Question

write a short note on volcanic mountain and its types

Answer 1

hey mate...
volcanic mountain starts out as a simple crack in the Earth called a volcanic vent. Magma erupts out of the ground as lava flows, clouds of ash, and explosions of rock. This material falls back to Earth around the vent, and piles up around it. Over time (and sometimes quite quickly) a volcanic mountain builds up, with the familiar cone shape.

There are different kinds of volcanic mountains. Cinder cone mountains are made up of material blasted out that rains back down. They don’t usually grow too large. Shield volcanoes are built up by many lava flows of low viscosity lava (low viscosity means that it flows more easily). The lava can flow for dozens of kilometers, and the volcano can be very wide. A stratovolcano or composite volcano is made up of many layers of ash, rock and hardened lava. Some of the largest, most impressive volcanoes in the world are stratovolcanoes (think about Mount Fuji or Rainier).


stratovolcano (or composite volcano) — a conical volcano consisting of layers of solid lava flows mixed with layers of other rock.

cinder cone volcano — doesn’t have any horizontal layers, and is instead a steep conical hill of tephra (volcanic debris) that accumulates around and downwind from the vent.

shield volcano —  a type of volcano built entirely or mostly from fluid lava vents. They are named like this because when viewed from above, you can see just how massive and imposing they are – like a warrior’s shield.

Volcanic Mountains

As the name suggests, volcanic mountains are formed by volcanoes.

Volcanic Mountains are formed when molten rock (magma) deep within the earth, erupts, and piles upon the surface. Magna is called lava when it breaks through the earth's crust. When the ash and lava cools, it builds a cone of rock. Rock and lava pile up, layer on top of layer.

Examples of volcanic mountains include:

Mount St. Helens in North America

Mount Pinatubo in the Philippines

Mount Kea and Mount Loa in Hawaii

volcanoes are of three types active, dormant and extinct.
