The Appalachian Mountains, which appear in the image, formed during the Silurian period. This time before the Devonian began 443 million years ago, and ended 416 million years ago. This is the third period of the Paleozoic, and at this time the level of the oceans was high. The continents were still moving, and although slow, the face of the Earth had already changed a lot.
Europe and America were approaching, the surface seas closed and mountains formed, such as the Caledonias, the Scandinavian mountains or the Appalachians. The latter gave rise to an important mountain range in eastern North America. They cover from Newfoundland and Labrador, in Canada, to Alabama, in the United States. Its northernmost zone ends on the Gaspé Peninsula, in Quebec, Canada.
These ancient mountains have reliefs very softened by the prolonged action of exogenous agents. The average height of its peaks is around 1,000 meters above sea level. The highest peak is Mount Mitchell, in North Carolina, which measures 2,037 meters.
The geology of the Appalachians is very peculiar and interesting, since its formation originated from one of the first collisions that occurred in the history of the Earth between cortical plates. That is why this whole area is very stable tectonically because, being a very old sector, no contact seizures between plates no longer occur.
