A recent study concluded that there are remains of stone formations. Mountain-likenear Earth’s core, a discovery that sheds light on new details regarding this remote region that lies 1,800 miles beneath our feet.
The study might help explain the origin of mysterious formations near the Earth’s core that have baffled scientists for years, according to the Sky News Arabia report.
Mountains of various heights
• The Earth’s core is likely surrounded by the sunken remains of an ancient sea floor, a discovery that reveals new details regarding this remote region that lies 1,800 miles below our feet, according to the study. The findings might help explain the origin of mysterious conditions near the core that have baffled scientists for years.
• Samantha Hansen, a geophysicist at the University of Alabama, points out that structures can be thought of as mountains of varying heights. And like mountains on Earth, this structure changes over time.”
• The new study suggests that portions of this consolidated material may sink all the way to the outer edge of the core-mantle boundary, where geophysical forces are carving it into a kind of underground mountain range.
• “We knew that such structures exist in the lower mantle,” Hansen said in an email to Motherboard. “However, I think what struck me most was how abundant these formations were. Even with the rigorous criteria we applied to identify robust hits, we found evidence of all over the southern hemisphere.”
years of research
Scientists had researched it for years, but Hansen and her colleagues applied a unique dataset and new seismic testing technique to their research.
• Antarctic observations show that formations at the core-mantle boundary can be relatively thin, extending to only a few miles in some areas, although these areas are very dense.
• Hansen believes that what is known regarding low velocity zones is consistent with being composed of oceanic crust deposited under subduction zones.
• “Our research provides important connections between the shallow and deep Earth structure and the overall processes that drive our planet,” Hansen added.
