[00:00] There are three main ways a volcano can die. The first is if its supply of magma fizzles out. The pushing together or pulling apart of tectonic plates can cause magma to form. But when those plates fuse together, the magma-forming activity stops, snuffing out the
[00:15] volcano. The second way a volcano can die is if it gets dragged away from its magma supply. Sometimes, weird conditions in specific places can melt the mantle, sending up a plume of melting mantle rock, known as a hotspot, that pools beneath the crust and can birth a volcano.
[00:31] The hotspot itself doesn't ever move, but the Earth's crust above it does, so the volcano will eventually leave its magma supply behind. The third way a volcano can die is if it gets clogged. Like if conditions in the mantle change and the magma flow slows down, the magma that's
[00:45] already in the volcano's vents can cool, hardening into a giant plug. Or if the volcano's vents somehow get damaged, the magma might not be able to escape. Of course, it's really really hard to tell exactly what's going on underneath a volcano,
[00:58] so we're not always sure what has happened to a volcano. In fact, sometimes it's hard to tell whether a volcano is actually dead. Instead, they could be taking magmanificently long naps.
