What is the name of the asteroid that hit the Earth 65 million years ago? What are the specific para

It is an unnamed wandering star with a diameter of 10,000 kilometers.

65 million years ago, Maya was hit by this wandering star into several small stars, namely: Ceres, Homo sapiens, Marriage, Vesta, Righteousness, Vulcan, and Sapo. 65 million years ago, the Mayans were very technologically advanced and very traditional, and lived a rich and happy life, but this year, when the high priest held a worship ceremony in the square, the stargazer came to tell the bad news:

A wandering star with a diameter of 10,000 kilometers is heading towards our solar system. It first crashed into Neptune, causing Neptune's shift, and then crashed into Saturn, smashing Saturn's moons into pieces, forming today's beautiful rings of Saturn. It crashed into Titan again, causing Titan to form a reverse trajectory satellite.

Immediately after the wandering star changed its orbit and crashed into Jupiter, making Ganymede.

8. Ganymede. 9. Ganymede.

Ten. 1. Callisto also becomes retrograde. Then, the wandering star flew towards the Mayan star. The Mayan emperor declared resistance.

All kinds of ultra-modern **together**, trying to change the trajectory of the wandering star, but still watching the wandering star get bigger and bigger in the sky. There was no way, the Mayan emperor tearfully announced the relocation of the whole country.

All factories are working day and night to make flying saucers. Fight for one, the largest flying saucer is 20 stories tall and is used by royal staff and the Royal Guard. The people helped the old and the young, bid farewell to their homeland and boarded the flying saucer. Fly to the distant star Pedar in the constellation Draco.

After that, the wandering star collided with the Mayan star, and the two stars collapsed, and the Mayan star split into several small stars and flew along a new trajectory. The splinters of the wandering star smashed into the earth, raising a huge dust mist that covered the earth the next day.

Most of the dinosaurs on Earth were completely extinct, and only a few of them hid in the valleys. Become the Lake Kanas Monster and the Loch Ness plesiosaur.

It's a drop, and the dust kicked up envelops the whole earth, causing the earth's temperature to plummet, plants can't photosynthesize, and dinosaurs may become extinct, with a diameter of 10 kilometers, an electric car for 20 minutes, and a speed of Mach 40.

64 kilometers, hit other planets halfway, there are only kilometers, speed 72,000 kilometers per hour, tsunami, more than 90 meters, **, volcano, typhoon, **yes fire on the sky, change clouds, spew dust clouds.

Is 10,000 kilometers still called an asteroid?

65 million years hit the earth is the "King Kong No. 1", the speed of 15 kilometers s, causing a diameter of 200 kilometers of crater, the dinosaurs also perished, at that time 60% of the earth's life extinct, only some of the creatures in the sea survived, is a catastrophe in the history of the earth.

King Kong-1 is 10 kilometers in diameter, mainly composed of quartz, and has an impact speed of 10 to 15 kilometers per second. Causes a magnitude.

The center of the impact crater is located in Gaoping District, Nanchong City, Sichuan Province, and the part of the Huanxing Mountain, which encloses thousands of square kilometers, stretches from the center of Peng'an County and Yingshan County to Yuechi County, and is still clearly visible today. The larger Sichuan Basin was the result of an earlier impact.

Caused by an asteroid hitting the Earth 65 million years agoDinosaurs became extinct

The asteroid impact 65 million years ago wiped out 75% of the Earth's species, fundamentally destroying the entire Earth's ecosystem and food chain, and causing a global supervolcano.

The explosion and the entire earth entered a "nuclear winter, and the giant dinosaurs at the top of the food chain ran out of food." The planet is not ecologically strong enough to feed these dinosaurs. Two million years after the impact, non-avian dinosaurs also became extinct.

Dinosaur Origin:

In fact, humans have a long history of discovering dinosaur fossils. Long before the discovery of avian dragons, Europeans knew that there were many huge fossilized bones buried in the ground.

It wasn't until the discovery of the avian dragon and the comparison with the iguana that the scientific community preliminarily determined that it was a group of lizard-like species.

of reptiles that have long been extinct.

In 1842, the British paleontologist Sir Richard Owen (1804-1892) used Latin.

They were given a name, and the Latin word is made up of two roots, the first root meaning "terrifying" and the second root meaning "lizard". Since then, "terrifying lizards" have become a general term for a class of reptiles. Of course, this is limited to Latin's ability to make words.

The term "dinosaur" was coined by Japanese biologists and introduced to China. Translate this Latin name as "dinosaur". Dinosaurs are not lizards. It is one of the first advanced organisms on Earth to be able to walk upright on its own.

1.Into the atmosphere.

After a second, the meteorite hits the Earth's surface. The rest of the meteorite also suddenly turns to steam, and it happens**. Since the site of the impact at that time was still a shallow sea, the huge crater was later swallowed up by the sea, leaving only traces of elemental changes and losing its physical shape for endless years.

The dinosaurs became extinct.

During this time, there was a huge asteroid in space, which hit the Earth.

2.Currently, the extinction of the dinosaurs was caused by an asteroid impact. 65 million years ago, an asteroid with a diameter of more than 10 kilometers hit the Earth on the Yucatan Peninsula in Mexico.

Although it is only 10 kilometers in diameter, it creates craters in diameter of hundreds of kilometers, but over time it obscures historical sites. Because the force of the impact is so strong, it is disintegrated into pieces after the impact. These fragments are scattered everywhere and then constantly buried in the dust of history.

3.When an asteroid hits the Earth, it will hit a large crater on the Earth because of its non-hand-burning speed and the very large kinetic energy it carries, which can eliminate part of the asteroid. The violent impact will also cause the asteroid to disintegrate, and a large amount of asteroid material will splash around, which is one of the reasons for the mass extinction of life on Earth in winter; At the same time, the heat energy converted by the impact melts or even vaporizes the asteroid, so the asteroid does not throw stones on the beach like we do.

4.Asteroids are usually very velocity, and after entering the dense atmosphere of the Earth, they will have severe friction with the air in the atmosphere, and the resulting high temperature will consume too much material in the asteroid, and in general, most of the asteroid's head will be depleted in the process. According to computer simulations, the impact angle of the asteroid with the Earth's surface is 40 to 60 degrees, and the instantaneous velocity at the time of impact.

Not less than 25 kilometers per second.

The meteorite fell on the Earth's mantle, when the extinction of the dinosaurs tens of thousands of years ago was caused by the impact on the Earth.

I think I should be swallowed by a black hole. Because after hitting the earth, he was sucked into it by the huge magnetic field emitted by the black hole.

These meteorites have completely dissipated, and after the influence of the ring, these stones have completely dissipated, and they have all been scattered with the wind.

He was crushed to pieces on the spot, and he left a particularly large scar on Earth, a crater that can reach 180 kilometers in diameter.

The tsunami caused the Yucatan Peninsula to move from South America, North America and Africa, pushing rocks together to form rock piles.

The asteroid dealt a devastating blow to the dinosaurs that ruled the Earth at the time, and crashed into the 180-kilometer-wide Chicxulub crater in Mexico.

It caused a particularly severe change, and then it also led to the direct extinction of the dinosaurs, but also had a particularly serious impact on the climate, and it also led to a volcanic eruption, and then it also led to the direct extinction of an era.

After the attack on the earth, a large crater was created on the surface of the earth, and many creatures on the surface were wiped out.

About 65 million years ago, an asteroid hit the earth and caused the extinction of the dinosaurs, and an asteroid with a diameter of 10 kilometers hit the earth, producing an impact force equivalent to the power of 10 billion atomic bombs. Although this shockwave is large, the range of its instantaneous destruction is not very large.

The real horror of an asteroid hitting the Earth is actually the impact on the Earth's interior**. The Earth is a rocky planet, and its interior is not as calm as the surface, but an environment full of high temperature and pressure, in which a large number of liquid substances such as hot rock awards exist. The violent crustal movement caused by the impact of an asteroid on the earth will cause many volcanic eruptions around the world, which is the most terrifying situation.

"65 million years ago, an asteroid hit the Earth and caused the extinction of the dinosaurs, and the impact site was on the Yucatan Peninsula in Mexico, and the impact was equivalent to the power of 100 trillion tons of TNT explosives, and the dust splashed up covered the world. ”

The extinction of the dinosaurs is directly related to the impact of the asteroid, an asteroid large enough will release a huge amount of energy when it hits the earth, and at the same time, the asteroid will completely disintegrate, splash into the sky in the process of violent impact, and then fall around the world, the impact of the impact is directly related to the shape of the asteroid, if the asteroid is large enough, the raised dust and its own debris will splash far away.

An asteroid hit the Earth 65 million years ago, causing the extinction of the dinosaurs.

In 1980, Nobel laureate in physics Louis Alvarets, his sons Walter Alvarets, Frank Asaro, Helen Michel and others found that the global Cretaceous and Paleogene strata were found to contain higher levels of iridium than normal. For example, the iridium content of the two formations in the original study was 30 times and 130 times the normal standard, respectively.

Iridium is a very rare metal in the earth's crust and belongs to the siderophilic element; Most of the ferrophilic elements settle into the Earth's core, such as iron, during the planetary differentiation. Since iridium is often found in most asteroids and comets, Alvarez et al. believe that an asteroid hit the Earth's surface at the beginning of the Cretaceous and Paleogene periods.

Other Sayings About Dinosaur Extinction:

There is clear evidence that the largest retreat since the Mesozoic occurred at the Cretaceous Maastricht Order. In some Maastricht terraces around the world, the earliest part is the seabed, the earlier part is the coastal layer, and the latest part is the continental formation.

There is no sign of tilting or bending of these formations as a result of the orogeny, so the most likely explanation is sea retreat. There is no evidence of a cause of the retreat, but the most common explanation is that the activity of the mid-ocean ridges decreases, and these large seamounts slowly settle in the seafloor strata with their own weight.

Large-scale sea retreat has led to a significant disappearance of the continental shelf, and the marine life that inhabits the continental shelf is the most abundant, so sea retreat may lead to the extinction of marine life.

Studies have also shown that changes in sea level are not enough to cause such a severe ammonite extinction. The decline in sea level may cause changes in the atmospheric circulation system and the ocean current system, resulting in climate change. Shrinking ocean areas will also reduce the albedo at the surface, which in turn will increase global temperatures.

Large-scale retreat has also led to the disappearance of many continental seas, such as the western inland seaways of North America, which have been absent for about 10 million years. At the same time, due to the relative rise of the land, the length of the rivers is longer, which expands the living area of freshwater. Changes in the growth and flow of oceans and freshwater areas have led to an increase in freshwater vertebrates and a decrease in the abundance of marine organisms such as sharks.
