These fragmented plates … Web4 jul. 2024 · When the plates move apart, a fissure opens up and the molten rock rushes from the mantle to the surface. The opening or fissure helps lower the pressure of the mantle layer and allows the molten material to the surface. The molten rock then solidifies to create a new surface crust.
