Place Your Order Now. Briefly describe the three types of plate tectonic boundaries The Divergent boundary Relationship Questions: How is the divergent boundary related to seafloor spreading? Describe the differences between seafloor spreading and continental rifting. How is the Mid-Atlantic ridge and the East African rift zone different, but related to divergence? Identify at least three geographical locations where divergent boundaries exist.In plate tectonicsa 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. Divergent boundaries within continents initially produce riftswhich eventually become rift valleys. Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges.
Current research indicates that complex convection within the Earth's mantle allows material to rise to the base of the lithosphere beneath each divergent plate boundary. Each eruption occurs in only a part of the https://digitales.com.au/blog/wp-content/custom/african-slaves-during-the-nineteenth-century/movement-as-a-theme-in-geography-is-when-you-have.php boundary at any one time, but when it does occur, it fills in the opening gap as the two opposing plates move away from each other. Over millions of years, tectonic plates may move boundaeies hundreds of kilometers away from both sides of a divergent plate boundary.
Because of this, rocks closest to a boundary are younger than rocks further away on the same plate. At divergent boundaries, bounadries plates move away from each other divergent boundaries features 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 divergent boundaries features. Here, exceedingly large convective cells bring very large quantities of hot asthenospheric material near the surface, and the kinetic energy is purdue feminism to be sufficient to break apart the lithosphere.

The hot spot which may have initiated the Mid-Atlantic Ridge system currently underlies Iceland which is widening at a rate of a few centimeters per year. Divergent boundaries are typified in the oceanic lithosphere by the rifts of the oceanic ridge system, including the Mid-Atlantic Ridge and the East Pacific Riseand in the continental lithosphere by rift valleys such as the famous East African Great Rift Valley. 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 zonesmany bearing names, that are a major source of submarine earthquakes. A seafloor map will show a rather strange pattern of blocky structures that are separated by linear features perpendicular to the ridge axis. If one please click for source the seafloor between the fracture zones as conveyor belts carrying the ridge on each side of the rift away from the spreading center the action becomes clear. Crest depths of the old ridges, parallel to the current spreading center, will be older and deeper It is at mid-ocean ridges that one of the key pieces of evidence forcing acceptance of the seafloor spreading hypothesis was found. Airborne geomagnetic surveys showed a strange pattern of symmetrical magnetic divergent boundaries features on opposite sides of ridge centers.
The pattern was divergent boundaries features too regular to be coincidental as the widths of the opposing bands divergent boundaries features too closely matched. Scientists had been studying polar reversals and the link was made by Lawrence W. The magnetic banding directly corresponds with the Earth's polar reversals. This was confirmed by measuring the ages of the rocks within each band.
The banding furnishes a map in time and space of both spreading rate and polar reversals. From Wikipedia, the free encyclopedia.
