Volcanoes form when magma reaches the Earth's surface, causing eruptions of lava and ash. They occur at destructive (compressional) and constructive (tensional) plate boundaries. The immediate effects of volcanic eruptions can be devastating, but they may be beneficial in the long term.
Karine Adria, Gamer. Views. If you mean will Mount Everest ever erupt lava like a volcano then no. It is a mountain part of the Himalayan range which is an orogenic mountain belt formed as a result of a continental collision along the convergent plate boundary between the Indo-Australian Plate and the Eurasian Plate. The process of how volcanoes are formed is totally different. Volcanoes are formed when magma from within the Earth's buoyant upper mantle rises and leaks onto the Earth's crust as volcanic eruptions which happen at destructive or constructive plate boundaries.
