Volcanic Eruptions
Answers to Common Questions
Yes. Large eruption columns inject ash particles and sulfur-rich gases into the troposphere and stratosphere. The small ash particles decrease the amount of sunlight reaching earth and lower average global temperatures.
Volcanic eruptions happen when the plates have moved enough to allow the hot magma to burst through the surface. This will happen when the gases from the magma have built up enough pressure. Look here for more information: http://library.th...
Volcanic eruptions are caused by the pressure of gas within the earth's crust. Magma is formed when the upper mantle of earth's crust melts under the intense heat. The eruption of gas pushes the magma up, causing the eruption.

Volcano eruptions have occurred shortly after earthquakes and they may be linked, but scientists are still debating the topic. Notably, an Andean volcano (Cordon Caulle) began erupting 2 days after the magnitude 9.5 1960 Chile earthquake.
