In plate tectonics, a convergent boundary, also known as a destructive plate boundary, is an actively deforming region where two tectonic plates or fragments of lithosphere
Lithosphere
A lithosphere is the rigid, outermost shell of a terrestrial-type planet or natural satellite that is defined by its rigid mechanical properties. On Earth, it comprises the crust and the portion of the upper mantle that behaves elastically on time scales of thousands of years or greater. The oute…
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 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 can happen at a convergent boundary?
Convergent boundaries are highly unstable areas of the lithosphere of the Earth. 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 a good sentence about convergent boundary?
The tectonics underlying the Sunda arc are a type of plate boundary known as a convergent boundary. Japan's dealing with a single convergent boundary, but San Francisco is staring down multiple faults, and the ones that matter are transform faults.
What is convergent boundary class 9 geography?
(ii) Convergent boundary : Boundary where plates collide with each other, causing one plate slide below the other plate.
What do you mean by divergent boundary?
Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.
What is a convergent boundary and give an example?
Examples of continent-continent convergent boundaries are the collision of the India Plate with the Eurasian Plate, creating the Himalaya Mountains, and the collision of the African Plate with the Eurasian Plate, creating the series of ranges extending from the Alps in Europe to the Zagros Mountains in Iran.
Where is the convergent boundary?
Lesson Summary. Convergent boundaries occur when two plates move towards each other. The two main types of tectonic plates are oceanic and continental. Oceanic plates are denser due to being made from basalt rock and thus will sink, or subduct, under continental plates, which are made of granitic rocks.
Where are divergent boundaries?
Divergent boundaries are spreading boundaries, where new oceanic crust is created to fill in the space as the plates move apart. Most divergent boundaries are located along mid-ocean oceanic ridges (although some are on land).
What are 3 examples of convergent boundaries?
Three types of convergent boundaries are recognized: continent‐continent, ocean‐continent, and ocean‐ocean.
Which is an example of a convergent plate boundary?
The Pacific Ring of Fire is an example of a convergent plate boundary. At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents.
What is convergent in science?
Convergent (Colliding): This occurs when plates move towards each other and collide. When a continental plate meets an oceanic plate, the thinner, denser, and more flexible oceanic plate sinks beneath the thicker, more rigid continental plate. This is called subduction.
What is an example of a convergent?
Birds and Bats All bats and birds "converged" on the ability of flight in response to environmental stimuli and biological goals. However, the arm bones in both birds and bats are structurally the same and considered homologous. The wing shape, however, is what is convergent.
What is divergent in science?
[ dĭ-vûr′jənt ] 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.
What is the difference between divergent and convergent plate boundaries?
Convergent boundary is formed when plates come towards each other whereas divergent boundary is formed when plates move away from each other.
What is the definition of divergent in science?
Divergent (Spreading):This is where two plates move away from each other. Molten rock from the mantle erupts along the opening, forming new crust.
What are 2 examples of divergent boundaries?

What is a sentence for divergent boundary?
Globally most fault zones are located on divergent plate boundaries on oceanic crust. This example is from Wikipedia and may be reused under a CC BY-SA license. Most divergent plate boundaries are at the bottom of the oceans; therefore, most volcanic activity is submarine, forming new seafloor.
What is the description of divergent?
Definition of divergent 1a : moving or extending in different directions from a common point : diverging from each other divergent paths — see also divergent evolution. b : differing from each other or from a standard the divergent interests of capital and labor.
What is a Convergent Boundary?
Imagine the world is like an egg, with a shell that is cracked all over. Just like these cracked pieces of eggshell, the entire outer crust of the Earth is broken down into sections, called tectonic plates. But instead of resting on liquid-y egg yolk, these plates float on a sea of hot magma, something you'd only actually see in rare events like volcanoes. This magma is not a liquid - it's actually solid, but under the incredible pressures beneath the Earth's crust, even solids flow like honey.
What are some examples of convergent boundaries?
Examples of Convergent Boundaries. The West Coast of South America is a convergent boundary between the Na zca Plate and the South American Plate. The collision of this oceanic and continental plate was how the Andes Mountains were formed. Convergent boundaries can also form islands.
What happens when one continental plate and one oceanic plate collide?
When one oceanic and one continental plate collide, the denser oceanic plate subducts beneath the continental plate. In this case, an underwater trench can form on the oceanic side, and volcanoes and mountains can form on the continental side. Convergent boundaries are where the tectonic plates meet.
What is the term for the boundaries between the plates that are moving towards each other and colliding?
The Earth's crust is split, like an eggshell, into many sections called tectonic plates. Convergent boundaries are the borders between the plates that are moving towards each other and colliding.
What happens when two continental plates collide?
When two continental plates collide, the impact is so significant that the material in the subduction zone is pushed upwards. This is how mountain ranges form, including even the biggest ones in the world, like the Himalayas.
When one oceanic and one continental plate meet, what happens?
When one oceanic and one continental plate meet, the denser oceanic plate subducts under the less dense continental plate. This forms a trench on the oceanic side, and volcanoes and mountains on the continental side.
What happens when two plates meet?
When two plates meet, one inevitably gives way and sinks below the other. This is called subduction. The subduction zone is the area where two plates are sandwiched on top of each other, like a tectonic BLT. Exactly what happens during subduction depends on the type of tectonic plates involved.
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 ...
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, ...
Do convergent boundaries cause earthquakes?
Earthquakes are common any time large slabs of Earth come into contact with each other, and convergent boundaries are no exception. In fact, most of the Earth's most powerful quakes have occurred at or near these boundaries.
