ORIGIN OF CONTINENTS

Aug. 13, 2022

A new Curtin University study has found the most robust evidence yet showing that Earth’s continents were formed by giant meteorite impacts.

About:

The paper, ‘Giant impacts and the origin and evolution of continents’, was published in Nature on August 10.
By examining tiny crystals of the mineral zircon in rocks from the Pilbara Craton in Western Australia, which represents Earth’s best-preserved remnant of ancient crust, experts found evidence of these giant meteorite impacts.
These impacts were prevalent during the first billion years or so of the planet’s history.
