The type of mountain formed by upward movements of Earth's crust is called a fold mountain.

Here's why:

* Upward Movement: Fold mountains form when tectonic plates collide, causing the Earth's crust to buckle and fold upwards.

* Folding: The immense pressure of the colliding plates forces the rock layers to bend and fold, creating the characteristic peaks and valleys of fold mountains.

* Examples: Some famous examples of fold mountains include the Himalayas, the Alps, and the Andes.
