“The impact would have triggered earthquakes orders of magnitude greater than terrestrial earthquakes, it would have caused huge tsunamis and would have made cliffs crumble,” “Material from the impact would have spread worldwide. These spherules were found in sea floor sediments that date from 3.46 billion years ago.”As of this writing, the asteroid is second to the oldest discovered to have hit our Earth and also one of the biggest. Dr. Glikson added that the asteroid must be 15 miles across and should have left a crater that is at least a hundred miles wide. Where exactly did this asteroid strike the earth is still remained to be solved. The crater left by the asteroid in question could have been easily disfigured by volcanoes and tectonic plate movements. The head scientist adds, “Any craters from this time on Earth’s surface have been obliterated by volcanic activity and tectonic movements.” There may have been any of these impacts of the same nature but still evidences haven’t been unveiled. To wrap up, Dr. Glikson expressed:
“This is just the tip of the iceberg. We’ve only found evidence for 17 impacts older than 2.5 billion years, but there could have been hundreds.” “Asteroid strikes this big result in major tectonic shifts and extensive magma flows. They could have significantly affected the way the Earth evolved.”
