What happens in a subduction zone?
In a subduction zone, one tectonic plate is forced beneath another plate into the Earth's mantle. This process leads to the formation of deep ocean trenches, earthquakes, and volcanic activity. Subduction zones are also associated with the creation of mountain ranges and volcanic arcs.
What happens after subduction?
After subduction, the denser oceanic plate sinks into the mantle where it undergoes partial melting. This molten material can then rise to the surface through volcanic eruptions, creating volcanic arcs and contributing to the formation of new crust. The process of subduction helps recycle materials in the Earth's crust and plays a key role in plate tectonics.
What happens during subduction?
Dense oceanic crust slides under less dense continental crust
What is the difference between spreading and subduction?
Spreading occurs when two tectonic plates move away from each other, creating new oceanic crust at mid-ocean ridges. Subduction, on the other hand, happens when one tectonic plate is forced beneath another plate into the mantle. Subduction zones are typically associated with deep ocean trenches and volcanic activity.
What happens at a trench?
At a trench, tectonic plates are actively moving apart, leading to the creation of new crust. This process, known as seafloor spreading, can also involve the subduction of one tectonic plate beneath another. Trenches are typically sites where deep oceanic trenches are formed and earthquakes and volcanic activity can occur.
What happens during a convergent boundary and what usually forms?
At a convergence boundary during collision of two plates there could either be Subduction or Outcropping. Subduction occurs when the collision involves plates of different types and densities while the other happens when it involves similar plate types. Mountain ranges are formed, also Subduction Zones gives rise to Trenches.
Explain the relationship between trenches and seafloor spreading?
1. New sea-floor is created by the upwelling of magma at mid-ocean spreading centers; old ocean floor is destroyed by subduction at deep sea trenches. 2. The area is a subduction zone. Magma from underground comes up and destroys that crust. That crust is then recycled and the magma cools and hardens. That creates new land, that creates the trenches. Seafloor spreading is in the ocean and happens with convection currents. That is the relationship between. 3. As new seafloor is formed at mid-ocean ridges, the old seafloor is pushed down into trenches at subduction zones.

What does it mean when plates have subduction on each other?
When plates have subduction, it means that one tectonic plate is being forced beneath another plate. This process happens at convergent plate boundaries where two plates collide, and the denser plate sinks into the mantle. Subduction can lead to the formation of deep ocean trenches, volcanic arcs, and earthquakes.
What happens in an ocean trench?
Subduction
What happens at colliding boundries?
subduction happens and mountains and volcanoes form
What happens at deep-ocean trenches?
subdution
what happens to a convergent boundary?
a subduction zone forms
What is it called when two plates slide one under the other?
It is known as subduction.
What happens when a tectonic plate gets subduction?
they will form a mountain
What happens to the ocean floor at the deep ocean trenches?
what happens is the ocean floor does not just keep spreading.instead, it sinks beneath deep underwater canyons called deep- ocean trenches
