Subduction and obduction similarities and differences. Subduction is a process in which a lithospheric plate sinks under the edge of another, the product of a collision between them. The obduction presents a totally opposite effect, where the collision of the plates does not end up sinking them because they are relatively similar. Subduction is responsible […]
What is subduction? Subduction, from Latin for “carried underneath,” is a term used for a specific type of plate interaction. It occurs when one lithospheric plate meets another, that is, in convergent zones, and the denser plate sinks into the mantle.
