ocean-continent convergence
The Andes Mountains :) ***** I would like to add the Himalayas, which rose when the Indian Plate collided with the European plate.
At a continent-continent convergence, two continental plates collide, leading to the formation of mountain ranges through the process of continental collision. This collision results in intense folding and faulting of the Earth's crust, causing earthquakes and creating new mountain chains, such as the Himalayas.
folded mountains are produced
When two continents converge, they often form mountain ranges due to the collision of their landmasses. This can also lead to intense geological activity such as earthquakes and volcanic eruptions. Over time, the continents may continue to collide and push against each other, causing further changes to the landscape.
Folded mountains form
Ocean convergence with continental plates result in subduction zone. Oceanic with oceanic plates convergence forms volcanic mountain.
This would depend on the type of boundary: ocean-ocean, continent-continent, or ocean-continent. For ocean-ocean crusts, the slab of crust "forced down" is being subducted. Besides bringing water inside the rock and lowering its melting temperature, this could produce an ocean trench. For continent-continent convergence, the "subducted" plate does not go very far. Because of the buoyancy of continental crust and its lightweight nature (as compared to oceanic crust, which is very dense), the plates tend to buckle and create tall mountain ranges. For continent-oceanic convergence, such as the Western cost of South America, oceanic crust is forced down and is subducted underneath continental crust. This creates mountain ranges as well, and also forms the mechanism from which igneous intrusions can make their way to the surface of the crust.
