When two oceanic plates collide, the older, denser plate subducts beneath the younger, less dense plate.
This type of interaction occurs at an Oceanic-Oceanic convergent plate boundary, where subduction creates significant geological features.
As the older plate subducts, intense heat and pressure cause it to melt partially. This process, known as magma generation, produces molten rock that rises through the overlying oceanic crust, forming a volcanic island arc. The continuous movement and interaction of the plates result in frequent earthquakes.
A deep ocean trench forms at the subduction zone, where a subduction plate is drawn into the mantle.
The Mariana Trench is a famous example of subduction, where the Pacific plate subducts beneath the Philippine plate, forming the deepest ocean trench on Earth.
Another example of this is the Aleutian Islands, where the Pacific plate subducts beneath the oceanic extension of the North American plate.
Many of these islands remain volcanically active, and airplanes sometimes avoid flying over the region to reduce the risk of being caught in an eruption.

The Earth's surface is made of large, moving sections called tectonic plates. Sometimes, two oceanic plates slo…
