Our planet was born around 4.5 billion years ago. To understand this mind-bendingly long history, we need to study rocks and the minerals they are made of. In a new study, evidence of rocks of a similar age were found in Australia.
On the scale of cataclysmic events, the whomping impact of a Mars-sized object that crashed into Earth some 4.5 billion years ago ranks pretty highly: thought to have set in motion the movement of our planet's fractured, rocky crust.
Many southwestern parts of the United States have been spotted with giant cracks or fissures in the ground. As per reports, these fissures have occurred due to harnessing groundwater indiscriminately over the years.
Recently Australian researchers found the first ever evidence of a plutonium radioactive isotope in the Earth's crust that originally came from outer space, namely a supernova.
