What is a destructive plate boundary simple definition?
A destructive plate boundary is sometimes called a convergent or tensional plate margin. This occurs when oceanic and continental plates move together. The oceanic plate is forced under the lighter continental plate. Friction causes melting of the oceanic plate and may trigger earthquakes.
What is destructive boundary?
Destructive plate boundaries
At a destructive plate boundary (also called convergent boundaries) two plates move towards another. One plate is then pushed underneath the other. (It is the heavier plate that is forced beneath the lighter plate).
What is an example of a destructive plate boundary?
Destructive plate margins occur where an oceanic and continental plate move towards each other. Examples below include the Pacific Plate and Eurasian Plate and the Nazca Plate and the South American Plate.
What are constructive and destructive plate boundaries?
A constructive plate boundary occurs when two plates move away from each other. Find out more about constructive plate margins. A destructive plate boundary occurs when an oceanic plate is forced under (or subducts) a continental plate.
What is the most destructive plate boundary?
Convergent plate boundaries
Convergent plate boundaries
A convergent plate boundary , also known as a destructive plate boundary , usually involves an oceanic plate and a continental plate.
Where are destructive plate boundaries found?
What direction do destructive plates move?
towards one another
Destructive plate margins
The plates move towards one another and this movement can cause earthquakes. As the plates collide, the oceanic plate is forced beneath the continental plate. This is known as subduction . This happens because the oceanic plate is denser (heavier) than the continental plate.
What landforms form at destructive plate boundaries?
As the plates collide, the oceanic plate is forced beneath the continental plate.
…
Landforms associated with destructive plate boundaries.
| Large scale landforms (Destructive plate boundary) | Small scale landforms (Destructive plate boundary) |
|---|---|
| Stratovolcanoes | Cinder cone |
| Caldera volcanoes | |
| Ocean trench | |
| Fold mountains |
What happens at a destructive plate boundary a level?
A destructive plate boundary happens where an oceanic and continental plate move towards each other. The heavier, more dense oceanic plate is forced under the continental plate. As it sinks below the continental plate the oceanic plate melts due to friction in the subduction zone. The crust becomes molten called magma.
What landforms do destructive plate boundaries create?
Landforms associated with destructive plate boundaries

Where are destructive plate boundaries?
Why are earthquakes stronger at destructive plate margins?
At destructive plate margins, oceanic crust subducts beneath continental crust. In this zone of subduction a lot of friction is created as the plates move alongside each other.
What type of volcanoes form at destructive plate boundaries?
Composite volcanoes are found on destructive plate margins , where the oceanic crust sinks beneath the continental crust. Composite volcanoes have the following characteristics: Acidic lava, which is very viscous (sticky).
What can a destructive plate boundary cause?
A destructive plate margin usually involves an oceanic plate and a continental plate. The plates move towards one another and this movement can cause earthquakes. As the plates collide, the oceanic plate is forced beneath the continental plate. This is known as subduction .
What landforms are found at destructive plate margins?
Why do volcanoes occur at destructive plate boundaries?
Destructive plate boundary 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.
