DISASTER

Hello. Right now I want to talk with you about the most destructive and murderous disaster in the history of Earth. When we talk about natural disasters, we usually take them as seriously as we shouldn't. A Disaster has been being a common situation on Earth since its inception. We get bad news every year, but the worst thing is that more and more disasters are becoming not natural. We create problems for us by ourselves. But when your planet is being attacked by a large asteroid or comet about 11 to 81 kilometers (6.8 to 50.3 miles) in diameter like, for example, Chicxulub impactor,  people are not guilty, there is nothing to do. Every T-REX would agree with my words.

 Sixty-six million years ago, dinosaurs roamed the Earth. Initially, A giant object came flying through space and hit our planet. The tremendous object landed in the water near Mexico. It must have been a comet or asteroid. It was traveling 150 times faster than a jet. The asteroid hit the Earth with magnificent force. Its blow is known as an impact. By the way, what Is The "Crater of Doom"? The giant space rock left a large crater. The hole in the ground was deep. The abyss is estimated to be 150 kilometers (93 miles) in diameter and 20 kilometers (12 miles) in depth. The cavity is known as Chicxulub (was named after a nearby Mexican town).  The crater is being buried under the ocean floor right now. Also, I can't forget that the impact caused all sorts of horrifying situations.  It made the land shake and crack apart. The hit produced a megatsunami over 100 meters (330 ft) tall. At first. it turned the Earth warm as a greenhouse. The emission of dust and particles had been covering the entire surface of the Earth for numerous years, probably a decade, creating a harsh environment for living things. Production of carbon dioxide, which is caused by the destruction of carbonate rocks, led to a sudden greenhouse effect. Forest fires filled the skies with smoke. Over a decade or longer, Sun's rays had been being blocked from reaching the surface of the Earth by the dust particles in the atmosphere, cooling the surface dramatically.  Consequently, Temperatures cooled, the planet became as cold as an icebox.  That is why photosynthesis by plants was also interrupted, affecting the entire food chain. Three-quarters of the kinds of animals living on Earth were wiped out. Most of the dinosaurs were killed off. Honestly, Some survived: crocodiles, turtles, and small, rodent-like mammals. These small mammals are our ancestors. So, let's talk about the crater itself. A peak ring is a chain of mountains. It forms around a crash. The peak ring forms in two stages. First, bedrock pushes up following the impact. Then, it falls back down in a ring shape.  Finally, This is called the K-T event. It marked the end of the Cretaceous period and the beginning of the Tertiary period. 

As a result, this event changed the world. Maybe, it gave us a chance to live, but, at the same time, it took millions and billions of other lives. As for me,  It is the central tragedy in the story of  Earth.
