The release of magma along the Great Rift Valley began volcanic eruptions between 2 and 3 million years ago. The three separate summits of Kilimanjaro represent the overlapping releases that formed the mountain. Two of the peaks are considered extinct, and the third has been dormant for about 360,000 years.
The uplifted part forms a mountain, and the lowered parts are filled in with eroded material. An example of this is the Sierra Nevada mountain range in California. Another way that mountains are formed is when magma from beneath the Earthâs surface is pushed up, but doesnât actually crack through.This bulge of magma eventually cools and hardens into hard rock, like granite. The layers of softer rock above the magma erode away and youâre left with a large dome-shaped mountain.he mountain ranges are created because of those crumpling plates. The Indian subcontinent âcrashedâ into Asia 25 million years ago and created the Himalayan mountain range. In fact, the Himalayans are still growing! The next way that mountains are formed is along fault lines.
