Subduction is a geological process in which one tectonic plate moves under another tectonic plate and sinks into the mantle. This process is associated with several geological phenomena and features. Subduction zones are typically found at convergent plate boundaries, where two plates collide. The subducting plate, which is usually denser and older, descends into the mantle, while the overriding plate, which is usually younger and less dense, remains at the surface.

Subduction is associated with the formation of various geological features. Volcanic arcs are common along subduction zones, as the subducting plate melts and releases fluids that rise through the overriding plate, leading to volcanic activity. Earthquakes are also frequent in subduction zones, often occurring as the subducting plate bends and breaks. Subduction zones can also lead to the formation of deep-sea trenches, which are long, narrow depressions in the ocean floor.

The process of subduction plays a crucial role in the recycling of Earth's crust. As the subducting plate descends into the mantle, it carries with it sediments, oceanic crust, and mantle material. This material is then melted and recycled into the mantle, contributing to the formation of new crust at mid-ocean ridges. Subduction is also associated with the formation of mountain ranges, as the overriding plate is uplifted and deformed.

Subduction is a dynamic and ongoing process that shapes the Earth's surface and interior. It is responsible for the formation of many of the planet's most iconic geological features and plays a vital role in the recycling of Earth's crust. Understanding subduction is essential for comprehending the Earth's geological history and the processes that drive plate tectonics.
