The process of the ocean floor sinking beneath ocean trenches and into the mantle. The deepest parts of the ocean floor are caused by plate tectonic subduction and occur where the sea floor sinks back into the mantle in a subduction zone. A device the uses sound waves to measure the distance to an object. The place where subduction has occurred however does not result in the formation of mountains.

In what areas does the subduction of the ocean floor take place. Earthquakes take place primarily on fault lines. This place is known as a subduction zone. In fact this area has seen the eight most powerful earthquakes ever recorded and is home to over 75 percent of the world s active and dormant volcanoes.

For example there is a major fault line off the western coast of south america. Marine magnetic anomalies can be used to estimate the. The lower mantle b. Subduction caused volcanism and earthquake activity occur frequently along the outer edges of the pacific ocean in an area known as the pacific ring of fire.

How do moving plates change earth s crust. What are the two sources of heat in the earth s mantle. Plate motions are the visible part of what process. Subduction zones occur at.

Subduction occurs here due to the ocean floor being of denser rock. Which of these parts of the deep ocean floor is flat and nearly featureless. Subduction of the ocean floor takes place at a. The process that powers plate tectonics a.

In what boundary do 2 plates pull apart. Sea floor spreading takes place at the mid ocean ridge where two oceanic plates are spreading pulling apart from one another. The subduction process is credited with being the single largest contributor behind the theory of plate tectonics. Globally the rate of seafloor spreading takes place at the same rate as.
