What is a real life example of a convergent boundary?
The Himalayas are an example of convergent boundaries. The Andes mountains formed at the convergence of the Nazca Plate and the South American Plate. The Nazca Plate is less dense than the South American Plate and subducts underneath.
What are the 4 types of convergent boundaries?
Convergent boundaries , where two plates are moving toward each other, are of three types, depending on the type of crust present on either side of the boundary — oceanic or continental . The types are ocean-ocean, ocean-continent, and continent-continent.
What landforms are formed at a convergent boundary?
convergent boundaries form strong earthquakes and they also form volcanic mountains or islands In a subduction zone, the subducting plate, which is normally a plate with oceanic crust, moves beneath the other plate, which can be made of either oceanic or continental crust.
What can be formed at a convergent boundary?
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. Convergent boundaries form strong earthquakes, as well as volcanic mountains or islands, when the sinking oceanic plate melts.

What are 3 things that are formed at a convergent boundary?
A convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction). The collision of tectonic plates can result in earthquakes, volcanoes, the formation of mountains, and other geological events.
What types of things happen at convergent boundaries?
A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone.
What is formed at a convergent boundary with subduction?
An accretionary wedge forms between the converging plates as material is scraped off the subducting plate. A forearc basin develops in the low area between the two mountain ranges.
What is formed at divergent plate boundaries?
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.
What are 3 facts about convergent boundaries?
Subduction Zones are convergent boundaries The plates form a subduction zone with one plate descending beneath the other plate. Two ocean plates converge forming a subduction zone also. Two continental plates colliding form a collision zone. The two continental plates instead form mountain ranges like the Himalayas.
What do convergent plates cause?
Oceanic-Oceanic Convergent Boundary 4. At a convergent boundary between two plates of oceanic lithosphere, the older, denser oceanic plate will always subduct, which will cause earthquakes and form volcanic isles.
What 3 activities occur along plate boundaries?
For example, sections of Earth's crust can come together and collide (a “convergent” plate boundary), spread apart (a “divergent” plate boundary), or slide past one another (a “transform” plate boundary).
What type of earthquakes occur at convergent boundaries?
Deep, large magnitude earthquakes commonly occur at convergent plate boundaries. Earthquakes at convergent plate boundaries are distributed with predictable locations and depths.
Convergent Plate Boundaries - Geology (U.S. National Park Service)
Subduction. Where tectonic plates converge, the one with thin oceanic crust subducts beneath the one capped by thick continental crust. A subduction zone consists of material scraped off the ocean floor near the coast (accretionary wedge) and a chain of volcanoes farther inland (volcanic arc).
What is convergent boundary?
A convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction). The collision of tectonic plates can result in earthquakes, volcanoes, the formation of mountains, and other geological events.
What are the three types of convergent plate boundaries?
• There are three types of convergent plate boundaries: oceanic-oceanic boundaries, oceanic-continental boundaries, and continental-continental boundaries. Each one is unique because of the density of the ...
What happens when two oceanic plates collide?
When two oceanic plates collide, the denser plate sinks below the lighter plate and eventually forms dark, heavy, basaltic volcanic islands. The western half of the Pacific Ring of Fire is full of these volcanic island arcs, including the Aleutian, Japanese, Ryukyu, Philippine, Mariana, Solomon, and Tonga-Kermadec.
Why are continental plates unique?
Each one is unique because of the density of the plates involved. • Convergent plate boundaries are often the sites of earthquakes, volcanoes, and other significant geological activity. Earth's surface is made up of two types of lithospheric plates: continental and oceanic. The crust that makes up continental plates is thicker yet less dense ...
What are oceanic plates made of?
Oceanic plates are made up of heavier basalt, the result of magma flows from mid-ocean ridges . When plates converge, they do so in one of three settings: oceanic plates collide with each other (forming oceanic-oceanic boundaries), oceanic plates collide with continental plates (forming oceanic-continental boundaries), ...
Why do tectonic plates move?
Because of thermal changes in the mantle, tectonic plates are always moving—through the fastest-moving plate, the Nazca, only travels about 160 millimeters per year. Where plates meet, they form a variety of different boundaries depending on the direction of their motion. Transform boundaries, for example, are formed where two plates grind ...
Where are divergent boundaries formed?
Divergent boundaries are formed where two plates pull apart from each other (the most famous example is the Mid-Atlantic Ridge, where the North American and Eurasian plates diverge). Convergent boundaries are formed wherever two plates move toward each other. In the collision, the denser plate is typically subducted, ...
What Happens At A Convergent Boundary?
Some or all of these activities happen at the convergent boundaries: subduction of the denser plate underneath the less dense one , melting of parts of the subducted plates, plate collision, faulting and folding, crustal deformation, magma generation, volcanic eruptions, and earthquakes.
What is the name of the mountain range formed by a convergent plate boundary?
Fold mountain ranges form at convergent plate boundaries. When tectonic movements cause two tectonic plates to approach each other at the convergent plate boundary, deposits of sedimentary and metamorphic rocks at such boundaries often crumple and fold to form mountains called fold mountains. The presence of mechanically vulnerable layers like a layer of salt in such deposits speeds up the process of folding.
What happens to the tectonic plates at the subduction zone?
At the subduction zone of a convergent boundary, the denser tectonic plate slides underneath the relatively less dense plate. As the plate slides to greater depths of about 100 km below the surface of the Earth, it comes into contact with the relatively hotter environment of the mantle. As the fluids are released from the subducting plate into the hot mantle below, the process of partial melting of the parts of the subducted plate and the sediments carried by it begins to take place. Thus, a viscous and hot liquid called magma is generated which then moves up through the vent between the two sliding tectonic plates.
What happens when two plates collide?
Since two continental plates are colliding, subduction becomes questionable as the difference in density between the plates is usually quite low. Instead, subduction might happen to some extent if the heavier lithosphere below the crust might break free from it due to the forces of friction and pressure created at the convergent boundary. Such types of convergent boundaries are also subjected to extensive faulting and folding of the rocks within the two plates that are colliding with each other.
What happens to magma when it melts?
The magma thus ascends through the crack between the two plates, melting and fracturing the plates as it moves upwards.
How were fold mountains formed?
These mountains were formed as a result of the collision between the Eurasian Plate and the Indo-Australian Plate at the convergent boundary. The Andaman and Nicobar Islands located in the Indian Ocean and part of the territory of India were also formed in a similar manner.
Where are volcanoes formed?
Volcanoes are formed at three locations on the crust of the Earth: at convergent boundaries, divergent boundaries, and hot spots. When two tectonic plates approach each other, ...
