Three Main Types of Volcanoes

Can you name the type of Justin’s

volcano ?

Justin is about to make an eruption of his Composite Volcano. Justin made the volcano with a kit. On the creative side Justin added moss for the grass effect and colored the poster board to add a realistic feel.

Look at a cool

eruption by

Alexandria

In order for the Cinder Cone volcano to erupt with a slow yet vicious lava flow is to add: - liquid dish soap- baking soda- vinegar- food coloring

* The liquid dish soap is added to allow a continuous foamy flow that appears life-like.

Concept of Volcanoes A volcano is a vent or an opening on the surface of the earth’s crust that allows hot magma, volcanic ashes and gases to escape from below the earth’s surface.

Volcanoes are mostly found where the tectonic plates are diverging or converging. Tectonic plates are nothing but the large scale motion of earth’s lithosphere.

Volcanoes can also form at places where the earth’s crust is thin and stretched.
