What usually causes extinction events?
An asteroid from space, volcanic eruption, flooding, loss of food, or drought.
What causes volcanic reactions?
moving of tectonic plates and the build up of pressure within the volcanic mountain under the dried up lava which became rock after the previous volcanic eruption
What causes small earthquakes before a volcanic eruption?
The earthquakes are caused by the movement of magma underground and the breaking of rocks by that magma.
Can a volcanic eruption drop the global temperature?
Yes, volcanic eruptions can drop global temperature. The release of sulfur dioxide into the stratospheric aerosol layer causes chemical reactions that reflect the sun's rays away from Earth. It has even been studied as a possible (if not controversial) model for counteracting the effects of global warming from carbon dioxide buildup.
What causes masive climate changes?
global warming, massive (vei8) volcanic eruptions & meterorite hits (ask the dinosaurs)
What are the three main causes of volcanic eruption?
The three main causes of volcanic eruptions are the accumulation of magma beneath the Earth's crust, the buildup of pressure within the magma chamber, and the release of gases trapped in the magma. These factors can lead to explosive eruptions that result in the expulsion of ash, lava, and volcanic gases.
What is the driving force of a volcanic eruption?
Rising magma forced up as the result of plate tectonics, gravity, or what have you places incredible pressure on sides of the volcano and causes it to bulge. When the pressure becomes too great and the volcano rips open to release the pressure, an eruption begins.
What is one possible causes of the volcanic eruption?
One possible cause of a volcanic eruption is the build-up of pressure from molten rock (magma) beneath the Earth's surface. As the pressure increases, the magma finds a pathway to the surface through a volcano, resulting in an eruption.
