Volcanic Landforms study guide
Volcanic eruptions create landforms made of lave, ash, and other materials. These landforms include shield volcanoes, cinder cone volcanoes, composite volcanoes, and lava plateaus.
Another landform is a caldera.
1.
Shield volcano : a wide, gently sloping mountain made of layers of lava and formed from quiet eruptions.
2.
Composite volcano : A tall, cone-shaped mountain in which layers of lava alternate with layers of ash and other volcanic materials.
3.
Cinder-cone volcano : A steep, cone-shaped hill or small mountain made of volcanic ash, cinders, and bombs piled up around a volcano’s opening.
4.
Lava Plateau: When lava flows out of several long cracks in an area and thin, runny lava travels far before cooling and solidifying. Floods of lava flow on top of earlier floods creating a plateau comprised of lava.
5.
Caldera: The large hole at the top of a volcano formed when the roof of a volcano’s magma chamber collapses.
6.
Volcanic neck : A deposit of hardened magma in a volcano’s pipe.

7.
Dome Mountain: A dome mountain forms when uplift pushes a large body of hardened magma toward the surface.
The hardened magma forces layers of rock to bend upe4ward into a dome shape.
8.
Sill: A slab of volcanic rock formed when magma squeezes between layers of rock.
9.
Dike: A slab of volcanic rock formed when magma forces itself across rock layers.
10.
Batholith: A mass of rock formed when a large body of magma cools inside the crust.
11.
What are three features formed from magma?
Volcanic neck, dike, sill, batholiths, and dome mountain
12.
How does a caldera form?
A large eruption can empty the main vent and magma chamber beneath the volcano. With nothing to support it, the mountain collapses, forming a caldera.
