E. Creation of volcanoes
How are volcanoes created?
We all know that magma is underneath the earth’s surface, and this is mainly what erupts from a volcano, but it has a different name after it comes out of the vents: lava.
Cinder cone volcanoes are created when the constructive plate boundaries move in opposite directions leaving a big gap in between them. The magma pops out and after it falls down and hardens, a cinder cone volcano is then created.
Stratovolcanoes are created when the destructive plate boundaries overlap each other; the continental plate goes up and the oceanic plate sinks down. This also builds up pressure deep underground with the magma chambers. As the pressure builds up a vent will be opened up to eject the ash and magma into the atmosphere. Then after those volcanic materials fall back and hardens, a stratovolcano is then created.
Shield volcanoes are created when hot spots form and the underground magma and other volcanic materials will then pop up, fall back, hardens, then form a shield volcano between the plates.
