Mountain Building
How are mountains formed?
Mountain Formations
Mountains form in many different amazing ways. There are three different main processes that mountains can go through to be formed. Each different way creates it's own unique and brilliant mountain.
The Processes
Fold Moutains
Fold mountains are most commonly found and were formed over millions of years. The worlds largest mountain ranges are fold mountains. Fold mountains are formed when two plates collide head on and their edges crumble. Upward folds in these mountains are called anticlines, while downward folds are called synclines.
Volcanic Moutains
Volcanic mountains form when magma erupts from deep within the earth and piles on the surface of the earth. When this ash and lava on the crust cools it builds a cone of rock. This process repeats and layers pile on top on one another, building the mountain. The layers that have cooled become rock, so when more lava cools on top of it, it makes another layer. This is how the mountain forms and gets bigger.
Fault Block Moutains
Fold mountains form when faults or cracks in the earths crust force some materials, blocks of rock, up and others down. The earth's crust fractures and breaks into blocks or chunks of rock. These blocks can move up and down as they move apart. Blocks of rock end up getting stacked on one another because of this.
Examples
The Urals
The Urals are located in Russia, they are an example of fold mountains.
Mount Pinatubo
Mount Pinatubo is located in the Philippines, it is an example of a volcanic mountain.
Harz Mountains
The Harz mountains are located in Germany, it is an example of fault block mountains.
