a volcano
A mountain formed by the build up of lava and ash is a composite volcanic cone.
the magma(lava) builds up a mountain that soon becomes a volcano.and this is how it happansKelsey Grace Frazier
It is constructive: the lava builds into a new structure.
Mount Fuji is a Volcanic mountain formed from volcanic vents in the Earth's crust that builds up over time when magma comes out as lava on the Earth and dries up into rock.
A volcano is a mountain from which lava flows out during an eruption.
Lava may form a mountain called a volcano!
islands ( Lava from volcano dries up and creates igneous rock forming islands) peninsulas( also lava builds up and creates igneous rock and main land builds up) Mountains ( lava builds up near an active volcano when ever volcano erupts more building up is caused until mountain is created) that's all I CAN think of. Don't blame me sorry hoped this helped though I did all the research I could
A volcano is a mountain that opens downward to a reservoir of molten rock below the surface of the Earth. When pressure builds up, eruptions occur, spewing lava, ash, and gases.
A mountain that forces out gases and lava into the air is known as a volcano. When pressure builds up from molten rock, or magma, beneath the Earth's surface, it can erupt explosively or effusively, releasing ash, gases, and lava. Volcanoes can shape landscapes and have significant impacts on the environment and climate. Notable examples include Mount St. Helens in the U.S. and Mount Vesuvius in Italy.
A volcano can be a cone-shaped mountain that is built from layers of lava.
Mount Fuji is a Volcanic mountain formed from volcanic vents in the Earth's crust that builds up over time when magma comes out as lava on the Earth and dries up into rock.
Deep inside Earth, magma flows out of Earth as lava. The lava cools down as layers. As more and more layers form, a volcanic mountain forms.There are a some good facts about Volcanic Mountains. Volcanic mountains is a mountain that goes down into a molten rocks, after a while the volcano spills lava everywhere and also when a volcano explodes lava can go for 20 miles.
