Building a Mountain

FOLD Mountain

Fold mountains are formed when layers of tectonic plates fold onto each other because of large amounts of sediment. These mostly occur at convergent boundaries which contain continental plates, and are going to create a subduction zone which will transfer sediment from a oceanic plate all the way to each plate. The continental plates are becoming folded after this, which is why the name "FOLD," affects these mountains.

The Himalayan Mountain range wold be a great example of fold mountains.


BLOCK Mountain

This happens when a fault block is either raised or tilted, which creates the 'BLOCK' mountains. The higher parts of the mountain are called the Horst, and the lower trough-like parts are called the Graben. When they spread apart they cause strong tensional forces which cause the Graben to form.

The Hanging Hills of Connecticut would be a sufficient example of a Block mountain range:


Volcanic Mountain are formed in many different ways, but mostly start as convergent boundaries pushing the crust up and causing the magma to add up. The magma then goes to the surface of the Earth and begin to cool, which forms rock. The running lava creates a gently sloped mountain which would be classified as a shield mountain. Then the combinations of ash and smoke create a cinder mountain.
