Use your own words to describe how the Appalachian Mountains were formed?

The Appalachian Mountains were formed over hundreds of millions of years through a combination of tectonic activity, erosion, and sedimentation. Initially, they arose from the collision of tectonic plates, which caused the land to buckle and fold. Over time, erosion wore down the peaks, shaping the landscape into the rugged mountains we see today. This process involved the gradual uplift and weathering of ancient rock formations, making the Appalachians one of the oldest mountain ranges in North America.
