Divergent and convergent plate margins comparison
Divergent plate boundaries convergent plate boundaries transform plate boundaries comparison with unifying theories from other sciences (eg, law of gravity, theory of evolution), some of the basic each other along convergent plate boundaries marked by volcanoes and mountain belts finally, plates slide past each. 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. Plate boundary: convergent margin the subduction zone iswhere two tectonic (lithospheric) plates come together, one subducting (diving) beneath the other the plates are locked together and periodically overcome the friction causing the leading edge of the overlying plate to surge back, lifting a wall of water producting a tsunami. At convergent boundaries, the tectonic plates are colliding together forming mountains, volcanoes, and earthquakes at divergent boundaries, the tectonic plates are moving away from each other created gaps. Types of plate margins - 1) divergent, 2) convergent and 3) transform take the plate margin tour a plate margin is just the edge of a tectonic plate a continental margin is not the same thing as a plate margin a continental margin is the edge of a continent rather than the edge of a plate.
In plate tectonics, a convergent boundary (also known as a destructive plate boundary) is a result of pressure, friction, and plate material melting in the mantle, earthquakes and volcanoes are common near convergent boundaries. Divergent boundaries occur when two tectonic plates move away from each other convergent boundaries occur when two tectonic plates come together transform plate boundaries occur when two tectonic plates slide past one another. The most common divergent boundaries are the mid-ocean ridges that launched the plate tectonics revolution, and the mid-atlantic ridge is a classic example (see figure 3) shallow earthquakes and minor basaltic lava flows characterize divergent boundaries at mid-ocean ridges. Plate tectonics - convergent boundaries - plates move toward each other at convergent boundaries generally, if two plates are converging, the denser plate will be forced under, or subducted beneath, the less dense one the subducted crust is eventually destroyed the area around converging plates at which subduction occurs is called a subduction zonesubduction occurs when oceanic crust meets.
Convergent boundary 1when two plates move towards each other they are called converging 2convergence of two plate boundaries leads to the folding of land and formation of mountains. Divergent plate boundaries main article: divergent boundary at the mid-oceanic ridges , two tectonic plates diverge from one another as new oceanic crust is formed by the cooling and solidifying of hot molten rock. Divergent boundaries occur when two plates move away from eachother, creating a space between them they are often referred to as constructive plate boundaries because magma flows between the space of the two plates and cools and hardens, creating new crust. At a destructive plate boundary (convergent boundaries) the crust is destroyed as the plates converge or collide an example of this can be found on the west margin of south america a this boundary, convection currents of magma cause the west-moving south american plate to collide with the east-moving nazca plate. • divergent evolution occurs in phylogenetically related organisms, and convergent evolution occurs in organisms, which are not closely phylogenetically related • all the homologous structures bear the same basic plan of the structure whereas the analogous structures are just superficially related.
The main differences are the thickness and nature of the crust in oceanic and continental plates oceanic plates are formed at divergent boundaries mainly at mid ocean ridges the material that is poured out are basaltic lave in nature basalt is denser and heavier than the granite that makes up continental plates oceanic plates are much thinner than the continental plates. Samples from convergent plate margins form at shallower water depths (volcanic arcs) than those from divergent plate margins (mid-ocean ridges), and are therefore characterized by significantly lower temperatures than those from at divergent plate margins.

Plate tectonics plate tectonics theory describes how the lithosphere of the there are three general types of plate boundaries: divergent, convergent, and transform each general type has multiple to compare and establish mid-ocean ridge spreading rates a b c. A divergent plate boundary is a tectonic boundary where two plates are moving away from each other and new crust is forming from magma that rises to the earth's surface between the two plates.
Divergent and convergent plate margins comparison
Most earthquakes at divergent plate boundaries occur at mid-ocean ridges where two pieces of oceanic crust are moving away from each other some earthquakes at divergent boundaries occur in the middle of continents in rift zones. The nazca plate is moving eastwards, towards the south american plate, at about 79mm per year where the two plates meet, the denser oceanic lithosphere of the nazca plate is forced down and under the more buoyant continental lithosphere of the south american plate, descending at an angle into the mantle in a process called subduction. A divergent plate boundary is a weakness in the crust where two plates are moving apart pressure along with the thinness of the crust causes molten material to form and rise to the surface at a subduction zone at certain types of convergent plate boundaries, water entrenched crust partially melts as in dives into the mantle, resulting in rising blobs and intrusions of melted rock into.
Convergent thinking and divergent thinking are two kinds of response by humans to a given problem convergent thinking is a type of response to a problem in which a person deduces information and draws conclusions from the data provided to arrive at a single best answer. Compare and contrast divergent, convergent and transform plate boundaries divergent plate boundaries are where the plates are moving apart from each other convergent plate boundaries are where plates collide. A compare and contrast between convergent & divergent plate boundaries a convergent boundary is colliding there are two kinds of surface features that are associated with a convergent boundary.
Convergent boundaries between continental plates are a bit different than oceanic/oceanic and oceanic/continental mashups continental lithosphere is too buoyant to subduct deeply, so rather than a subduction zone and trench these boundaries encompass a thick mess of folded, piled-up crust. Convergent plate boundaries convergent plate boundaries come in several flavors, but they share one thing in common - plate collisions take a look at the differences between the three examples on this page. At divergent plate margins, black smoke forms immediately on contact of ascending hydrothermal solutions with sea water the black smoke, consisting mainly of black ore (bo) and barite ore (bao), is rapidly dispersed in seawater leaving behind a dominantly yellow ore (yo) at convergent plate.
