Formation of Mountains: Types, Mt Everest Formation & FAQ

In this article, we will discuss the formation of mountains.

  1. Mountains  

Mountains are land’s physical features protruding high beyond the hills and very high up the land surface with steep tops commonly shaped up to a peak. It is a feature that towers or rises above the level of the surrounding area more or less abruptly.

Mountain formation results from the forces of erosion, volcanism, or uplifts in the earth‘s crust. Usually, mountains occur in chains or ranges.
Have complex structures due to folding, faulting, volcanic activity, igneous intrusions, etc.

  2.  Formation of Mountains  

The formation of mountains is done by the folding, faulting, or warping of the Earth’s surface due to the displacement of various plate tectonics or by the formation of volcanic rock onto the surface.

The formation of mountains can be by volcanoes spewing lava over and over again. The lava cools and gets solid and makes a mountain. The islands of Hawaii are made of volcanoes. The formation of mountains takes a million billion years.

  3. Types of Mountain  

Any landmass that is elevated above 1,000 feet in the surrounding area is taken as a mountain.

Different types of mountains have different methods of origin:
a. Fold mountains
b. Block mountains
c. Volcanic mountains and
d. Residual mountain

a. Fold Mountains
i. It results from the earth‘s crust being compressed from the sides
ii. The layers of rocks in the crust are pushed up to form a fold mountain.
iii. The Alps, Himalayas, and the Andes are examples.

b. Block Mountain
Mountains formed due to faulting.
i. A part of the land block is depressed so that the remaining block stands conspicuously above the
surroundings.
ii. The uplifted section is termed the block mountain (horst)
iii. When the middle section falls down instead of going up, it forms the rift valley (graben).

c. Volcanic Mountain
i. The outrushing magma forms the fissures in the crust of the earth at a place into a dome, mountains formed in such a way are called volcanic or laccolith mountains.
ii. Volcanoes emit gases, liquids, and solids as well. The gases are lost in the atmosphere, but the liquid and solid accumulate and heaps around the fissure or orifice.
iii. During continued activity for years, the accumulation grows into an enormous size justifying the name mountain.

d. Residual Mountain
i. When existing mountains or plateaus are in eroding state the resulting structures are called
residual mountains or relict mountains
ii. The eroding agents are snow, wind, rain
iii. They erode the softer materials from the existing mountains thus reshaping the lower hills and valleys.

  4. How was Mt Everest formed?  

Mount Everest was produced from a tectonic collision between the Indian and Eurasian tectonic plates tens of millions of years ago. The smashup crushed the landscape, elevating mountains along 1,5000 miles, a range that is known as the Himalayas range.

  5. Which rock is found on Mt Everest?  

The common rocks and minerals available on Mount Everest are granite, limestone, garnet, and schist. Granite is an igneous rock available on the lower slopes of Mount Everest and entire the Everest region.

  6. Did Mt Everest grow after the earthquake?  

Mt Everest has grown by 86 cm but not by the earthquake that came in 2015. The reason behind it is plate tectonics between Indian and Eurasian tectonic plates.

  7. Is Mt Everest a volcano?  

No, Mt Everest isn’t a volcano. It was produced from a tectonic collision between the Indian and Eurasian tectonic plates tens of millions of years ago. The smashup crushed the landscape, elevating mountains along 1,5000 miles, a range that is known as the Himalayas range.

  8. Effect of Earthquake on Mountain  

Larger earthquakes can be the reason behind the formation of mountains topography by making rock uplift more than 1,000 feet but also crumble mountains by causing landslides.

The formation of mountains can be by volcanoes spewing lava over and over again. The lava cools and gets solid and makes a mountain. The islands of Hawaii are made of volcanoes.
