Divergent Boundary-This occurs when two tectonic plates move away from each other. 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.What two plates are moving away from each other?
In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.What landform is created when two plates move apart?
Volcanoes and ridges are landforms that are created by the movement of tectonic plates. Some volcanoes are formed when the plates pull apart under the ocean. A crack in Earth's crust forms. Magma rises through the crack, forming ridges.
