A new study has found a missing part of Earth’s crust that was not included in records before. Scientists used images from space to look at water marks and missing earth layers, paying attention to something called The Great Unconformity at the Grand Canyon.
Scientists explained that the missing Earth crust is because of glacial erosion, which they are still figuring out.
More study shows that glacial erosion during a time called Snowball Earth (a period when Earth was almost or completely covered in ice) took away between three and five kilometers of rock. The study’s writers later found special marks in crystals that showed a lot of changes in Earth’s surface and material moving before the Phanerozoic era (a geologic time zone known for the rise and development of visible life), which suggests that the missing pieces ended up in the sea.
Glacial activity removed roughly one billion cubic kilometers of crust, says Dr. Brenhin Keller
More information shows that similar missing parts appear all over the world, changing what we know about Earth’s very old history. This discovery challenges old ideas by showing how big a role glacial erosion played in wearing away large parts of the Earth’s crust, changing how people see geology. Experts say more different kinds of studies are needed to understand it all better.
Conclusion
Recap of Key Points: Scientists recently discovered a missing part of Earth’s crust using images from space. This was linked to glacial erosion during a time called Snowball Earth, which may have changed how we understand geology!
Final Thoughts: Earth’s past is full of surprises! Who knew glaciers could take away so much rock—like a giant geological cleanup!
