It is said that mountains are created from the action of Plate Tectonics. When continents drift toward each other and collide head on, the results are mountains. The Himalayan Mountains, known as the highest mountains in the world, were created when the Indian-Australian plate collided with the Eurasian plate. (Miller, 1983) This occurred around 50 million years ago. The continents density was about the same capacity so one could not collapse under the other therefore the pressure caused upward motion forming the Himalaya mountain peaks. The Andes Mountains near South America seem to be increasing in height possibly due to the ocean floor scraping growing thicker causing an increase at the roots of the Andes making the mountains higher. (White, W. M. (2012) When plates are able to sink under the other plates, deep trenches are formed. One of these examples is the deepest point on earth known as the Mariana trench located in the North Pacific Ocean. (Miller, 1983) This type of action can also cause underwater volcanoes to be formed which can eventually build to create islands such as Japan.
