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.
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.
Which of the following is something created by convergent plate boundaries?
Deep ocean trenches
What are 3 examples of convergent boundaries?
- Continent‐continent convergence results when two continents collide. ...
- Ocean‐continent convergence occurs when oceanic crust is subducted under continental crust.
What type of zone is created at convergent plate boundaries?
Convergent Plate Boundary Development
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).
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.
What is a real world example of divergent boundary?
Divergent boundaries occur where two plates move apart from each other. This happens at the mid-ocean ridges, where seafloor spreading and volcanic activity continuously add new oceanic crust to the oceanic plates on both sides. Examples are the Mid-Atlantic Ridge and East Pacific Rise .
What are two examples of convergent boundaries?
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.
What are examples of convergent?
Convergent evolution is when different organisms independently evolve similar traits. For example, sharks and dolphins look relatively similar despite being entirely unrelated.
What is a good example of a transform boundary?
The San Andreas Fault and Queen Charlotte Fault are transform plate boundaries developing where the Pacific Plate moves northward past the North American Plate. The San Andreas Fault is just one of several faults that accommodate the transform motion between the Pacific and North American 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.
Where are most convergent plate boundaries found?
Two locations are marked to show this type of plate boundary – the Cascade volcanoes along the Washington-Oregon coast of North America and the Andes mountain range on the western margin of South America.
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. ... 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 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.
Is California a convergent boundary?
The Cascadia Subduction Zone, extending from northern California through western Oregon and Washington to southern British Columbia, is a type of convergent plate boundary . Two parallel mountain ranges have been forming as a result of the Juan de Fuca Plate subducting beneath the edge of North America.
What type of crust is divergent boundary?
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).
