They form by plates pushing upwards

Most of the highest mountains on Earth are formed through the collision of tectonic plates, where one plate is pushed up and over the other, creating large folds and uplifts in the Earth's crust. The immense forces generated by these collisions cause the crust to thicken and push upward, creating mountain ranges like the Himalayas and the Andes.
The highest mountains on Earth, like the Himalayas and the Andes, formed through the collision of tectonic plates. When two plates collide, the crust is pushed upward, leading to the formation of mountain ranges. Over millions of years, the forces of erosion and weathering have shaped these mountains into their current majestic forms.
Most of the highest mountains are formed by the collision of tectonic plates, where one plate is forced under another in a process called subduction. This action pushes up the Earth's crust, creating mountain ranges such as the Himalayas and the Andes. Erosion and weathering also play a role in shaping these mountains over time.
Not all volcanoes are mountains though most do form mountains. Some volcanoes form as simple fissures in the ground. There is a so-called supervolcano in Yellowstone that, does not take the form of a mountain. Kimberlite volcanoes also erupt too violently to form mountains.
Most of the world's mountains form at tectonic plate boundaries, where the movement of the Earth's crust results in the uplifting of land. This can occur at convergent boundaries, where plates collide, or at divergent boundaries, where plates separate. Another common location for mountain formation is at hotspots, where magma from the mantle pushes through the crust.
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.
