Others say with ingenuity that it is because the giant animals such as dinosaurs eat too much and constantly fart, releasing a large amount of methane gas into the air. Because of their large number and long survival time, the destruction of the Earth's ozone layer creates a devastating climate.
There are even people who say that aliens ran to the earth to hunt for results because they felt that dinosaur meat was particularly delicious. The evidence is that the dinosaur bone fossils they found in the Arctic have traces like laser cuts. In short, it can be said that it is a variety of things, no wonder. However, it is generally accepted that the meteorite impact said.
In 1980, American scientists discovered high concentrations of strontium in the formations of 65 million years ago, which were tens or even hundreds of times higher than normal. This concentration of cockroaches can be found in the meteorites, so scientists linked it to the extinction of dinosaurs. According to the content of strontium, it is also estimated that the impacting object is an asteroid equivalent to 10 kilometers in diameter.
Such a large meteorite hitting the earth is definitely an unbeatable blow. It is calculated by the intensity of the earthquake, which is about 10 on the Richter scale. The diameter of the crater produced by the impact will exceed 100 kilometers. Scientists have spent 10 years and finally got a preliminary result.
They found this pit in the strata of the Yucatan Peninsula in Central America. According to projections, the diameter of this pit is between 180 and 300 kilometers. Now, scientists are still doing further research on this big pit.
Scientists began to paint a dramatic scene for us 65 million years ago. One day, the dinosaurs also ate and drank in the earthly paradise. There was a blink of white light in the sky. A huge stone with a diameter of 10 kilometers was equivalent to a medium-sized city descending from the sky. It was an asteroid that crashed into the sea at a speed of 40 kilometers per second.
It hit a huge deep pit at the bottom of the sea. The seawater was quickly vaporized. The steam sprayed tens of thousands of meters into the sky, and the tsunami that picked up was up. 5 kilometers, and spread at a very fast speed, the sky swept across everything on the land, and the raging waves swept the surface of the earth and merged with the back end of the impact point, where the enormous sea force triggered the strong volcano on the Deccan Plateau. The eruption also changes the direction of the movement of the earth's plate.
What a terrible disaster it was. The meteorite hit the earth and produced overwhelming dust. The polar snow melted, the plants were destroyed, and the volcanic ash was filled with the sky. For a time, there was no day, the temperature plummeted, the rain fell, the flash floods and the mudslides took away the dinosaurs and buried them.
In the next few months and even years, the sky is still tumbling, and the clouds are densely covered. The earth enters the low temperature because it does not see the sun all year-round, and the earth is silent for a while. This is the end of an era in biological history.
Whether the above things have happened, the extinction of dinosaurs will be a peculiar thing. Fortunately, we have now obtained some precious dinosaur fossils, enabling scientists to carry out research work. We hope that this mystery will be solved in the near future.
At the same time, we should know that any kind of creature must undergo the process of production, prosperity, and extinction. This is the law of nature and will not change because of the huge prosperity of that species. The dinosaurs became extinct, and a new era emerged. More and more advanced biological worlds decorated the earth better.
