Why Is Mount Everest Considered the Tallest Mountain?

Mount Everest is considered the tallest mountain in the world because it has the highest elevation above sea level, peaking at 8,848.86 meters (29,031.7 feet). This measurement makes it the tallest when elevation is the criterion used for comparison.

According to the National Geographic Society, Mount Everest’s height has been confirmed through various surveys and measurements conducted in collaboration with the Chinese Academy of Sciences and other organizations. Their precise measurements highlight Mount Everest’s status within geographical studies.

The designation of Mount Everest as the tallest mountain is primarily due to its geological formation and location. Mount Everest is part of the Himalayas, formed as a result of tectonic activity. The Indian tectonic plate collided with the Eurasian plate millions of years ago, causing buckling and folding of the Earth’s crust. This collision formed high mountain ranges, including the Himalayas, where Mount Everest is situated.

In geological terms, “elevation” refers to the height of a location on Earth’s surface above a reference point, typically sea level. The measurement of elevation does not take into account the height of the mountain from its base, which may lie below sea level, as with other mountains such as Mauna Kea in Hawaii. Mauna Kea, when measured from its base on the ocean floor, is taller than Everest.

Various processes contribute to the towering height of Mount Everest. Erosion shapes the mountain’s peak, while ongoing tectonic activity continues to push it higher. The combination of these natural forces results in favorable conditions for the mountain’s continual growth.

Specific conditions that influence the height of Mount Everest include tectonic plate movement and erosion rates. For instance, the Nepalese and Indian plates are still shifting, gradually increasing Everest’s height. Meanwhile, erosion from winds and weather conditions shapes its summit. This interplay ensures that Mount Everest remains the highest point on Earth, solidifying its status as the tallest mountain globally.
