This formation of new land results from the ocean floor rising. What Happens When New Islands Form. Subduction earth movements is the cause of new underwater islands and results in a displacement of ocean water. It happens when an ocean plate slides beneath a continental plate.
Water in the sinking plate eventually leaves the crust and rises into the wedge of the mantle above it. As a result the mantle practically melts. The magma that forms as a result rises up. This magma can break through the ocean floor, causing an island arc. The curve of the island arc imitates that of a mid-ocean trench. Also where oceanic plate is subducted under continental.
