The Andes, Rocky, and Appalachian Mountains are significant mountain ranges with unique formations and characteristics, spanning regions in both North and South America.
The Andes Mountains are considered the world's longest mountain range, stretching over 4,500 miles and featuring more than 30 peaks exceeding 20,000 feet in elevation, many of which are active volcanoes. This mountain chain extends along the western region of South America, from Venezuela to southern Chile, dominating the continent's physical geography.
The Rocky Mountains run from New Mexico to Northern Canada, formed mainly during the Late Paleozoic and the Laramide Orogeny. Unlike the Himalayas, the Rockies were shaped by low-angle subduction and are no longer actively growing. They have been eroded and glaciated over time, rounding their highest peaks.
The Appalachian Mountains are the remnants of a larger mountain range, shaped by continent-continent collisions during the time of Pangaea. This range, much older than the Rockies, runs from New England to northern Alabama, with the highest peaks reaching just above 6,600 feet and characterized by steep, forested terrain with orderly ridges and valleys.
