GEOL 101exam Question & Correct Answer (100% Verified) 2024 Updates Convergent - CORRECT ANSWER-coming together- there is a subduction of one of the plates and it is being destroyed as it goes down-- the subduction pushes the magma up creating either an island volcano (if with water) or a volcano on land What happens when a convergent boundary forms - CORRECT ANSWER-Any time you have subduction there is going to be a trench, in water, and some sort of volcanic activity Ocean Submerge...

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 - ...
