Employee Assistance Programs | EAPS 100 Exam 1 The point where oceanic crust begins sinking in subduction zones is marked by what type of topographic feature? A deep canyon known as a 'trench' What is the key process that causes the ocean crust to be pulled into the Earth's mantle? Metamorphism transforms the basalt that forms ocean crust into a rock that is more dense than the Earth's upper mantle. This transition pulls oceanic crust downward as it sinks. We now think that plate tectonics...

One process that occurs only at convergent plate boundaries - Answer- Subduction -Volcanic eruptions produce a number of different hazards, including lava flows, pyroclastic flows and gas eruptions as well as secondary hazards such as lahars and jokulhaups. The main reason volcanic eruptions vary in magnitude is as a result of the type of volcano that is erupting which will produce various hazards to differing degrees. Magnitude is mainly measured by the VEI that measures things such as the v...

Volcanoes: Ring of Fire - answer-Exists because of spreading of sinking plates at plate boundaries interact with other Earth materials to produce rocks. Volcanic Vents - answer-An opening through which lava and other volcanic materials are extruded onto the surface. Volcanoes: Decompression Melting: - answer-Overlying pressure exerted on hot rock within the asthenosphere is decreased. Magma will begin to form even though the temperature is constant. Volcanoes: Decompression Melting: Hot...
