In the age of the dinosaurs, what happened in the 11 minutes when the meteorite hit the earth?

The entire earth was shaken, the whole world fell into a dark night full of fire, and tsunamis were raging along the coast.

In the age of the dinosaurs, one day 65 million years ago, a meteorite with a diameter of 15 kilometers roared towards the earth. Its speed was more than 20 times that of a bullet, and it hit hard, especially in Mexico. Peninsula of Catan. According to relevant expert estimates, the energy generated by the impact was stronger than the explosion of a billion atomic bombs. Experts discovered a huge crater with a diameter of more than 180 kilometers. After the meteorite hit the earth, wildfires spread instantly, violent tsunamis erupted, and earthquakes with an intensity of over 11 swept across the entire earth.

The huge fireball at the impact point rose to 160 kilometers. Up to 70 billion tons of rock and soil powder formed a cloud layer filled with fine dust and crystals in the outer atmosphere, and spread rapidly in all directions. This is a type of ejecta cloud. As dust spreads at high altitudes, trillions of tiny particles enter the atmosphere. The high-speed diffusion friction generates a large amount of heat, causing the temperature of the dust cloud to reach as high as 8,000 degrees Celsius. The cloud rapidly heats everything below. , coupled with the raging volcanic eruptions caused by earthquakes in the earth's crust, countless lives were killed instantly.

Without sunlight, many plants died one after another. There was a lack of food, and the surviving large herbivorous animals died one after another. After that, carnivorous animals also began to suffer, and the entire biological chain began to collapse. The mass extinction of various species began, with only small animals and marine life barely able to support themselves. According to expert research, after this disaster, all animals weighing more than 25 pounds on land became extinct.

A large part of the reason for the extinction of dinosaurs is that they were too big and needed too much food. However, plants did not grow without sunlight and died little by little.
