12/16/2023 1 Comment Divergent boundary examples![]() This is the most famous boundary because it’s the most active seismic area in the world. Here are 5 convergent boundary examples in real life. Mountain ranges can also form as well as earthquake action. Typically, no subduction takes place as both plates are less dense than the mantle.Īs a result of this boundary, intense faulting and folding can occur. It occurs when two continental plates collide with each other. This type of boundary is not as well understood as the others. The effects of this boundary are the formation of an oceanic trench and an area where earthquakes occur with increasing depth.Ĭhains of volcanic islands are also formed. The sunken plate gets heated in the mantle causing it to melt. So, it is pushed down or subducted beneath the other plate which is warmer and younger. Out of the two, the older or colder plate will be denser. e.g., a lithospheric mantle and an oceanic crust. Two oceanic plates meet under the ocean crust. Ocean trenches can also form as well as volcanic eruptions. The effect of this boundary is that an area of earthquake action is formed. For example, depths of about 160 m can cause the material to reach melting temperatures. Since the oceanic plate is denser than the continental plate, it is pushed or subducted under the continental plate.Īs the oceanic plate gets pushed into the mantle, it reaches high-temperature areas. This is where an oceanic and a continental plate collide. These are determined by the area or location on the earth’s crust where the boundaries are formed. Types of Convergent BoundariesĬonvergent boundaries are of 3 types. ![]() The others are divergent and transform boundaries that are created in a different way. This is a high activity area that can also literally get too hot to touch!Ī convergent boundary marks the area where two tectonic plates collide or meet each other.Īs a result of this, dramatic seismic events can follow like earthquakes, volcanic eruptions, or deformation of the crust.Ĭonvergent boundaries are just one of three types of tectonic plate boundaries that can form. You are likely to get some from a convergent boundary. Volcanic activity sometimes occurs within the rift.Want a front-row seat to some tension-packed seismic action on earth? Two locations are marked within the rift valley of East Africa, and another location is marked within the Red Sea.Įffects that are found at this type of plate boundary include: a rift valley sometimes occupied by long linear lakes or a shallow arm of the ocean numerous normal faults bounding a central rift valley shallow earthquake activity along the normal faults. Visit the Interactive Plate Boundary Map to explore satellite images of divergent boundaries between continental plates. There the plates have fully separated, and the central rift valley has dropped below sea level. The Red Sea is an example of a more completely developed rift. The plate has not been completely rifted, and the rift valley is still above sea level but occupied by lakes at several locations. The East Africa Rift is in a very early stage of development. The East Africa Rift Valley is a classic example of this type of plate boundary. Two locations are marked: 1) the Mid-Atlantic Ridge exposed above sea level on the island of Iceland, and 2) the Mid-Atlantic Ridge between North America and Africa.Įffects that are found at a divergent boundary between oceanic plates include: a submarine mountain range such as the Mid-Atlantic Ridge volcanic activity in the form of fissure eruptions shallow earthquake activity creation of new seafloor and a widening ocean basin. Visit the Interactive Plate Boundary Map to explore satellite images of divergent boundaries between oceanic plates. When the next eruption occurs, the fissure most likely develops down the center of the cooling magma plug with half of the newly solidified material being attached to the end of each plate. ![]() Instead, it fills the fissure and solidifies. A frequent misconception is that the Ridge is a build-up of volcanic materials however, the magma that fills the fissure does not flood extensively over the ocean floor and stack up to form a topographic high. The Ridge is a high area compared to the surrounding seafloor because of the lift from the convection current below. The Mid-Atlantic Ridge is a classic example of this type of plate boundary.
