Continental crust is too buoyant to subduct. When two continental plates converge, they smash together
and create mountains
. The amazing Himalaya Mountains
What are the two types of convergent plate boundaries?
When two tectonic plates move toward each other and collide, they form a convergent plate boundary. 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 plates involved.
What type of plate boundaries are there where continents are coming together?
Continent-
Continent Convergent Plate Boundaries
.
Which is the best example of a convergent plate boundary?
Answer:
The Washington-Oregon coastline of the United States
is an example of this type of convergent plate boundary. Here the Juan de Fuca oceanic plate is subducting beneath the westward-moving North American continental plate. The Cascade Mountain Range is a line of volcanoes above the melting oceanic plate.
What are three types of convergent boundaries answers?
There are three types of convergent boundaries:
Oceanic-Continental Convergence
. Oceanic-Oceanic Convergence. Continental-Continental Convergence.
Do 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.
How many tectonic plates are there?
how many tectonic plates are there? There are major, minor and micro tectonic plates. There are
seven major plates
: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American.
What causes the plates to move?
The heat from radioactive processes within the planet’s interior
causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift.
What are examples of convergent boundaries?
Examples. The
collision between the Eurasian Plate and the Indian Plate that is forming the Himalayas
. Subduction of the northern part of the Pacific Plate and the NW North American Plate that is forming the Aleutian Islands. Subduction of the Nazca Plate beneath the South American Plate to form the Andes.
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.
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.
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.
What are the examples of the three main types of convergent plates?
- Continent‐continent convergence results when two continents collide. …
- Ocean‐continent convergence occurs when oceanic crust is subducted under continental crust.
What are three boundary types?
- Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust. …
- Divergent boundaries – where two plates are moving apart. …
- Transform boundaries – where plates slide passed each other.
Do convergent boundaries cause mountains?
Mountains are usually
formed
at what are called convergent plate boundaries, meaning a boundary at which two plates are moving towards one another. … Sometimes, the two tectonic plates press up against each other, causing the land to lift into mountainous forms as the plates continue to collide.
What happens when convergent boundaries occur?
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. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
