Composite Volcano

A composite volcano is also called a stratovolcano. This type of volcano is formed when runny lava escapes through a fissure and flows a long way. All stratovolcanoes erupt in different ways at different times. This volcano is built in layers by many eruptions, sometimes recurring aver hundreds of thousands of years. It is constructed of alternating layers of pyrodastic and rock from lava flows.
Composite volcanoes are tall, cone-shaped mountains, and are typically steeply-sided. The essential feature of this volcano is a conduit system. A conduit system is made up of magma from a reservoir deep in Earth's crust that rises to the surface. Most composite volcanoes have a crater at the summit which contains a central vent.
In the picture above, it is showing the inside view of a composite volcano. As I said above, there are many alternating pyrodastic layers. Magma is stored in the magma pool, and when the magma comes out, it goes through the lava flow into the filled central vent.
Here are some examples of composite volcanoes:
Mount Saint Helens
Mount Rainer
Mount Vesuvius
Mayon Volcano
Mount Fuji
Mount Cotopaxi
Mount Shasta
Mount Hood
