At a spreading boundary the lithosphere is pulling apart, therefore the magma rises through the spreading zone to form a volcano. But since it is constantly spreading, the vol … cano will eventually split and half will go one direction and the other half the opposite direction. Beneath the Earth's crust is a lot of magma. Thus as the plates pull apart, it leaves a gap through which the magma can travel and erupt as lava. For example at the Mid Atlant … ic Ridge, there are divergent plate boundaries. 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. At divergent boundaries, two plates move apart from each other and the space that this creates is filled with new crustal material sourced from molten magma that forms below. The origin of new divergent boundaries at triple junctions is sometimes thought to be associated with the phenomenon known as hotspots. Tectonics and Landforms Plate Boundaries Along the boundary of the Earth's tectonic plates a fiery drama of catastrophic proportions is played out. Movement of the Earth's crust creates earthquake activity and in some places great outpourings of lava extrude onto the surface. Plate Boundaries. As the plates move away from each other at divergent boundaries, the lithosphere becomes thinner. A set of deep cracks form in rift zone.   It is formed by the magma fro … m magma chambers rising at the rifts in the sea floor. Cooling and hardening then occurs. More  commonly, divergent boundaries in the ocea … n occur and cause  mid-oceanic ridges. Divergent boundaries can also form volcanoes  when the plates separate enough to allow molten lava to seep out,  harden, and eventually form islands. 7 people found this useful. To recap, there are three types of plate boundaries that are formed by the interactions of different plates. Divergent boundaries are boundaries where plates pull away from each other, forming mild earthquakes and volcanoes as magma comes to the surface. Convergent boundaries are boundaries where two plates are pushing into each other. They are formed when two plates collide, either crumpling up and forming mountains or pushing one of the plates under the other and back into the mantle to melt. Convergent boundaries form strong earthquakes, as well as volcanic mountains or islands, when the sinking oceanic plate melts. The third type is transform boundaries, or a boundary where plates slide past each other, forming strong earthquakes. Divergent boundaries can also form volcanoes  when the plates separate enough to allow molten lava to seep out,  harden, and eventually form islands. Beneath the Earth's crust is a lot of magma. Thus as the plates pull apart, it leaves a gap through which the magma can travel and erupt as lava. For example at the Mid Atlant … ic Ridge, there are divergent plate boundaries. In the theory of plate tectonics, the earth's crust is broken into plates that move around relative to each other. As a result of this movement, three types of plate boundaries are formed: divergent, convergent, and transform boundaries. Convergent boundaries form strong earthquakes, as well as volcanic mountains or islands, when the sinking oceanic plate melts. The third type is transform boundaries, or a boundary where plates slide past each other, forming strong earthquakes. In plate tectonics, divergent boundaries occur when plates pull  apart. On land, divergent boundaries form rifts or valleys. More  commonly, divergent boundaries in the ocea … n occur and cause  mid-oceanic ridges.
