Study.. the discovery of “mountains” near the Earth’s core

A recent study has found remnants of rocky, mountain-like formations near Earth’s core, a discovery that sheds light on new details about this remote region 1,800 miles below our feet.

The study could help explain the origin of mysterious formations near Earth’s core that have baffled scientists for years.

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 about this remote region that lies 1,800 miles below our feet, according to the study. The findings could 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 the 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 coalesced 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 such structures existed in the lower, 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 these formations at the core-mantle boundary can be relatively thin, extending only a few miles in some areas, although these areas are very dense.
• Hansen believes that what is known about the low-velocity zones is consistent with the fact that they are made up of ocean crust deposited beneath subduction zones.
• “Our research provides important links between shallow and deep Earth structure and the overall processes that drive our planet,” Hansen added.
