Geosphere

Explanation:

Volcanoes are geological structures made up of molten rock, due to the high temperatures inside. Basically they represent an opening in the Earth's surface capable of expelling magmatic material and gases coming from the interior of the planet. They are geosphere events.

Volcanic eruptions can cause a lot of destruction, especially when your area is inhabited. Not every region on the planet has volcanoes, and their formation and distribution are related to the existence of tectonic plates.

Visually, volcanoes resemble mountains and can even be confused, especially when they are inactive. However, they are different structures from their formation to their composition.
