A new style of details supports the idea that continents Land shaped when a big meteor collided with our planet in the past.
The best proof of how Earth’s continents very first fashioned has been found by researchers, and this is constant with extended-held beliefs.

At present, the seven continents that make up Land it constitutes considerably less than 30% of the planet’s land mass, while the remaining 70% is produced up of drinking water. The geography and terrain that exists on this earth is a consequence of the tectonic exercise of the plates and crust around hundreds of thousands of decades, which has been the lead to of regional evolution.
“We uncovered proof of this substantial meteor impression by inspecting microscopic crystals of the mineral zircon in Western Australia’s Pilbara Craton rocks, which mirror the most effective remnants of the outdated earth’s crust,” explained Tim Johnson, Curtin University geologist and lead author. of the studio. , quoted by chewable.
“Our conclusions recommend that the mechanism that finally gave rise to the continents started out with substantial meteorites that hit billions of decades in advance of nearly anything that killed the dinosaurs,” he added.
Having said that, additional analysis is required to study it. Johnson and his group plan to proceed on the lookout at the old rock in an region similar to the Pilbara craton to see if these results suit across the planet. Land.
