Holes in the ground which generate steam or hot gases from below. Often harnessed to make electricity in areas of active volcanism.
A fountain of water and steam that builds up pressure underground and erupts at regular intervals.
Extrusive volcanic Features
Those landforms formed by vulcanism that are created AT the surface, can be small or major features
A low, flat, gently sloping volcano built from many flows of fluid, low-viscosity basaltic lava
The most common volcano. Known for its layers of lava flows and cinder. Built up by violent eruptions that leave the tephra followed by calm eruptions that leave lava flows. They build tall and steep volcanoes.
a large crater caused by the violent explosion of a volcano that collapses into a depression
a wide, flat landform that results from repeated nonexplosive eruptions of lava that spread over a large area
Volcanic features fomed where magma is cooled INSIDE the Lithosphere to be later exposed by denudation
Thin vertical veins of igneous rock that form when magma enters and cools in fractures found within the crust.
