WebJan 5, 2024 · The answer is no, because the more silicic magmas are always more viscous than the less silicic ones at a given temperature: a 1000 °C andesite will flow less easily than a 1000 °C basalt. Lastly, let's consider gas content. Without a significant amount of gas, even the most viscous magma will not make a big bang, but just ooze out slowly. WebAs magma rises and pressure is released, gas bubbles (mainly of water vapor and carbon dioxide) form and expand rapidly, causing explosions. Magmas with high silica content tend to erupt violently, because they are viscious.
