By smashing into the Earth, the asteroid impact released huge amounts of dust into the atmosphere. This dust blocked the sun’s rays from reaching the surface of the Earth and this is bad news 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 Last year, a research team drilled down more than a kilometre to reach the rocks that bear witness to the impact. The Earth’s crust flowed like liquid in the wake of the event, lifting and then What’s more, he thinks that clues about the catastrophe are hiding in plain sight, embedded in the creation stories of cultural groups around the world. His hypothesis depends on a major reinterpretation of many different mythologies and raises questions about how frequently major asteroid impacts occur. What scientists know about such The catastrophic destruction triggered by the asteroid hitting the Earth resulted in the death of all non-avian dinosaurs in an event termed the Cretaceous-Paleogene (K-Pg) mass extinction. An asteroid the size of a football field – dubbed the “City-killer” – passed less than 45,000 miles from Earth in 2019. An asteroid the size of a 747 jet came close in 2021 as did a 0.6 J6em. An asteroid impact, in contrast with the climate crisis, is an example of a low-probability hazard with an unusually wide range of potential consequences. Asteroids are detritus from the formation “Terrestrial asteroid impact, as exemplified by Australia’s rich geological record of impacts spanning 3.5 billion years, is an important geological process that has influenced Earth’s crustal and biological evolution. As many as 800 asteroids are hovering around Earth, posing many a risk. Some are particularly dangerous like the Apophis asteroid — God of Chaos — that is supposed whiz past earth in 2029 As of 2022, the Earth Impact Database (EID) contains 190 confirmed craters. The table below is arranged by the continent's percentage of the Earth's land area, and where Asian and Russian craters are grouped together per EID 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
