when acid rain makes it dosolve
and wham sink whole lol

The Appalachian Mountains
The Appalachian Mountains consist of several ranges, including the Blue Ridge Mountains, the Great Smoky Mountains, and the Allegheny Mountains. These ranges form the Cordillera Appalachia in the Eastern United States.
Snow storms in the Appalachian Mountains and the Rocky Mountains form when moist air is forced to rise over the mountains, leading to cooling and condensation of water vapor into snow. The moisture for these storms can come from nearby bodies of water, such as the Atlantic Ocean for the Appalachian Mountains and the Pacific Ocean for the Rocky Mountains.

The Appalachian Mountains are the most prominent land form in eastern North America. Extending from Newfoundland in Canada to Alabama in the United States, the range is known for its diverse ecosystems and rich biodiversity. The Appalachian Mountains have played a significant role in shaping the region's geography and influencing settlement patterns.
The collision of tectonic plates during the formation of the supercontinent Pangaea is the most likely geological event that caused the Appalachian Mountains to form. Approximately 480 million years ago, the collision between the North American and African plates caused the mountains to uplift.
The Appalachian Mountains are 1,500 miles long. They were discovered in June 1528 by Panfilo de Narvaez, when he led an expedition into Apalachee territory.
I think its the Appalachian Mountains.
Sinkholes form when limestone dissolves and pores and cracks grow bigger.
The Appalachian Mountains form a boundary with the Canadian Shield. The Canadian Shield is a large geological formation covering much of eastern and northern Canada, while the Appalachian Mountains run along the eastern coast of North America, from Alabama in the U.S. to Newfoundland in Canada.
Two kinds of mountains are volcanic mountains, which form from volcanic activity, and fold mountains, which form from tectonic plate collisions causing the Earth's crust to fold and create mountain ranges.
