What determines whether a volcano will erupt violently or quietly?
if a volcano is high in silica, it will be explosive. If its low in silica, it will be quiet. Two important things that determine whether an eruption will be explosive or quiet: # The amount of water vapor and other gases that are trapped in the magma. # If the magma is basaltic or grantic.
How would you compare and contrast basaltic and granitic magmas?
Basaltic magmas have a lower silica content and higher temperature than granitic magmas. Basaltic magmas are more fluid and tend to erupt more explosively, while granitic magmas are more viscous and can lead to explosive eruptions due to gas buildup. Additionally, basaltic magmas form oceanic crust, while granitic magmas form continental crust.
What is igneous that have mineral composistions between those grantic and basaltic rocks?
andesitic rock
