Here's why:

* Anticlines: Anticlines are upward folds in rock layers. Imagine pushing down on a rug - the material would fold upwards.

* Folded Mountains: These mountains are created when tectonic plates collide, causing the Earth's crust to buckle and fold. Anticlines are a key feature of this folding process.

Examples of folded mountains formed by anticlines:

* The Alps: The majestic Alps in Europe are a prime example of folded mountains formed by anticlines.

* The Himalayas: The world's highest mountain range, the Himalayas, is also a result of folding due to the collision of the Indian and Eurasian tectonic plates.

* The Appalachian Mountains: While older and eroded, the Appalachians in North America also exhibit evidence of folding due to ancient tectonic activity.
