Volcanic landforms. Subcategories. This category has the following 33 subcategories, out of 33 total. C. Central volcanoes (1 C, 12 P) Cinder cones (6 C, 43 P)
Resurgent dome – Volcanic landform; Rootless cone, also known as pseudocrater – Volcanic landform; Seamount – Mountain rising from the ocean seafloor that does not reach to the water's surface; Shield volcano – Low-profile volcano usually formed almost entirely of fluid lava flows
Cinder Hill, a feature of Mount Bird on Ross Island, Antarctica, is a prominent example of a dissected volcano. Volcanoes that were, on a geological timescale, recently active, such as for example Mount Kaimon in southern Kyūshū, Japan, tend to be undissected. Devils Tower in Wyoming is a famous example of exposed volcanic plug.
A rootless cone, also formerly called a pseudocrater, [1] is a volcanic landform which resembles a true volcanic crater, but differs in that it is not an actual vent from which lava has erupted. They are characterised by the absence of any magma conduit which connects below the surface of a planet.
Volcanic cones are among the simplest volcanic landforms. They are built by ejecta from a volcanic vent , piling up around the vent in the shape of a cone with a central crater. Volcanic cones are of different types, depending upon the nature and size of the fragments ejected during the eruption.

The most important types of volcanic mountain are composite cones or stratovolcanoes and shield volcanoes. [10] [11] A shield volcano has a gently sloping cone because of the low viscosity of the emitted material, primarily basalt. Mauna Loa is the classic example, with a slope of 4°-6°.
An example is the massive Level Mountain shield volcano in northern British Columbia, Canada, which covers an area of 1,800 km 2 (690 sq mi) and a volume of 860 km 3 (210 cu mi). [ 1 ] Perhaps the most extensive of all the subaerial basaltic plateaus existed during the Paleogene [ 2 ] and possibly extended over 1,800,000 km 2 (690,000 sq mi) of ...
