The type of mountain that forms when rock layers are squeezed together and pushed upward is called a folded mountain.

Here's a breakdown:

* Folding: This process happens when tectonic plates collide, causing the layers of rock to bend and buckle.

* Upward push: The immense pressure from the colliding plates pushes the folded rock layers upwards, creating mountains.

Some famous examples of folded mountains include:

* The Himalayas

* The Alps

* The Appalachian Mountains
