I know a caldera is technically a tube of lava that sits where a volcano once collapsed. And a caldera is considered a volcanic structure. However is a caldera considered technically as a volcano or simply a leftover volcanic related structure of where a volcano once existed? I know I'm probably over thinking this way to much but I was asked this on a Geography test.

A caldera is a volcano. Some are active, some are dormant, while others are extinct. And it is not a tube of lava. It is a collapse structure formed via the evacuation of a magma chamber during a massive eruption. Once the chamber empties, the roof of the chamber collapses, resulting in the formation of the caldera at the surface.
