1 Volcanic mountains-Mountains that are caused by volcanic activity are called volcanic mountains. 2  There are two main types of volcanic mountains: volcanoes and dome mountains. 3  Volcanoes are formed when magma erupts all the way to the surface of the Earth. 4  The magma will harden on the Earth's surface, forming a mountain.
The Himalayas, one of the tallest mountain ranges in the world, is an example of a geological feature that is formed when continental plates collide. Ridges. Opposite of a convergent boundary, a divergent boundary is formed by the spreading of a tectonic plate. This process feeds magma to the surface, creating new crust. Divergent zones in oceanic plates form a geological feature called a ridge, forced upward by the pressure of the rising magma.
