Volcanic Mountain Ranges:
* Andes Mountains (South America): Formed by the subduction of the Nazca Plate beneath the South American Plate. The resulting volcanism created numerous volcanoes and the iconic peaks of the Andes.
* Cascade Range (North America): This range is formed by the subduction of the Juan de Fuca Plate beneath the North American Plate. It features notable volcanoes like Mt. Rainier, Mt. Hood, and Mt. Shasta.
* Rocky Mountains (North America): Although the Rockies are primarily formed by sedimentary rocks, they contain extensive areas of igneous rocks. These rocks are often found in the cores of the mountains and were formed by volcanic activity during the Laramide Orogeny.
* Sierra Nevada Mountains (North America): These mountains are primarily composed of granite, a type of igneous rock that was formed by the cooling and solidification of magma beneath the Earth's surface.
* Himalayan Mountains (Asia): While the Himalayas are mainly formed by tectonic uplift of sedimentary rocks, they contain several igneous rocks associated with volcanic activity in the region.
Other Igneous Mountain Ranges:
* Adirondack Mountains (North America): These mountains are composed of igneous rocks formed during the Grenville Orogeny, a period of mountain building that occurred about a billion years ago.
* Black Hills (North America): These mountains are formed by a granite intrusion, a large body of igneous rock that has been pushed up from below the Earth's surface.
Remember that while igneous rock is a primary component of these mountain ranges, other types of rocks like sedimentary and metamorphic rocks can also be found. The specific composition varies greatly depending on the specific mountain range and its geological history.
