What are volcanic mountains?

A volcanic cone is the triangle-shaped hill formed as material from volcanic eruptions piles up around the volcanic vent, or opening in Earth’s crust. Mount Fuji, Japan, is a classic example of a volcanic cone.

              How are volcanic mountains formed?

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. ... Examples of volcanic mountains include: Mount St.

                                  Types of volcanic cones

The lava blobs in spatter stick together as they land, piling up to form steep-sided spatter cones. Most spatter cones are very small, ranging between 1 and 5 meters (3 to 16 feet) in height, because they result from minor volcanic activity. They often form in linear groups along an eruptive fissure, or long crack, on the flank of an active volcano. A small spatter cone is called a hornito.

Spatter cones can be found in and around the Puʻu ʻŌʻō region of Mount Kilauea in Hawaii. Continuously erupting since 1983, Kilauea’s volcanic activity is characterized by the fountaining of hot lava, making it the perfect incubator for spatter cones.

When heated rapidly by lava, water flashes to steam and expands violently, fragmenting huge amounts of lava into plumes of very fine grains of ash. This ash falls around the volcanic vent, creating an ash cone.
