Which mountains are near an active continental margin?

Mountains that are near an active continental margin are typically formed as a result of tectonic activity associated with plate boundaries. An active continental margin is characterized by a high degree of tectonism, including earthquakes, volcanic activity, and mountain building, and is most commonly found along convergent plate boundaries, where an oceanic plate subducts beneath a continental plate. The mountains formed in this environment are often volcanic in origin or are uplifted as a result of compression and folding. One of the most prominent examples of mountains near an active continental margin is the Andes mountain range in South America, which is associated with the subduction of the Nazca Plate beneath the South American Plate. Other notable examples include the Cascades in the Pacific Northwest of the United States and the Southern Alps in New Zealand.
