WebHow is magma formed in subduction zones? As a tectonic plate slides into the mantle, the hotter layer beneath Earth’s crust, the heating releases fluids trapped in the plate. These fluids, such as seawater and carbon dioxide, rise into the upper plate and can partially melt the overlying crust, forming magma. WebCase Scenario 2: Volcanic Eruption in a Subduction Region. Description: Regions near subduction zones often have active volcanoes. Volcanic eruptions can occur due to the process of volcanism that occurs in the subduction zone. These eruptions can cause environmental damage, and can endanger the safety of people around the area.
