Web23 dec. 2024 · Which type of magma is the most viscous? rhyolitic magma The magma that has the highest viscosity is rhyolitic magma. One of the main reasons for the high … WebMafic magma produces high volume, slow moving, effusive eruptions. It forms within the upper mantle, much deeper than felsic magma. Because of the depth, it is hotter and contains more high density materials, such as iron and magnesium. These differences cause lower viscosity (more "runny") and darker color than felsic magma. tax prep fees itemized deduction

Web12 jul. 2024 · Viscosity is the resistance to flow (opposite of fluidity). Viscosity depends on primarily on the composition of the magma, and temperature. Higher SiO2 (silica) content magmas have higher viscosity than lower SiO2 content magmas (viscosity increases with increasing SiO2 concentration in the magma). Advertisement Still have questions? WebA shield volcano is a broad, gently sloping volcano constructed of solidified lava flows. The low viscosity of its lava allows the flows to spread out into wide, thin layers, producing a flattened dome shape or shield. Cinder cone is a volcano constructed of pyroclastic fragments ejected from a central vent. WebLandforms of this sort consist of steep domal mounds of lava so viscous that the lava piles up over its vent without flowing away. The rock types that form lava domes are generally andesites, dacites, or rhyolites. Somehow these viscous lavas have lost much of their gas content in prior eruptions or during a slow rise to the surface. Even so, it is not unusual … the crichton group tn

"WebAs mentioned earlier, mafic magmas are lower in silica and are therefore characterized as having a low viscosity. As mafic magma erupts on to the surface through a central vent (see Figure 9.6, and photo in Figure 9.3), the magma (now called lava) will spread out quite easily due to its low viscosity.

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.
