Volcanism creates mountains that are:
A) sometimes local and not accompanied by regional increases in crustal thickness
B) formed of piled volcanic material, such as scoria, ash, lava flows, debris flows, and mudslides
C) varied in size from small cinder cones to large shield and composite volcanoes
D) all of these are types of mountains created by volcanism
Scoria
A dark-colored volcanic rock with abundant gas bubbles, typically found around basaltic volcanoes.
Debris Flows
Rapid downhill movement of water-saturated soil, rocks, and vegetation, often triggered by heavy rainfall or rapid melting of snow.
Composite Volcanoes
Volcanoes characterized by explosive eruptions and composed of layers of volcanic ash, lava, and rocks.
- Understand the influence of volcanic processes on the formation of mountains locally and distinguish different varieties of volcanoes.

Final Answer :
D
Explanation :
Volcanism can create mountains through localized events without necessarily increasing the regional crustal thickness. The material that forms these mountains includes scoria, ash, lava flows, debris flows, and mudslides. The size of these volcanic mountains can vary widely, from small cinder cones to large shield and composite volcanoes. Therefore, all the provided options are correct descriptions of mountains created by volcanism.
