What Causes A Volcano?
Magma is always seeping below the earth's crust. Although, some magma may rise to the surface; this creates a volcano. Bubbles of gas are created when the magma rises to the top. This gas causes pressure to stir in the mountain, and makes it explode. After magma reaches the surface of the earth, it is called lava.
The Incident's Impact
Volcanic eruptions are able to affect areas in many different ways. Eruptions can destroy the entirety of a civilization, and have the ability to wipe out nearby species. Although, these catastrophes can also begin primary succession and create habitats on new islands or land. If a community isn't wiped out, the amount of organisms will decrease by a great amount. Biodiversity will decrease as well because of the lack of species. Furthermore, this will cause a ginormous alteration in how organisms collect their energy, which can be shown in their food webs. Food webs will change as numerous species migrate, adapt, or die. Volcanic eruptions have a great effect on the habitats, biodiversity, and food webs.
