Our system will evaluate the answer based on this AI-generated description.
The image displays a sequential diagram illustrating the development of a supervolcano, featuring five main phases: (1) initial land depression with the distinction of the surface, crust, and mantle layers, (2) formation of a magma chamber below the surface, crust, and mantle, (3) pressurized build-up leading to a fissure, showing the surface, crust, mantle, and magma chamber, (4) eruption phase with visible smoke and lava, indicating magma rises from beneath the surface through the crust and mantle layers, (5) resultant reduced size of the land formation post-eruption with labeled surface, crust, and mantle layers.
Given the complexity of the image, the above description may not be entirely accurate.

The diagram below shows the stages that are involved in the formation of a supervolcano. Four images show the inside of the Earth that is divided in three sections: mantle, crust, and surface.
At the beginning the magma chamber, which is inside the crust, contains all the magma. As the pressure inside the chamber increases, the surface exposes larger fissures that weren’t that deep on the previous stage. In the following stage the crust can’t stand the pressure, so the magma finds a path through the crust until it reaches the surface. As the magma is outside we have what is called “the eruption” where smoke and lava are released. In the final stage the chamber is reduced due to the eruption so the surface collapses and what is left is a land depression visible on the surface.
