00:00Prepare to uncover a groundbreaking discovery that could reshape Earth's history.
00:04Millions of years ago, a massive underwater collision occurred beneath the Pacific.
00:09Scientists have found remnants of an ancient seafloor,
00:13revealing a tectonic plate that disappeared beneath the Earth's crust millions of years ago.
00:18This research, led by Dr. Jingxuan Wang,
00:21unveils a 12-mile-thick, 1,200-mile-long region in the mantle transition zone.
00:27Why is this significant?
00:29It shows some oceanic slabs slow down and get stuck,
00:32challenging existing tectonic plate theories.
00:35Excitingly, Wang believes many more ancient structures are hidden,
00:39potentially revealing secrets about Earth's and other planets' pasts.
00:44Why does this matter to you?
00:45This discovery may illuminate plate tectonics,
00:48climate change, and the formation of precious minerals.
00:52As the Earth remains full of mysteries,
00:54such discoveries bring us closer to unraveling its ancient story.
