WebThe temperature of lava flow is usually about 700° to 1 250° Celsius which is 2 000° Fahrenheit. Deep inside the earth usually at about 150 kilometers the temperature is hot enough that some small part of the rocks begins to melt. Once that happens the magma (molten rock) will rise toward the surface (it floats). WebJul 7, 2024 · Viscosity depends on primarily on the composition of the magma, and temperature. Higher SiO 2 (silica) content magmas have higher viscosity than lower SiO 2 content magmas (viscosity increases with increasing SiO2 concentration in the magma). Advertisement Which of the following increases the viscosity of magma?

Did you know?

http://sci.sdsu.edu/how_volcanoes_work/Controls.html WebMagmas with higher silica concentration are more viscous, and thus move slower than magmas with less silica. Where tectonic plates come together, volcanoes often have thicker, viscous magma with high gas content. This combination is explosive because the gases cannot easily boil out.

WebWhy does the silica content (the amount of linked tetrahedra) of magma matter so much? A large amount of linked silica tetrahedra will result in magma or lava that is very viscous, meaning that it cannot flow easily (viscosity means resistance to flow). The temperature … 7.
