Is it really the reason why the dinosaurs went extinct and disappeared, was it really an asteroid th

It is the extinction caused by the asteroid hitting the earth, but this process lasts for up to 1 million years, when the asteroid hits the earth, the dinosaurs are not completely extinct in an instant, but the climate upheaval caused by the impact, the dense dust covers the sun, causing plants to be unable to photosynthesize, and the herbivorous dinosaurs are extinct after the plants die, and the carnivorous dinosaurs are extinct because they have no food.

65 million years ago, an asteroid the size of Witt Island crashed into Earth, causing the dinosaurs to go extinct. The crater shows earthquake quartz and other evidence of impact. The energy released by the asteroid impact on the Earth caused a continuous stream of large**, causing forest fires and causing the extinction of half of the species.

Not sure, because they think that the dinosaurs were made up, and humans can only observe 93 billion light years, in this area, we find that there are tens of thousands of stars in the universe, but unfortunately among the many stars, only the earth gave birth to life, according to probability, this is really illogical.

The asteroid impact caused the extinction of the dinosaurs has basically become the general consensus of scientists of all kinds, and people often agree with this statement, not only because it is a hypothesis or basic theory, but also because it has physical evidence of microbial and geoenvironmental archaeology, such as meteorites and craters, the most fundamental causes of the extinction of dinosaurs, most of which have been discovered by experts.

Geographers believe that the meteorite that caused the extinction of the dinosaurs fell to the coast of the Yucatan Peninsula in Central America, Spain, where a huge collision created a crater with an aperture of more than 150 square kilometers, and scientists believe that the meteorite had an aperture of nearly 10 kilometers before falling to the earth. The energy released by this huge collision is equivalent to the power of 120 trillion tons of yellow explosives, which is actually the power of 6 billion Hiroshima atomic bombs.

So what about the 10-kilometer planet after the collision? Why can't you see it on the ground? In fact, although it collided with a huge crater on the ground, a considerable part of the planet evaporated during rapid friction in the atmosphere, but because the planet is indeed very large, a considerable part of it also fell on the earth, and the main manifestation of its meteorite behavior is now likely to be under a village called Chicxulub in the Yucatan Peninsula of Spain, Central America, but because he had already cracked into a lot of debris before he fell to the floor, Therefore, there will be some meteorite debris in and around the crater, but since more than 65 million years have passed, it is really difficult to find them.

That is also the impact usually caused the extinction of the dinosaurs, not because of the impact caused by the tsunami super volcano, etc., often the impact seriously affects global warming, because after the impact there is a large amount of smoke and dust emitted over the world, and the volcanic magma of the volcanic eruption together blocks the sun's rays on the earth's surface, the time is very likely to be close to hundreds of years, which leads to a rapid decrease in the average temperature on the earth, many plant species on the ground die, large, medium and small triceratops not only lose food**, It was also difficult to withstand the long-term cold, so they were all wiped out, and only arthropods and a few amphibians, mammals, viviparous animals, and some large, medium and small theropod dinosaurs survived, and these large, medium and small theropod dinosaurs could sail because they evolved their feathers, and slowly evolved into modern birds.

Because the asteroid crashed into the interior of the Earth, and the Earth was turned upside down, the asteroid disappeared.

I think it's probably because the asteroid disappeared after a strong impact.

The above is the general process of impact. We can clearly understand that the asteroids that led to the extinction of the dinosaurs were partly consumed by the atmosphere, and partly melted or vaporized by the high temperatures generated during the impact. (Some were thrown away, some merged with the earth's matter), and the remaining hard matter fell into the depths of the earth.

No, it won't; Because the asteroid hits the earth, the number of organisms killed directly is limited, and it will not cause extinction in a large area, which will cause plants to be unable to photosynthesize, causing a large area of plant death.

I think human beings may become extinct, because the dinosaurs at that time were already quite powerful species, and they have all been wiped out under the circumstances of that time, although human beings are now very advanced in science and technology, but in the process of development, they still can't catch up with the fatal devastating blow, so they may be extinct.

Yes, the harm caused by the asteroid hitting the earth is very devastating, and it will lead to the extinction of human beings, because a large amount of water will evaporate, and all animals and plants will be burned, and the root of life will be lost.

The risk of an asteroid colliding with the Earth is so devastating that it will lead to the extinction of humanity, because the evaporation of water, the plants and animals are burned, and they lose their lives.

We don't know about the future development of the entire universe now, but we have put forward a vision for the future, and we believe that human beings will be able to land on other planets in the future, and they will be able to move planets, which is a planning dream that we currently have for the future development of human beings. But we can't rule out that in the future, our earth will also be hit by 66 million asteroids, so about the asteroid that once hit the earth and caused the extinction of the dinosaurs, finally went to **? <>

1. Perhaps the first conjecture is that it has become a continent or an island as we know it today. First of all, the first point is about the asteroid that hit our earth and caused the extinction of the dinosaurs, and may become a continent or island as we know it now. After all, the impact of this asteroid at that time was 10 times greater, which led to a huge change in the environment and climate of the Earth's interior.

Especially in terms of temperature, it directly led to a Cretaceous period at that time directly reached a later ice age, so after the temperature decreased, this is undoubtedly a huge blow to those animals and plants living on the earth, these dinosaurs were extinct at that time, and the reason for being so clean is here. <>

Second, it may have become some dust in a certain area now. And when this asteroid collides, when the huge forces interact with each other, it is also possible to cancel each other out, and directly impact the earth at that time, this asteroid can be directly destroyed due to the action of mutual forces, and become some dust and gravel as we know it now. <>

3. It may become a part of the earth. The last one is about the asteroid that hit at that time, which directly became part of our current Earth. After becoming a part of the earth, we humans cannot detect the existence of this asteroid.

It completely evaporated after the impact and released the energy equivalent of 120 trillion tons of yellow explosives, which is also responsible for the drastic changes in the Earth's environment.

The asteroid that hit the earth and caused the extinction of the dinosaurs may eventually disappear into the vast universe, and the asteroid that hit the earth and caused the extinction of the dinosaurs also suffered a very large loss after hitting the earth, so it has also disappeared.

The asteroid that hit the earth and caused the extinction of the dinosaurs is still in our earth in the end, but we haven't studied anything so far, and I believe that according to the development of science and technology, we will definitely study its whereabouts.

It is said that the asteroid impact made the dinosaurs extinct, so no matter what, there will be residual asteroid fragments, why is there only a pit? Was the meteorite completely melted?

Obviously, the asteroid 65 million years ago disappeared without a trace. It left a huge scar on the Earth, a crater with a diameter of up to 180 kilometers! It is Chicxulub Crater on the Yucatan Peninsula in Mexico.

Chicxulub crater cannot be seen directly. The asteroid impact 65 million years ago attracted attention because many scientists believe that the impact was closely related to the extinction of the dinosaurs. The inner wall of the crater has a diameter of 180 km, a maximum diameter of 300 km and a depth of 20 km.

The energy generated by the impact, equivalent to more than 900 trillion tons of TNT explosives, triggered a tsunami more than 1,500 meters high, which almost wiped out the entire Americas. The huge shock wave led to a worldwide ** and volcanic eruption, and a large amount of hot ash was blown around the world by hot winds, igniting many surface wildfires. At the same time, the carbon dioxide, water vapor and dust produced by ** rise into the air, isolating the sun from irradiating the earth.

After the impact, it triggered a global ** and tsunami, the world did not see the light of day for a few months, and in the following hundreds of years, supervolcanoes and ** continued, and almost all large-sized animals were wiped out; Then the restoration of the entire Earth's ecosphere took millions of years.

The asteroid broke apart at the moment of impact and scattered in all directions, and some of the debris flew hundreds of kilometers too fast, and many of the debris was covered up with the change of time. There are many more molten states that smash into the ground, and when cooled, the ground of impact craters is formed.

Others with faster debris will even fly back out of Earth, potentially crashing into other celestial bodies when they go into space. For example, meteorites on Mars have also been found on Earth.

Therefore, after the impact, part of the asteroid is reduced to fragments and bounced to other places, and the core part is directly integrated with the ground and becomes a part of the earth.

In fact, the formation process of the earth was a process of continuous impact of asteroids at the beginning. In the process of the formation of the earth in 4.6 billion years, it is the cumulative process of impact, and the thickness and diameter of the continuous impact are 12,000 kilometers, and the current surface of the earth from the center of the earth to the current surface is the result of the continuous impact of meteorites in the universe.
