what is the process of a volcano? explain urgent need
Answers
Volcanic processes are related to the eruption of molten rocks, known as magma, through central vents or fissures onto the surface. They include all the processes that result from intrusion into bedrock and extrusion onto the Earth's surface. These processes have contributed to the construction of landforms and features of the Earth's surface over millions of years. These processes are important to geomorphologists because they change the surface of the Earth by creation of volcanic landforms and intrusion of new magma into the Earth's crust.

Answer:
a volcano is a sudden opening in the crust of the earth, caused by the earths interior movements. a volcano mountain forms when molten rock material from earth science mantle forces it's way through the crust and accumulates like a cone to form volcanic ridges and mountains. this hot molten rock material appearing at the surface of a volcano is called lava. it contains hot gas,ash and small stones. volcanoes usally form near hotspots within the earth s crust or at the boundaries of tectonic place.
