Here's why:
* Subduction: This is the process where one tectonic plate slides beneath another.
* Oceanic Plate: These plates are denser than continental plates.
* Continental Plate: These plates are less dense than oceanic plates.
When these two types of plates collide, the denser oceanic plate is forced beneath the continental plate. This process creates a variety of geological features, including:
* Volcanoes: As the oceanic plate subducts, it melts, generating magma that rises to the surface.
* Trenches: The deepest parts of the ocean occur at the boundary where the plates converge.
* Earthquakes: These are common as the plates grind against each other.
