Sixty-six million years ago, 70 percent of all species on land and in the seas, including the dinosaurs, suddenly went extinct, in the disastrous aftermath of the collision of a large asteroid or A major impact event releases the energy of several million nuclear weapons detonating simultaneously when an asteroid of only a few kilometers in diameter collides with a larger body such as the Earth (image: artist's impression). An impact event is a collision between astronomical objects causing measurable effects. [1] Apophis is an asteroid about 270 meters across (almost three football fields). In 2029 it will pass very close to the Earth: within the orbits of our communication satellites. It won't hit; however there is a slight chance that this close pass will shift its orbit exactly the right amount to cause it to hit Earth on a second pass in 2036. Becker's team had previously found such gas-bearing buckyballs in rock layers associated with two known impact events: the 65 million-year-old Cretaceous-Tertiary impact and the 1.8 billion-year-old Sudbury impact crater in Ontario, Canada. They also found fullerenes containing similar gases in some meteorites. A growing body of geological evidence is suggesting that the dinosaurs were already enduring climatic chaos before the asteroid, thanks to huge, relentless volcanism in India’s Deccan Traps. For The asteroid, after the impact of which Chicxulub appeared, flew to our planet 65 million years ago. It is possible that the dinosaurs became extinct precisely after the fall of the Yucatan meteorite. The power of the explosion was so great that it led to the formation of a tsunami and provoked tectonic and volcanic activity throughout the Earth. An impact crater approximately 45km in diameter is created in modern-day Montagnais, Nova Scotia, Canada. [523.185] 35 million BCE. An asteroid about 7-10km in diameter impacts the Earth in modern-day Popigai, Siberia, Russia, leaving an impact crater 80-100km in diameter, 10km deep. [523.185] [526.xviii,165] 35 million BCE Although the best-known cause of a mass extinction is the asteroid impact that killed off the non-avian dinosaurs, in fact, volcanic activity seems to have wreaked much more havoc on Earth's biota. Volcanic activity is implicated in at least four mass extinctions, while an asteroid is a suspect in just one. And even in that. Objects were chaotically flying around at the start of the solar system, building the planets and moons. There is evidence that after the planets formed, about 4.1–3.8 billion years ago, a second large spike of asteroid and comet impacted the Earth and Moon in an event called. late heavy bombardment. . The extinction that occurred 65 million years ago wiped out some 50 percent of plants and animals. The event is so striking that it signals a major turning point in Earth's history, marking the end of the geologic period known as the Cretaceous and the beginning of the Tertiary period. Around 65 million years ago, something unusual happened on BdcR.
