Web“Modeling Seafloor Spreading” Lesson Plan 4 Bay Area E-STEM Institute – BAESI.org Seafloor is constantly destroyed in subduction zones (aka convergent plate boundaries).New seafloor is made from magma (liquid rock) that rises from the mantle and cools to form solid igneous rocks. The Earth has a magnetic field, which is thought to arise WebIt is characterized by rising hot mantle and sinking colder material that forms convection currents that causes the plates to move. In summary, divergent boundary happens when two tectonic plates move away or split away from each other. Seafloor spreading occurs and mid- ocean ridge is formed in this type of boundary.
