The occurrence of the process of mountain

Nurhaeni
The mountain is due to the tectonic forces at work in the earth called orogenesis and epeirogenesis. In the process of orogenesis these sediments accumulated to change shape as it gets compressive force of the collision of tectonic plates. There are three types of collision of tectonic plates, the plates arc of islands and continents, oceans and continents, and between the continent to continent. Ocean and continental plate collisions cause marine sedimentary deposits on the continental shelf edge. Collision between continental plates resulted in island arc with the ocean plate asthenosfir infiltrated layer and volcanic rocks and sedimentary deposits on the continent and become involved in the Sierra Nevada mountains in California in the Mesozoic era. While the continental shelf to the continental collision is the formation of the Himalayan system and the Ural
