Why 70% of Earth is Still Unmapped? | The Deep Sea Mystery | Jayasim Jayakumar

The deep ocean remains Earth's final frontier, a vast and mysterious realm that is less explored than the surface of Mars or the Moon. While we have mapped the lunar landscape in high resolution, nearly 70% of our own planet's seafloor remains a total mystery. In this deep-dive exploration, we journey through the various layers of the ocean, from the sunlit Epipelagic zone to the crushing pressures of the Hadalpelagic zone, where the Challenger Deep hides secrets 11,000 meters below the waves. We explore why reaching these depths is a feat more difficult than sending astronauts into space, requiring specialized submersibles like those used by James Cameron to withstand pressures that would instantly crush human bone.#jayasimjayakumar #jayasim #oceanexploration #deepsea #marianatrench #seabed2030 #marinelife #sciencefacts #underwaterworld #geography #earthmysteries
