Question

Answer the following question briefly.
What are the different types of mountains?

Answer 1

Hint: A mountain is a raised part of the Earth's crust with steep sides and exposed bedrock. A mountain is higher than a hill and has a smaller summit area than a plateau, rising at least 300 metres (1000 feet) above the surrounding ground. Just a few mountains have isolated summits, but the majority are found within mountain ranges.

Complete answer:
There are an infinite number of landforms on the planet. The four main types of landforms are mountains, valleys, plateaus, and plains. Any natural elevation of the earth's surface is referred to as a peak. They usually have steep, sloping sides with sharp or rounded ridges, as well as a high point known as a peak or summit. A mountain range is a grouping of mountains that are similar in proximity to one another.

There are three kinds of mountains:
1. Fold mountains: Fold mountains are formed when two or more of the Earth's tectonic plates collide. Rocks and rubble are twisted and folded into rocky outcrops, hills, valleys, and entire mountain ranges as these colliding, compressing borders collide.

2. Block mountains: Fault blocks are very large blocks of rock formed by tectonic and localised stresses in the Earth's crust, often hundreds of kilometres in length. Faults break up large areas of bedrock into blocks. The lithology of blocks is reasonably consistent. The crustal blocks are the largest of these fault blocks. Terranes are large crustal blocks that have broken away from tectonic plates.

3. Volcanic mountains: Molten rock (magma) from deep inside the planet erupts and piles up on the surface, forming volcanic mountains. When magma bursts through the earth's crust, it is known as lava. When the ash and lava cools, it forms a rock cone. Layers of rock and lava build up on top of each other.

Note: Mountains are created by tectonic forces, erosion, and volcanism, all of which operate on time scales of millions of years or longer. Mountains are gradually flattened after mountain building stops, due to weathering, slumping, and other forms of mass waste, as well as erosion by rivers and glaciers.
