Document Summary
Continental plate connected to an oceanic plate without any subduction is a passive plate i. e. alaska, east of south america. When india collided into china the ocean submerged under china but the front between india and the ocean was passive. Hawaii was a chain of volcanos but there was no subduction, which is usually how volcano arcs are formed. When an island goes below the water is is considered a seamount. Outer core > mantle boundary (not soft solid material) But when heated acts like a lava lamp, bc the density contrast is driven by temp. Volcanoes build above sea level, plate motion pulls volcano off plume -volcanoes go extinct and erodes.
