It’s something about the history of the Earth that interests me a lot. How did we get to this point in time? Is a question I ponder over frequently. It’s mysterious, yet through science and new technology we may be able to have all the answers we’ve been searching for.
Our Earth is over 4 billion years old. New research has found something interesting about how continents were formed. During the first billion years, giant meteorite impacts on the Earth created the continents according to Curtin University. Apparently, this has been a theory that’s been around for decades, although it’s only recently been confirmed.
Dr. Tim Johnson is the one to discover the new information regarding the formation of continents from meteor showers. He says “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, we found evidence of these giant meteorite impacts”. With this new information, the dinosaur extinction from meteors is that much more plausible! The meteor showers allegedly happened consistently, which caused these huge land masses. There’s question of if this will ever happen again, and the answer is: maybe. Although, it’s a very slim chance, as the last time this happened was billions of years ago.
