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 is convergent boundary short answer?
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 convergent boundary class 9 geography?
Convergent boundaries occur
where two plates slide toward each other to form
either a subduction zone (one plate moving underneath the other) or a continental collision. Continent-to-continent boundaries are regions where two continental convergent plates are colliding leading.
What are the three types of convergent boundary?
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 are the characteristics of convergent boundary?
A convergent boundary, or destructive boundary, is
where two plates are moving towards each other and colliding
. The pressure and friction is great enough at these boundaries that the material in the Earth’s mantle can melt, and both earthquakes and volcanoes happen nearby.
What landforms are created by convergent boundaries?
Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines
are examples of features that can form along plate tectonic boundaries. Volcanoes are one kind of feature that forms along convergent plate boundaries, where two tectonic plates collide and one moves beneath the other.
Which is the best 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 are the three types of plates?
Explanation: There are three types of plate boundaries:
Convergent, Divergent, and Transform/Conservative
. Since you already know about the concepts of plate tectonics, I assume you already know its basic concept: that the Earth’s crust is split into several jigsaw pieces we call as tectonic plates.
Why do Convergent boundaries occur?
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 the difference between a convergent and 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.
What happens when two crusts collide?
At convergent boundaries, where plates push together, crust is either folded or destroyed. When two plates with continental crust collide,
they will crumple and fold the rock between them
. A plate with older, denser oceanic crust will sink beneath another plate. The crust melts in the asthenosphere and is destroyed.
What is a real life example of a divergent boundary?
The mid-Atlantic ridge
lies mostly in the middle of the Atlantic Ocean and is the classic example of a divergent plate boundary. This tells us that a couple of large mantel plumes are at work below the Earth’s surface and these are gradually pulling the crust apart.
What is an example of a convergent?
The Washington-Oregon coastline of the United States
is an example of this type of convergent plate boundary. … 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.
Can convergent boundaries cause volcanoes?
Destructive, or convergent, plate boundaries are where the tectonic plates are moving towards each other. Volcanoes form here in two settings where either oceanic plate descends below another oceanic plate or an oceanic plate descends below a continental plate.
Do convergent boundaries form mountains?
Mountains are usually formed at what are called
convergent plate boundaries
, meaning a boundary at which two plates are moving towards one another. This type of boundary eventually results in a collision.
What are three types of convergent boundaries answers?
There are three types of convergent boundaries:
Oceanic-Continental Convergence
. Oceanic-Oceanic Convergence. Continental-Continental Convergence.
