The collision of plates commonly includes "subduction", where one plate is forced under the other, down into the mantle. These plates are melted and rise again, adding to the magma under the overlying plate. This creates heated rock that can later emerge through the surface in volcanoes.
Oceanic plates are thinner and denser than continental plates, so are the ones forced down, either under a continental plate or another oceanic plate.
Subduction (I believe that's what you meant) occurs at CONVERGENT boundaries, where two plates collide and the less dense one remains and the denser one sinks. An example of subduction is two oceanic plates colliding. Oceanic plates contain mainly basalt, which is dense. The oceanic plate closer to a heat source (hot spot, volcano) would remain in place while the denser plate sinks (cold water is denser than hot water so it sinks) below the other. When an oceanic plate and a continental plate collide, the oceanic plate sinks because granite (what continental plates are composed of mainly) is less dense than basalt, therefore the oceanic plate would sink. However, when two continental plates collide, because both plates are made of granite and are not very dense, they push and shape the land into mountains.
when oceanic crust and continental crust collide, the oceanic crust sinks down beneath the continental crust. this is called subduction.
The volcanic eruptions are the cause of tectonic movement of the "plates" meaning that when the plates hit each other they cause the magma under the earth to rise and sometimes erupt causing ash and sometimes lava to leave the volcanic shell in an eruption
When an oceanic plate subducts into the Earth's hot interior, it sinks beneath a continental or another oceanic plate, leading to the formation of a trench. As the plate descends, it heats up and releases water and other volatiles, which can trigger melting in the overlying mantle. This process often results in volcanic activity and the creation of magma, contributing to the formation of volcanic arcs. Additionally, this subduction can lead to earthquakes due to the intense pressure and friction between the plates.
Volcanoes tend to form at convergent tectonic plate boundaries where subduction is occurring (such as the western coast of South America) and at divergent plate boundaries where two tectonic plates are moving apart (e.g. the Mid-Atlantic-Ridge and Iceland). Earthquakes also occur at convergent boundaries and in fact these tend to cause the strongest earthquakes. Earthquakes also occur at transform boundaries (such as the San Andreas fault) however these do not tend to cause the formation of volcanoes. So to find volcanoes and large earthquakes you should be looking at convergent plate boundaries where subduction is occurring.

No, the denser plate sinks under the less dense plate in a process called subduction.
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.

When tectonic plates of different densities collide, the denser plate typically subducts, or sinks, beneath the lighter plate. This process can lead to the formation of deep ocean trenches and volcanic activity as the subducted plate melts and releases magma. The collision may also result in the uplift of mountain ranges and the creation of earthquakes due to the intense stress and friction at the plate boundary.
A convergent boundary is formed when plates collide. At this type of boundary, the denser plate sinks beneath the less dense plate in a process known as subduction. This collision often results in the formation of mountain ranges, volcanoes, and deep ocean trenches.
It is called subduction. When subduction occurs one plate slips beneath the other and sinks into the Earth's mantle and creates a trench.
When tectonic plates of different densities collide, the denser plate typically subducts or sinks beneath the less dense plate. This process can lead to the formation of deep ocean trenches and volcanic arcs. The subduction zone can also generate significant geological activity, including earthquakes and the creation of mountain ranges. Over time, the interaction between the plates can lead to the recycling of materials into the Earth's mantle.
This happens at a plate boundary. The oceanic plate subducts (sinks) under the continental plate, because it is heavier. (the oceanic plate is made of basalt and the continental plate is made of granite.) This happens at a destructive plate margin. it is called this because part if the oceanic plate is destroyed, because it melts as it sinks.
is forced below the less dense continental plate in a process called subduction. This can lead to the formation of deep ocean trenches, volcanic arcs, and earthquakes along the subduction zone.
