Which geographic effect is caused as result of the Nazca plate subducting under the South American plate?

💡 Explanation

When the Nazca plate subducts under the South American plate, gravitational force pulls the denser oceanic crust downward because differential density exists, thereby creating the Peru-Chile Trench, a deep oceanic trench. Therefore, a deep oceanic trench forms, rather than shield volcanoes, rift valleys or symmetrical magnetic patterns, which arise from different geolocial features.
