Subduction of the ocean floor takes place at trenches.
Subduction of the ocean floor takes place.
Regions where this process occurs are known as subduction zones rates of subduction are typically measured in centimeters per year with the average rate of convergence being.
Sea floor spreading takes place at the mid ocean ridge where two oceanic plates are spreading pulling apart from one another.
Ocean floor fall into trenches and also where subduction takes place.
Spreading rates determine if the ridge is fast intermediate or slow.
The process that powers plate tectonics a.
A device the uses sound waves to measure the distance to an object.
Made of rocks such as granite.
The process of the ocean floor sinking beneath ocean trenches and into the mantle.
The lower mantle b.
Subduction occurs here due to the ocean floor being of denser rock.
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.
How do moving plates change earth s crust.
Earthquakes take place primarily on fault lines.
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.
The process that powers plate tectonics is.
Subduction of the ocean floor takes place at a.
In what areas does the subduction of the ocean floor take place.
In what boundary do 2 plates pull apart.
Takes place at underwater canyons and it allows the ocean floor to seem wider.
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.
Slow movements of mantle rock that transfers heat in the mantle.
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.
For example there is a major fault line off the western coast of south america.
Spreading rate is the rate at which an ocean basin widens due to seafloor spreading.
