Here's a breakdown:
* Tectonic Plates: The Earth's crust is made up of large plates that move and interact.
* Collision: The Pacific Plate (where Alaska sits) is colliding with the North American Plate. This collision is pushing the land upwards.
* Faulting: The collision creates faults, which are breaks in the Earth's crust. As the plates move, these faults create blocks of rock that shift and rise.
* Uplift: The combined effect of the collision and faulting leads to a general uplift of the landmass, including the area where Denali stands.
Denali is situated near the heart of the Alaska Range, which is a mountain range formed due to this ongoing tectonic uplift. It's the highest mountain in North America, and its height continues to increase slowly but surely because of this geological process.
