Q:

What are cinder cone volcanoes made of?

A:

Quick Answer

Cinder cone volcanoes are made of material called scoria, a low density form of basalt. Scoria forms as gases in the lava try to force their way out of the molten material through a vertical path.

Full Answer

As the gas escapes, it carries lava high in the air. This ash material then cools into rock filled with air pockets before it strikes the ground forming a cone around the vent without sticking together. Lava rock from cinder cone volcanoes is popular in landscaping. The red rock is a lightweight material that is easy for the landscaper to transport and spread. In the United States, cinder cone volcanoes are visible in California, Oregon and Hawaii.

  • Q:

    What is a cinder cone volcano?

    A:

    According to the U.S. Geological Survey, a cinder cone is the simplest type of volcano, built up out of lava deposits left by a single magma vent. When the vent blows lava into the air, fragments cool and solidify, falling to earth around the vent. Over time, these deposits build up into a cone-shaped hill.
