where can i find subduction zones
The next is volcanic activity as a plate is subducted the pressure and heat turns it into magma. These pockets of magma find paths to the surface and create volcanoes. A good example is the subduction zone near Chile. The final sign is deep marine trenches. These are the best evidence of a subduction zone as they are visible evidence of the crease formed by subduction of a plate.
A subduction zone is a region of the Earthâs crust where tectonic plates meet. Tectonic plates are massive pieces of the Earthâs crust that interact with each other. The places where these plates meet are called plate boundaries.
