The largest mountains on continents are formed by deformation

The largest mountains on the continents are formed by stress deformation.

This is also know as strain, which is a process that occurs when the intensity of the stress is greater then the internal strength of the rock. This kind of activity, forming of mountains, occurs when to tectonic continental plates with same densities are colliding, so under the pressure, stress, they create, the area of collision is lifting up.
