What exactly is a subduction zone?

A subduction zone is a convergent plate boundary where one tectonic plate, typically an oceanic plate, slides beneath another plate (oceanic or continental) and descends into the Earth's mantle.

What geological features are commonly found at subduction zones?

Characteristic features include deep ocean trenches, volcanic arcs (chains of volcanoes), powerful earthquakes, and the formation of mountain ranges.

Why are subduction zones important for understanding Earth?

They are fundamental to plate tectonics, driving processes like crustal recycling, and are responsible for many natural hazards, including the majority of Earth's largest earthquakes and volcanic eruptions.

Where are some major subduction zones located globally?

Prominent examples include the 'Pacific Ring of Fire', encompassing the Japan Trench, Mariana Trench, Andes Mountains, and the Cascadia Subduction Zone off North America's Pacific Northwest.
