What is the average temperature of lava, magma and material in the center of the earth?
Lava, depending on the composition can have eruptive temperatures of 850 degrees C (silica rich) to 1000 degrees C (silica poor). Magma (molten rock in the earth) will likely have temperatures of around 1000 to 1300 degrees C. The center of the earth (which is NOT where lava originates) has a temperature that is estimated to be anything from 4500 to 7000 degrees C. 22. Have there been any volcanic eruptions so violent that rocks or ash from the volcano escaped the earth’s atmosphere? Hmm, I’ll have to think about that for a while. I’m pretty sure that it’s possible, but I don’t know. Here is another good web site for near real-time data from NASA: http://jwocky.gsfc.nasa.gov/aerosols/today_plus/oyama.html 23. What are the differences between andesitic and basaltic lava? Andesitic: SiO2 content is 60 – 70%; these lavas form from the partial melting of wet basalt (subducted oceanic crust); they tend to be viscous (slow flowing) partly because of their composition and partly because of th
