Q:

Quick Answer

A composite cone volcano, or a stratovolcano, is built by multiple eruptions from surrounding volcanoes. They are formed over hundreds of thousands of years and have their entire structure build by magma flowing from geographically close volcanoes.

Full Answer

Composite volcanoes are most often made from andesite magma. This type of magma is composed mostly of fragmented debris and can build up the framework of a composite volcano by knitting together volcanic rubble. Andesite magma can also form cones of magma that are then knit together to form large structural pieces of an entire composite volcano. Well-known composite volcanoes include Mount Fuji, Mount Rainier and Mayon Volcano.

  • Q:

    How do you make a composite volcano?

    A:

    To make a composite volcano, mix vinegar and baking soda together to create a mock eruption. The base in the form of baking soda neutralizes the acid in the vinegar and produces carbon dioxide gas, which causes the mixture to bubble and rise.
