Subduction of the ocean floor takes place at a.
Subduction of the ocean floor takes place a.
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.
For example there is a major fault line off the western coast of south america.
Subduction of the ocean floor takes place at.
Which of these parts of the deep ocean floor is flat and nearly featureless.
Subduction occurs here due to the ocean floor being of denser rock.
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.
Rate of seafloor spreading.
Earthquakes take place primarily on fault lines.
The lower mantle b.
Made of rocks such as granite.
The process of the ocean floor sinking beneath ocean trenches and into the mantle.
Spreading rate is the rate at which an ocean basin widens due to seafloor spreading.
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.
The process that powers plate tectonics is.
Globally the rate of seafloor spreading takes place at the same rate as.
Slow movements of mantle rock that transfers heat in the mantle.
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.
Subduction of the ocean floor takes place at trenches.
Two plates collide with each other at.
How do moving plates change earth s crust.
Marine magnetic anomalies can be used to estimate the.
The process that powers plate tectonics a.
Subduction zones occur at.
In what boundary do 2 plates pull apart.
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.
In what areas does the subduction of the ocean floor take place.
Spreading rates determine if the ridge is fast intermediate or slow.
A device the uses sound waves to measure the distance to an object.
