Where are convergent boundary located?
Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere. The geologic features related to convergent boundaries vary depending on crust types. Plate tectonics is driven by convection cells in the mantle.
Where are plate boundaries located?
Plate boundaries. Plate boundaries are found at the edge of the lithospheric plates and are of three types, convergent, divergent and conservative. Wide zones of deformation are usually characteristic of plate boundaries because of the interaction between two plates.
Where on earth can you find convergent boundaries subduction?
The Cascade Mountain Range is a line of volcanoes above the melting oceanic plate. The Andes Mountain Range of western South America is another example of a convergent boundary between an oceanic and continental plate. Here the Nazca Plate is subducting beneath the South American plate.
How subduction occur in convergent plate boundaries?
Subduction is a geological process in which the oceanic lithosphere is recycled into the Earth’s mantle at convergent boundaries. Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the second plate and sinks into the mantle.
What is Map of plate boundaries?
A map of the tectonic plates of the earth showing the different boundary types in different colors. Locations where plates collide (convergent boundaries) are shown in red. Locations where plates are spreading (divergent boundaries) are shown in yellow.
Why are volcanoes mostly found at places where Continents meet the seas?
This is because the Earth’s crust is broken into a series of slabs known as tectonic plates. Although most of the active volcanoes we see on land occur where plates collide, the greatest number of the Earth’s volcanoes are hidden from view, occurring on the ocean floor along spreading ridges.
What is the direction of the convergent plate boundaries?
convergent plate boundary. A tectonic boundary where two plates are moving toward each other. If the two plates are of equal density, they usually push up against each other, forming a mountain chain. If they are of unequal density, one plate usually sinks beneath the other in a subduction zone.
What are 2 examples of subduction zones?
An oceanic plate can descend beneath another oceanic plate – Japan, Indonesia, and the Aleutian Islands are examples of this type of subduction. Alternately, an oceanic plate can descend beneath a continental plate – South America, Central America, and the Cascade Volcanoes are an example of this type of subduction.
Where does the process of subduction occur?
Subduction is a kind of geological recycling that occurs at convergent plate boundaries, where two tectonic plates come together due to the motion of the fluid mantle layer of the earth.
