Connect In The Middle

"7.  Have you ever wondered what the inside of a volcano looks like?  Deep underground is a magma chamber.  The magma chamber is under the bedrock of the earth's crust.  The conduit or pipe runs from the magma chamber to the top of the volcano.  The conduit connects the magma chamber to the surface.  Most volcanoes also have a crater at the top.  Volcanoes are quite a sight, and you can enjoy this site all over the universe.  Volcanoes are found on planets other than Earth, like the Olympus Mons on Mars.
