what are mountains formed by blocks of crust moving along a fault
Fault-block mountains.
Mountains made of crumpled and folded layers of rock are called fold mountains. The breaking down of materials of Earth's crust into smaller pieces is weathering.
A fault-block mountain is formed by blocks of the Earth's crust moving along a fault.
when 2 plates move away from each other
Features such as mountain ranges, volcanic arcs, and earthquakes are commonly formed along tectonic plate boundaries on continents. These boundaries can result in the uplift of land, the formation of volcanic mountains, and the release of seismic energy. Additionally, continental plate boundaries may also create deep oceanic trenches and transform faults.

mountains usually occur in narrow bands along the edges of continents
The distribution of mountain ranges across different continents, such as the Appalachian Mountains in North America and the Caledonian Mountains in Europe, supports Wegener's idea of continental drift. These mountain ranges were once connected when the continents were part of a supercontinent, and their alignment provides evidence for the movement of land masses over time. Additionally, the presence of similar geological features and rock formations on separate continents suggests a shared history of mountain building.
Fault Block mountains or Horst- formed when colliding plates build up pressure along parallel cracks (faults) in the Earth's surface. The extreme pressure causes large blocks of land to slip and be uplifted. Elevations are normally greater than 3000 meters above sea level. Example: The Sierra Nevadas of California.
mountains or earthquakes
The Andes Mountains running along the western edge of South America were formed by collisions between the South American plate and the
Pangaea, the supercontinent, was formed during the late Paleozoic Era, specifically in the Permian Period. It existed approximately 300 million years ago.
The Tetons are fault-block mountains. This means that they were pushed up as the earth split along a north-south fault line. As pressures deep within the mantle forced the blocks on each side of the crack together, the western block rose to form the mountains and the eastern block sank to form the valley.
