What Happened in Brief. According to abundant geological evidence, an asteroid roughly 10 km (6 miles) across hit Earth about 65 million years ago. This impact made a huge explosion and a crater about 180 km (roughly 110 miles) across. Debris from the explosion was thrown into the atmosphere, severely altering the climate, and leading to the. Since the formation of the moon, Earth’s spin has been slowing down by about 3.8 mph every 10 million years, mostly due to the moon’s gravitational pull on our planet. So it’s a lot more likely that Earth’s spin will continue to slow down in the future, not speed up. Mar 05, 2018 · Around 439 million years ago, 86% of life on Earth was wiped out. Scientists believe two major events resulted in this extinction: glaciation and falling sea levels. Some theories suggest that the Earth was covered in such a vast quantity of plants that they removed too much carbon dioxide from the air which drastically reduced the temperature.
