too much pressure, it breaks and becomes a fault. Fold and Fault mountains are everywhere throughout the world.2. Left Over MountainsDue to the weathering, parts of the world change frequently, but slowly. This can also happen to a plateau. If a small plateau’s edges are washed away by rain and wind, it forms a new mountain-like structure, which we call residual (left-over) mountain, meaning that it became a mountain from the remainders of many types of erosion. 3. VolcanoesVolcanoes are formed when the magma reservoir underground erupts. Also there are many different types of erupti...
