Divergent Boundary Introduction. A divergent boundary is an area where two crustal plates are separating. Most of these tectonic plate boundaries are located on the floor of the oceans. The separating plates form rift valleys on the ocean floor where there are weaknesses in the crust. New oceanic crust. The weaknesses in the crust allow molten lava to move toward the Earth's surface on the ocean floors.

- A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, lava spews from long fissures and geysers spurt superheated water. Frequent earthquakes strike along the rift.Beneath the rift, magma—molten rock—rises from the mantle. divergent boundary occurs when two tectonic plates move away from each other.

There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. Magma rises into and through the other plate, solidifying into new crust. Magma formed from melting plates solidifies into granite, a light colored, low-density rock that makes up the continents. Thus at convergent boundaries, continental crust, made of granite, is created, and oceanic crust is destroyed.Two plates sliding past each other forms a transform plate boundary. Natural or human-made structures that cross a transform boundary are offset—split into pieces and carried in opposite directions.agma rises into and through the other plate, solidifying into new crust.

Divergent plate boundaries Divergent plate boundaries. One young divergent plate boundary that you'll recognize is actively forming the Red Sea. Although the Arabian penninsula and Africa were once linked to form a single continent, they are now being ripped apart. The white arrows show the directions the two plates are moving. You can see that a new ocean, the Red Sea is being formed as they separate.

- 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.t 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.

Divergent boundary 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.ivergent boundaries are typified in the oceanic lithosphere by the rifts of the oceanic ridge system, including the Mid-Atlantic Ridge and the East Pacific Rise, and in the continental lithosphere by rift valleys such as the famous East African Great Rift Valley.

- 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.

There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. Thus at divergent boundaries, oceanic crust, made of basalt, is created. When two plates come together, it is known as a convergent boundary. The impact of the two colliding plates buckles the edge of one or both plates up into a rugged mountain range, and sometimes bends the other down into a deep seafloor trench.

Divergent boundary In plate tectonics, a divergent boundary or divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts which eventually become rift valleys. Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Divergent boundaries also form volcanic islands which occur when the plates move apart to produce gaps which molten lava rises to f

Earth Science in Maine In convergent/destructive plate boundaries, two plates collide into each other. They may form mountains, mountain ranges, volcanoes and many other landforms. In divergent/constructive plate boundaries, two plates move away from each other. They can form mid-ocean ridges, island arcs and many other landforms. When a small volcano explodes at or in sea the lava cools and forms a hard surface and forms mountains, Plautus.

- A subduction zone is formed at a convergent plate boundary when one or both of the tectonic plates is composed of oceanic crust. The denser plate, made of oceanic crust, is subducted underneath the less dense plate, which can be either continental or oceanic crust.escriptions [edit]. The nature of a convergent boundary depends on the type of plates that are colliding. Where a dense oceanic plate collides with a less-dense continental plate, the oceanic plate is typically thrust underneath because of the greater buoyancy of the continental lithosphere, forming a subduction zone.

Plate Boundaries: Convergent, Divergent, and Transform Boundaries Plates also can pull apart from each other. This is known as a divergent boundary. A divergent boundary is a fault where the two plates are moving away from each other. Now, as plates pull apart, several things may occur.First of all, volcanic activity is common in these areas since mantle easily moves to the surface through the thin, fractured rock as it separates.lates also can pull apart from each other. This is known as a divergent boundary. A divergent boundary is a fault where the two plates are moving away from each other. Now, as plates pull apart, several things may occur.

Ridges. Opposite of a convergent boundary, a divergent boundary is formed by the spreading of a tectonic plate. This process feeds magma to the surface, creating new crust. Divergent zones in oceanic plates form a geological feature called a ridge, forced upward by the pressure of the rising magma.

Types of Geography Features at a Plate Boundary Ridges. Opposite of a convergent boundary, a divergent boundary is formed by the spreading of a tectonic plate. This process feeds magma to the surface, creating new crust. Divergent zones in oceanic plates form a geological feature called a ridge, forced upward by the pressure of the rising magma.n example of this type of geological feature is the East African Rift Zone. This particular rift zone is called a triple junction because it represents the divergence of three plates, forming a Y shape. The plates involved are the Arabian Plate, and the two African Plates, the Nubian and the Somolian.

Divergent boundary Divergent boundaries can create massive fault zones in the oceanic ridge system. Spreading is generally not uniform, so where spreading rates of adjacent ridge blocks are different, massive transform faults occur. These are the fracture zones, many bearing names, that are a major source of submarine earthquakes.
