The type of magma associated with oceanic hot spots - mafic Decompression melting in this setting forms a long, submarine ridge - divergent boundary When mafic magma rising from the mantel rises through this type of crust, it will form int-felsic magma - Continental crust Shield volcanoes may form here, when magma upwells from the asthenosphere - hot spot The type of magma that most commonly forms at subduction zones - int-felsic magma This tectonic setting can form an explosive caldera - ...

EES Exam 2 Questions and answers. Latest Update. Verified. Is all volcanic activity violent and explosive? - -No What is magma? - -Melted rock material How does magma vary? - -It varies in composition. Some can have more silica than others. Silica content - -Silica makes magma more viscous because silica tetrahedra link together. Gas content - -Different dissolved gases, such as H2O and CO2, can control how a volcano erupts. What is the difference between rhyolitic and basalt...
