MTTC Integrated Science - Earth & Space Sciences Questions And Answers mantle drag plates move due to the friction between the lithosphere and the asthenosphere trench suction involves a downward frictional pull on oceanic plates in subduction zones due to convection currents convergent plate boundary when adjacent plates move toward one another and one plate slips underneath another. three types of formations can come of this 1) oceanic plate + oceanic plate = deep trench 2) continen...

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 - ...

age of earth CORRECT ANSWER our understanding of radioactivity helps us accurately determine numerical dates for rocks that represent important events in earth's past.
