What Is The Reason Behind Mount Everest’s Height

Mount Everest, which is also known by the name Qomolangma is the highest mountain on the planet. The mountain’s top peak lies a staggering 8,850 meters above sea level.

Mount Everest has become an adventure point for climbers:


Every year, hundreds of people wait for the chance to climb the world’s highest mountain.

They wait for the perfect weather conditions


The mountain can only be climbed when weather conditions are very specific. People wait for ages at the base camp for the weather to get good enough to allow climbing.

Mount Everest is not the tallest, but has the highest altitude


Mauna Kea has a total height of 10200 meter from base to top, and is taller than Mount Everest. However, Mount Everest has the maximum altitude above sea level, and therefore is the highest mountain on the planet.

Why is Mount Everest so high?

To understand, we have to first understand more deeply about the Earth’s crust, which is the Earth’s outer most layer.



The Earth’s crust is made up of huge sized plates. These plates move regularly and so they can go over or under each other.

Rate at which the plates move:


They move at a rate of 2-4 cm a year.

What happens when these plates collide?

When they collide, one plate moves underneath the other while they push into each other. In this way, ridges or up rifts are formed at the margin of the two plates.

3How was Everest formed?


The events happened 50 million years ago. During its movement, Indian plate collided with the Eurasian one, which was much larger. The crust between the two plates formed large up rifts because of the collision. As a result, Mount Everest was formed.

The mountain was shaped by many factors:


When wind was forced to rise as it struck Everest, it cooled down, causing water vapors to condense and form snow and rain. This continuous snow then dissolved the rocks and the landscape. These rocks were carried down by rainwater, resulting in the landscape becoming peaked and jagged.

Effect of time:

With time, the erosion due to rain and snow increased and further changed the shape of the mountain, creating steep valleys and sharp peaks.



Glaciers can erode the rocks underneath very quickly. Mount Everest is so tall because its glaciers are relatively smaller and therefore cannot erode the rocks too much.

Because of melting glaciers and erosion, one day Mount Everest may also decrease in size.
