Here's a breakdown:

* Forces inside the Earth: These forces, often associated with plate tectonics, exert pressure on the Earth's crust.

* Upward Movement: This pressure causes the crust to buckle and fold upwards, creating a dome-shaped uplift.

* Erosion: Over time, erosion by wind and water sculpts the uplifted area, creating the characteristic features of upwarped mountains.

Examples of upwarped mountains:

* The Black Hills of South Dakota, USA: Formed by a large, dome-shaped uplift.

* The Adirondack Mountains of New York, USA: Created by the upwarping of ancient, Precambrian rocks.

* The Harz Mountains of Germany: Also a result of a dome-shaped uplift.
