- Volcanism is the study of volcanoes. Volcanoes are found at hot spots, where tectonic plates are converging or diverging.
- Volcanoes are caused differently, but they all occur because of the building pressure under the surface.
-During the eruption of a volcano not only does lava come out, many greenhouse gases are released into the air resulting in the greenhouse effect.
-Accompanying the eruption factors of lava and gas, an abundant amount of dirt and ash are released into the air, which sometimes can lead to the haze affect, which is when the sun is blocked out by dirt.
