Compared to a felsic magma a mafic magma has
WebMagma rises upward through the crust because the magma is less dense than the surrounding rock. As bodies of magma rise toward the surface, they can become larger in two ways; because they are so hot, they can melt some of the surrounding rock. Second, as the magma rises, it is forced into cracks in the surrounding rock. Compare magma with … WebCompared to a mafic rock, a felsic rock has a _____ silica content and melts at a _____ temperature. higher; lower.

WebAug 4, 2024 · We argue that the phase transition from quartz to coesite in the felsic rocks may explain the microstructural differences between the studied mafic–ultramafic and felsic rock samples. The presence of coesite, which has a higher strength than quartz, may result in an increase in the bulk strength of felsic rocks, leading to strain localization ... WebWhich is more viscous, mafic magma or felsic magma? Felsic rock has a higher viscosity (stickiness) than mafic rock due to the high silica content, forming polymer chains which inhibit flow ... List analogies for how mafic magmas flow compared to felsic magmas. Mafic magmas are like water (low viscosity) and can cover great distances while ...
