What Is A Subduction Zone Quizlet

This type of fracture is more common in older children.

What is a subduction zone quizlet. A mid-ocean ridge or mid-oceanic ridge. A subduction volcano forms when continental and oceanic crust collide. Subduction zones are marked as the deepest parts of the oceans.

Tectonic plates are massive pieces of the Earths crust that. When tectonic plates converge illustrated by the thick black arrows on either side of the image one plate slides beneath the upper plate or subducts descending into the Earths mantle at rates of 2 to 8 centimeters 13 inches per year red-brown slab with skinny arrow shows direction of. The region where an oceanic plate sinks down into the asthenosphere at a convergent boundary between continental and oceanic plates.

Illustration of a subduction zone Types of subduction zones Oceanic-oceanic plate collision subduction and formation of an island arc. The San Andreas fault is a well-known strike-slip transform fault Fig. The oceanic crust melts and migrates upwards until it erupts on the surface creating a volcano.

Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one Variation in density is responsible for the process of Subduction. Subduction Zone The region where an oceanic plate sinks down into the asthenosphere at a convergent boundary between continental and oceanic plates. The Cascadia Subduction Zone is a 600-mile fault that runs from northern California up to British Columbia and is about 70-100 miles off the Pacific coast shoreline.

Earthquakes occur all the time all over the world both along plate edges and along faults. Subduction zones are areas where ocean floor rocks are formed. Subduction consumes lithosphere and since the surface of the earth is a constant it compensates for the amount of lithosphere created at divergent plate boundaries.

Pros Cons of Using Quizlet in Your Classroom. Subduction zone A convergent plate boundary where one plate subducts beneath the other usually because it is denser. Remember oceanic plates are formed from mantle material at midocean ridges.
