How is the height of a mountain measured?
The height of a mountain is typically measured from sea level to its highest peak. Sea level serves as the base reference point where the ocean meets the land. From this starting point, surveyors calculate how far a summit extends into the atmosphere. Mount Everest stands as the highest point on Earth because its peak reaches further toward space than any other mountain on the planet.
While some mountains may have a larger physical base or extend deep below the ocean surface, the standard for the world's tallest peak is based on elevation above the sea. This measurement places the summit of Everest at the top of the global list, followed by other massive peaks in the same mountain range.
What are the other highest mountains on Earth?
The second highest mountain in the world is K2, which is part of the Karakoram range. It is known for its steep, triangular shape and sits at an elevation of 28,251 feet. Following K2 is Kanchenjunga, the third tallest peak in the world. These mountains are so high that their summits often sit above the cloud line, creating a distinct environment far above the surrounding landscape.
These three peaks represent the highest points of elevation on the globe. Each one is a massive geological structure that towers over the surrounding terrain. While Everest holds the record for the absolute highest elevation, K2 and Kanchenjunga are also significant for their extreme heights and the way they dominate the high-altitude regions of Asia.
