Scientists have uncovered the geological processes responsible for creating a massive underwater canyon that surpasses the Grand Canyon in scale. The discovery provides new insight into the powerful forces that have shaped the ocean floor over millions of years.

The research team used advanced mapping and geological analysis techniques to trace the canyon's formation, identifying the specific mechanisms — likely a combination of tectonic activity, sediment flows, and underwater erosion — that carved this enormous feature into the seabed. The canyon's sheer size had long puzzled oceanographers and geologists.

The findings contribute to a broader understanding of submarine geology and the dynamic processes that continue to reshape the Earth's ocean basins. The study also highlights how much of the planet's most dramatic landscapes remain hidden beneath the waves, awaiting further exploration.
