Subduction Of The Ocean Floor Takes Place

Subduction of the ocean floor takes place at trenches.

Subduction of the ocean floor takes place.

For example there is a major fault line off the western coast of south america. Ocean floor fall into trenches and also where subduction takes place. How do moving plates change earth s crust. In what boundary do 2 plates pull apart.

The lower mantle b. Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle. In what areas does the subduction of the ocean floor take place. Sea floor spreading takes place at the mid ocean ridge where two oceanic plates are spreading pulling apart from one another.

Spreading rate is the rate at which an ocean basin widens due to seafloor spreading. Earthquakes take place primarily on fault lines. Subduction of the ocean floor takes place at. Spreading rates determine if the ridge is fast intermediate or slow.

Subduction of the ocean floor takes place at a. The rate at which new oceanic lithosphere is added to each tectonic plate on either side of a mid ocean ridge is the spreading half rate and is equal to half of the spreading rate. Takes place at underwater canyons and it allows the ocean floor to seem wider. 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.

Made of rocks such as granite. 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. Slow movements of mantle rock that transfers heat in the mantle. The process that powers plate tectonics a.

A device the uses sound waves to measure the distance to an object. Subduction occurs here due to the ocean floor being of denser rock. Allows part of the ocean floor to sink into the mantle. The process that powers plate tectonics is.
