eruption are caused by magma building up under the earth and then the relesing the pressure whitch causes lava to shoot up into the air, think of a coke bottle it has the same affect

∙ 12y agoVolcanoes are caused by two or more tech tonic plates colliding and pushing the earth up. If the magma is close to the surface of the earth then it will form a volcano. If it is deep underground it will form a mountain. It can take millions of years to make volcanoes the size of Mt. st. Helena

Causes of volcanicity?
Magma in mantal is under great heat and high temperature. Once there is a crack or we called a line of weakness appears on crust's surface,magma would escae to the surface from mantal.Volcanic ashes,gases and magma would throw out and causes volcanic eruptions.

The study of volcanoes is found under Physical Geography. It is taught in the topic Volcanicity. Which is a part of Orogenesis, ie origin of rocks, volcanoes and other landforms of igneous properties.
What are the positive and negative effects of volcanicity?
The volcanic ash is very fertile and can bring a very good harvest. The pyroclastic flow and the lava is very destractive and can caurse a lot of damedge to the serrounding area.
What is vocanicity?
volcanicity is the process where by magma in the interior of the earth crust forced it way out to the earth surface cause by intense pressure in the interior of the crust there by forcing the earth crust to expand and causing a crack which will intend force it self through flowing out to form hard igneous rocks
What are the effects of volcanicity?
volcanic eruptions may cause mass extinctions or volcanic haze.a mass extinction is when a large number of species die out over a short period of geologic time and volcanic haze is when the gases of an eruption cause a haze and block out sunshine, causing a mass extinction.
