An orogeny is a mountain forming event that results in the formation of a mountain range. The basic steps of an orogeny are a continental plate colliding with an oceanic plate and causing uplift in the landscape. Eventually, after thousands of years, the continental plate begins to collide with another continental plate and the uplift becomes a little bit more drastic. This process continues for thousands of years and in some cases is still continuing, but this tectonic activity which is in line with the theory of plate tectonics is what causes mountains to form. There are some famous mountains out there but each continent has its own range, tallest mountain, and orogeny to claim. Highest Mountain in Asia: Mount Everest. Its summit is 29, 035 ft. above sea level and it is located near the border of Nepal and China. It formed 60 million years ago when the Indian plate collided with what is now the Asia plate. Highest Mountain in North America: Mount McKinley. Its summit is 20, 320 feet above sea level. It is located in the Unites States in the state of Alaska. If dates back 60 million years also. Highest Mountain in South America: Mount Aconcagua. Its summit is 22, 834 feet above sea level. It is located in Argentina. Its formation dates back to Precambrian times. Highest Mountain in Australia: Mount Kosciuszcko. Its summit is 7, 310 feet above sea level. It is located in New South Wales. Highest Mountain in Antarctica: Vinson Massif. Its summit is 16, 066 feet above sea level. Highest Mountain in Europe: Mount Elbrus. Its summit is 18, 510 feet above sea level. It is located in Russia. Highest Mountain in Africa: Mount Kilimanjaro. Its summit is 19, 340 feet above sea level and it is located in Tanzania. Each of these mountains are continually growing and are continually being worn away by the elements.
