Composite Cone Volcanoes
Here’s a fun science experiment to make your own composite cone volcano. You may want to do this outside because things can get messy. Put two spoonfuls of baking soda and a spoonful of dish soap into a plastic bottle. Then, add about some vinegar into the bottle. Pretty cool, huh?
What is a composite cone volcano?
What causes a composite cone volcano?
Different types of magma can create a composite cone volcano. The magma sneaks into the cones through cracks and fractures in order to form sills. Sills are made out of igneous rock. Lots of sills eventually form a volcano! The most common kind of magma that causes a composite cone volcano is andesite magma.
How tall can they be?
Where do they form?
Many composite cone volcanoes form in chains, normally at least 10 miles apart. A popular example of this is the “Ring of Fire”, which is along the Pacific Rim.
