Answer:
There are three main types of mountains: fold mountains, fault-block mountains, and volcanic mountains.
Explanation:
Fold mountains - Fold mountains are formed when two plates run into each other or collide. The force of the two plates running into each other causes the Earth's crust to crumple and fold. Many of the world's great mountain ranges are fold mountains including the Andes, Himalayas, and the Rockies.
Fault-block mountains - Fault-block mountains are formed along faults where some large blocks of rock are forced upwards while others are forced down. The higher area is sometimes called a "horst" and the lower a "graben" (see the picture below). The Sierra Nevada Mountains in the western United States are fault-block mountains.
Volcanic mountains - Mountains that are caused by volcanic activity are called volcanic mountains. There are two main types of volcanic mountains: volcanoes and dome mountains. Volcanoes are formed when magma erupts all the way to the surface of the Earth. The magma will harden on the Earth's surface, forming a mountain. 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. Examples of volcanic mountains include Mount Fuji in Japan and Mount Mauna Loa in Hawaii.
