Mountains are formed through various geological processes, such as tectonic activity, volcanic activity, and erosion. Tectonic forces can cause the Earth's crust to fold, creating fold mountains, or to rupture and form fault-block mountains.
Mountains are large landforms that rise prominently above the surrounding terrain. They are characterized by their steep slopes, high elevations, and often rocky or rugged landscapes.
The highest mountain in the world is Mount Everest. It is located in the Himalayas and lies on the border between Nepal and Tibet (China). Mount Everest has an elevation of 8,848.86 meters (29,031.7 feet) above sea level, according to a 2020 survey conducted by China and Nepal.
