How do mountains form?

Answer 1

The main process by which mountains form is through tectonic activity. When two tectonic plates collide, the crust is crumpled and pushed upwards to form mountains (as an analogy, imagine the effect of pushing a rug up against the wall). Of course, this is a slow process that happens over millions of years, which is why you don't notice any mountain building going on today. Mountains can also be formed by the buildup of igneous rock from volcanoes.

Volcanic mountains are formed either through the introduction and accumulation of magma over a crustal "hot spot" or through volcanic activity associated with the collision and subduction of a crustal plate, where the melting of the subducted crust creates magma, gases and pressures that are released in eruptions.

Continental crustal plate collisions, where neither plate subducts, create mountain ranges such as The Himalayan Mountain Range, where crustal material is thrust upward faster than erosion can wear it down.

Plates can stretch until they crack and slide, forming fault-block mountains.

In the ocean, great underwater mountains are formed when plates spread away from one another, and melted rock pushes up through the gap, creating hot, buoyant elevations of new crust (a simplification of the process).

this is how do mlountains form

Answer 2

When hot rock form within the earth rises through the ocean flood as plates separate. This forms a volcanic mountain chain or ridge, on the ocean flood.
