When oceanic lithosphere plunges beneath an overriding continental plate, it occurs at a convergent boundary, specifically a subduction zone. This process leads to the formation of features such as deep ocean trenches and volcanic arcs on the continental side. The denser oceanic plate is forced down into the mantle, which can trigger earthquakes and contribute to the geological activity of the region. Subduction zones are key areas for understanding plate tectonics and the recycling of Earth's crust.
Oceanic lithosphere plunges beneath an overriding continental plate at a convergent boundary, specifically at a subduction zone. The denser oceanic plate is forced beneath the less dense continental plate due to tectonic forces, leading to the formation of deep oceanic trenches and volcanic arcs on the overriding plate.
Subduction
At a convergent boundary, typically an oceanic lithosphere collides with either another oceanic lithosphere or continental lithosphere. When an oceanic plate meets a continental plate, the denser oceanic plate subducts beneath the continental plate, leading to the formation of deep ocean trenches and volcanic arcs. If two oceanic plates collide, one may subduct beneath the other, resulting in the creation of island arcs.
The lithosphere sinking into the mantle occurs at a convergent plate boundary, specifically in subduction zones. In these regions, one tectonic plate is forced beneath another, typically an oceanic plate descending beneath a continental plate or another oceanic plate. This process leads to the formation of deep ocean trenches and volcanic arcs. The subduction of the lithosphere is a key driver of tectonic activity and geological phenomena associated with plate interactions.
As odd as it is to think of things this way, continental lithosphere is more buoyant than oceanic lithosphere. The oceanic lithosphere is more dense.

This type of plate boundary is called a convergent boundary or subduction zone. It occurs when two tectonic plates collide, with the denser oceanic plate being forced beneath the less dense continental plate. This process can lead to the formation of deep oceanic trenches and volcanic arcs on the overriding plate.

At an oceanic continental plate boundary, a process called subduction occurs, where the denser oceanic plate is forced beneath the less dense continental plate due to the difference in their densities. This leads to the formation of deep oceanic trenches and volcanic arcs on the overriding continental plate.
The two layers of the lithosphere is made up of the oceanic lithosphere and continental lithosphere. The oceanic lithosphere is associated with oceanic crust and the ocean basins. The continental lithosphere is associated with the continental crust.
When oceanic lithosphere and continental lithosphere collide, the continental lithosphere may be obducted over the oceanic lithosphere or the oceanic lithosphere may be subducted under the continental lithosphere. The latter is thought to be more common. This subduction and obduction generally results in tectonic activity such as volcanoes and earthquakes.
