Web2 apr. 2024 · The least explosive type of volcano is called a basalt plateau.These volcanoes produce a very fluid basaltic magma with horizontal flows. The form of these volcanoes is flat to gently sloping and they can occupy an area from 100,000 to … WebMost felsic magma will stay deeper in the crust and will cool to form igneous intrusive rocks such as granite and granodiorite. If felsic magma rises into a magma chamber, it may be too viscous to move and so it gets stuck. Dissolved gases become trapped by thick magma. The magma churns in the chamber and the pressure builds. Eruptions The type ...

WebHere we are concerned with the silica that is dissolved in the liquid part of magma. Magma-the name for lava before it erupts--is strongly influenced by its viscosity. Viscosity is the resistance to flow in a liquid. A liquid is said to have a high viscosity if it flows slowly and a low viscosity if it flows freely. http://sci.sdsu.edu/how_volcanoes_work/Controls.html

Viscosity is important in volcanology. An eruption of highly viscous (very sticky) magma tends to produce steep-sided volcanoes with slopes that are about 30–35°. That’s because the viscous volcanic material doesn’t flow that far from where it is erupted, so it builds up in layers forming a cone-shaped … Meer weergeven Where a volcano produces low viscosity, runny lava, it spreads far from the source and forms a volcano with gentle slopes: a shield volcano. Most shield volcanoes are formed from … Meer weergeven Stratovolcanoes have relatively steep sides and are more cone-shaped than shield volcanoes.
