Complete answer:A mountain is a large landform that rises from the ground, forming a peak, and is formed due to tectonic forces or volcanism. It is usually steeper than a hill and has a colder climate than at sea level because of which there are limited plants and animals. When a series of mountains are connected in a line or series on higher ground it is called a mountain range. Sometimes, these mountain ranges act as natural borders between nations, making them a political border. The highest mountain range on the Earth is the Himalayas, which has an average elevation of 7,200 m and has a length of 2400 m. It is located in Asia and acts as a boundary between the plains of the Indian Subcontinent and the Tibetian Plateau. It also includes the highest mountain on the Earth that is Mount Everest which has an elevation of 8,850 m. The Andes is a mountain range in South America and has a length of 7,000 km and 200 to 700 km wide making it the longest continental mountain range in the world. It has an average height of about 4000m. It runs through seven South American countries: Venezuela, Colombia, Argentina, Peru, Bolivia, Ecuador, and Chile.

Note:The highest mountain on the Earth is Mount Everest which is Nepal and has an elevation of 8,848.86 m above sea level. The tolerable altitude for humans to survive is 5,950 m above which it is a death zone because there is a limited supply of oxygen and less protection against solar radiation.
