what type of mountain formation is the andes?
531084
The Andes were formed by tectonic activity whereby Earth is uplifted as one plate (oceanic crust) subducts under another plate (continental crust). To get such a high mountain chain in a subduction zone setting is unusual, which adds to the importance of trying to figure out when and how it happened.

What are the three most common types of mountain? Give a brief description and an example of each. The three most common types of mountains are fault-block, folded, and volcanic mountains. Fault-block mountains occur at divergent boundaries.

Formation & Structure of the Rwenzori Mountains This range is estimated to have formed 3 million years ago. While they are not volcanic, these mountains are a result of uplifted blocks of crystalline rocks such as gneiss, quartzite, amphibolite, and granite.

Mount Fuji, Japan, is one of the most famous mountains in the world. Mount Fuji is a composite cone, or stratovolcano. Composite cones, formed by violent eruptions, have layers of rock, ash, and lava.

Why are the Andes Mountains often studied? The Andes contain the most extreme variations in landscape, vegetation and climate of any mountain group in the world. ... Main roads on the mountain and coast side were linked by connecting roads.

Mountains are made from geological processes, such as erosion (wearing away at the surface), volcanic eruptions, and movement of tectonic plates. ... Upwarped mountains form from pressure under the earth's crust pushing upward into a peak. Volcanic mountains are formed from eruptions of hot magma from the earth's core.

Mountains, hills, plateaus, and plains are the four major types of landforms. Minor landforms include buttes, canyons, valleys, and basins.

A mountain results from various geological processes such as movement and opposition of tectonic plates. On the other hand, a volcano forms around a vent when magma flows out and reaches the surface of the earth.

Dome mountains are formed when a large amount of magma builds up below the Earth's surface. This forces the rock above the magma to bulge out, forming a mountain.

The Andean Volcanic Belt is a major volcanic belt along the Andean cordillera in Argentina, Bolivia, Chile, Colombia, Ecuador, and Peru. It is formed as a result of subduction of the Nazca Plate and Antarctic Plate underneath the South American Plate.

Volcanic Mountains are formed when molten rock (magma) deep within the earth, erupts, and piles upon the surface. Magna is called lava when it breaks through the earth's crust. When the ash and lava cools, it builds a cone of rock.

The Cascade Mountain Range is a line of volcanoes above the melting oceanic plate. The Andes Mountain Range of western South America is another example of a convergent boundary between an oceanic and continental plate. Here the Nazca Plate is subducting beneath the South American plate.

Collisional mountain ranges form when two continental plates converge at a continental-continental convergence zone.

The Andes mountains were formed as a result of a convergence of plate tectonics. The Nazca Plate moved eastwards, towards the South American Plate finally colliding and forming the Andes about 45 million years ago.

Fold mountains are the most common type of mountain in the world. The rugged, soaring heights of the Himalayas, Andes, and Alps are all active fold mountains. The Himalayas stretch through the borders of China, Bhutan, Nepal, India, and Pakistan.

The Appalachian Mountains, often called the Appalachians, are a system of mountains in eastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period.

Fold mountains are created where two or more of Earth's tectonic plates are pushed together. At these colliding, compressing boundaries, rocks and debris are warped and folded into rocky outcrops, hills, mountains, and entire mountain ranges. Fold mountains are created through a process called orogeny.
