If all the mountains were razed to the ground, what would happen to the earth?

We know that there are many mountain ranges on the earth, and these mountain protrusions are also caused by the impact of a crust and plate in the earth's interior, and these unevenness is called mountains or hills, and even the average altitude of more than 3 kilometers is called the highest mountain range. And we through the satellite ** earth, found that there are a lot of unevenness, if we raze these uneven mountains to the ground, then how will the earth change, there will probably be the following situations. <>

First, the land area of the earth will increase. First of all, if we flatten all these mountains on the earth, then we have a lot more land area. After all, the mountains are confined to human habitation.

And if we turn these mountains into habitable flat land, then the population area of the earth will rise dramatically, such as the Himalayas in western China.

If it were razed to the ground, the gap between the population of eastern and western China would be greatly reduced. The western region will also become another important region for economic development. <>

Second, the area of the oceans in the Earth's interior may shrink. And secondly, if we were to flatten all these mountains on Earth, the size of the oceans would shrink. Because of many inland rivers nowadays, one of their water supply basically comes from these mountains, such as the Lancang River in China.

In the source of the three rivers, one of their river supplies is basically generated from some mountain areas in China. If all of these mountain ranges were wiped out, there would be less water in the planet. <>

Third, regional transportation will become more convenient. The last point is that if we really raze all these mountains to the ground, then one of the exchanges in the western part of China will be much more convenient, and the Silk Road in China.

There will be another change, and it is very likely that we will be in West Asia or Southeast Asia.

A relationship between the region has changed dramatically.

If all the mountains are razed to the ground, then there will be more changes on the earth, and the temperature of the earth may be higher, so it is possible that the glaciers in the north and south poles will melt faster, which is likely to worsen the earth's environment.

Mountains have important ecological resources and make an important contribution to the ecological balance, and if the mountains are razed to the ground, the ecology will be severely damaged, and the earth will become devastated and lifeless.

Who knows? At that time, there were only immigrants.

Research shows that the operation of the entire universe is a complete system, and its operation follows a principle, which I call the "gearbox" principle. Now back to the question "What happens if the direction of the Earth's rotation is reversed", the answer is that if the Earth wants to reverse, first of all, the Sun will reverse; Second, if the Earth is reversed, the Moon must also be reversed.

It will affect atmospheric circulation, ocean circulation, etc., and have an impact on the climate of all continents. If one day the earth is reversed, all existing laws and existing things in nature, including all animals and plants, will be extinguished, and they will return to the furnace again, start anew, and start again.

If it is like a reversal now, it is estimated that the water of the Great Plains can reach the Himalayas, the mountains and rivers will be razed to the ground, there will be no houses left, all living beings will be destroyed, and the entire earth will return to the era of famine. Why? If you've seen a big car driving at high speed and crashing into an oncoming bicycle, you'll be convinced.

The sun is coming from the west. Changes in atmospheric circulation, even natural disasters, changes in climate, and many physical properties change. Technological products cannot be used. It's horrible, it's just people's reverse thinking.

The earth's rocks, seawater, organisms, and atmosphere all belong to the earth. If you change direction all at once. It was a much milder scene.

Ocean currents will be observed within a few days and the atmospheric circulation will change. The moon will be thrown out right away. Satellites will either fly into space or crash to the ground.

All navigation is closed. The changes are endless.

Let's make an analogy, the car brakes suddenly, the people in the car will rush forward, the earth rotates at a speed of about 500 meters per second, tell it to stop and reverse, the consequences are unimaginable, in this way, all objects on the earth are slanting forward at a speed of about 500 meters per second, big trees are uprooted, people and houses will be thrown into space, the sea water of the four oceans will have huge waves, the waves will flood the seven continents, and the peaks above 5,000 meters above sea level will become islands. This is the end of the world.

We humans regard the time for the earth to revolve around the sun, that is, about 365 days as a year, and the time for the earth to circle around itself in space, which is equivalent to 24 hours, is a day. This is our time system living on Earth, and if our Earth revolves and rotates in the opposite direction, we will still be 24 hours a day, 365 days a year, as long as the speed is exactly the same as we were before. But there is one thing that will be different from what we have seen before, because our sunrise direction has been reversed, which is what everyone calls "the sun has risen in the west".

In our solar system, there is a planet, Venus, which is exactly as you can imagine, and if you look at the sunrise from Venus, the sun rises in the west.

If the earth reverses in an instant, the most obvious is the large tsunami, frequent extreme weather, abnormal movement of the earth's plates, human beings and other animals will inexplicably die of various unexpected disasters, and animals will take a long time to adapt to the irreversible natural environment.

The sun rose in the west. When a human launches a spacecraft, it is launched in a westerly direction, and gradually lands from east to west. Earth became another planet that rotated from west to east after Venus.

In addition, the earth's rivers, ocean currents, atmosphere, magnetic field, etc., will be adjusted according to the change in the direction of the earth's rotation.

What happens to the Earth's rotation in the opposite direction, and what's different about that Earth?

Based on the 10-kilometer radius of a single megaton nuclear warhead, the destruction area of each nuclear warhead is 300 square kilometers. The Earth's land area is about 100 million square kilometers. Therefore, it would take 500,000 million-ton nuclear warheads to blow up all the land.

Nuclear ** can destroy human civilization because it destroys the environmental balance of the earth, not really bombing the earth again, nor blowing the earth to pieces.

To destroy the world, about one or two thousand nuclear warheads are enough, and a large-scale nuclear ** will throw a large amount of smoke and dust into the upper atmosphere, block the sunlight, make the ground temperature drop, become very cold, plant photosynthesis declines, and species are extinct in large numbers. This phenomenon is known as a "nuclear winter".

To put it simply, as long as the Soviet Union dropped 2,000 nuclear warheads on its own soil at one time, even the United States would be doomed.

There is no definite answer to this question, and I think that 2,000 pieces of the earth's land will be enough to raze the earth's land to the ground, leaving not a single grass to grow.

At present, the number of nuclear warheads stored in the US nuclear arsenal has reached more than 10,000, of which at least 5,000 are on combat readiness, and these nuclear weapons alone are enough to destroy the earth several times.

Approximately 1,000 pieces, based on land area.

Yes, because there is no friction between the turns used to build the house, and there is no stickiness between the cement, of course it will fall.

All objects move around and start moving at a constant speed without stopping, and the same goes for houses, of course

Yes ! will not exist! Because without friction, the object cannot resist the gravitational force and stand up!

No. Houses are not built like building blocks! If all the building materials are built like building blocks, of course they will slip when the wind blows.

The problem is that there is still a force between molecules, such as a piece of iron, even if there is no friction, it will not disperse into iron powderTherefore, I do not think there is any scientific truth to the assumption of razing the ground.

Static friction also belongs to the first category of friction, and the absence of motion between objects does not mean that there is no friction, so the respondent carefully considers this issue.

Because the foundation of the building is underground, the building will not collapse even if there is no friction.

First of all, you need to know what friction is, and then you will find that buildings also rely on friction to stand on the ground. There is such a possibility, it will be flattened.

If the friction is gone, cars on the road will crash into the building, eventually leveling the building.

If there is no friction, there is no resistance, then we don't need cars or trains. Hehehe. Awesome. But it's still attractive, so we can't be a plane, it's a pity, alas.

Everything has to be stationary, or to keep moving in a straight line at a constant speed, knowing that there is a force to stop it or change the direction of its motion. The first law of the old cow can explain this phenomenon.

It can't be said that razing to the ground, a gust of wind blows, and all the buildings move in the direction of the wind (the wind is horizontal, gravity is straight down, it will not be balanced), so the earth is full of buildings wandering.

Nothing remains the same. It won't work with each other!

Like a bullet, the body of the projectile is not hard enough like a rubber bullet, it will not be broken, at most it is a crater 1 kilometer deep, the same weight of water and iron impact is too bad, the water impact is low and the hardness is not enough, there is no asteroid with a diameter of a few hundred meters that can smash the earth through, the hardness is not enough, it is blown up, the fragments are like 10 times the speed of a sonic cannonball, and the speed continues to decrease, the sound shock wave is very large.

How to hit, eat and hold on, the earth is in **, the edge of the earth is in **, this kind of news is meaningless, bluffing children.

I read an article, and the author of the article is also an authority: he probably said that it depends on the angle of the asteroid hitting the earth, if it hits the earth straight, then most people in the world are finished, if it hits it diagonally, then the power will be reduced a lot, and it is too late to find it, and the existing means have no time to prepare.

I haven't heard of this asteroid, but with the current technology of human beings, even if it really comes, it comes directly in the direction of the earth, and human beings can deal with it, even if they can't destroy this asteroid, they can change its orbit to a great extent, in short, they don't panic.

It will definitely survive, and if humans really find that an asteroid will hit the earth, they will definitely find a way to solve it.

If it does, there is no chance that humanity will survive.

There are too many people who spread rumors and make trouble, is it useful to be afraid that the world will not spread the news of the people?

I believe that with the development of science now, we will definitely find a good way to solve it, and we must survive well to create a better tomorrow!

I think if I really hit it, no one will survive.

It is impossible for an asteroid to hit Earth.

Of course not, don't you think?

We played ourselves to death!

I don't think I'll survive.

Although the probability of an asteroid colliding with Earth is small, the damage caused by the collision is often devastating.

If an asteroid with a diameter of less than 10 meters hits the Earth, its energy is equivalent to 50,000 tons of TNT explosives, and it will become a "meteorite fireball" in the atmosphere, which will incinerate itself into fragments. All this happens high in the atmosphere and does not cause much harm. This impact occurs about once every 10 years.

If an asteroid with a diameter of 10-100 meters hits the Earth, its energy is equivalent to tens of millions of tons of TNT explosives, which could destroy a city and kill tens of millions of people. Once it falls in a frequent area, it will trigger above level. This impact occurs approximately once every 300-1000 years.

If an asteroid with a diameter of more than 100 meters hits the Earth, its energy is equivalent to tens of millions of tons of TNT explosives, and if it falls in the middle of the ocean, it can set off a tsunami up to 200 meters on both sides of the ocean. This impact occurs approximately once every 10,000 years.

If an asteroid with a diameter of more than a kilometer hits the Earth, if it falls in the ocean, it will be enough to set off waves 3,000 meters high, and even if it is 300 kilometers away, the waves will still be more than 500 meters high. If it hits land, there will be a "star-strike winter", when the earth is shrouded in a thick cloud of dust and the sky is dark for several years. A quarter of the world's population will lose its life, and human civilization will regress.

Such an impact is estimated to occur once in more than 500,000 years.

Not long ago, the head of the NEO Monitoring Program announced that an asteroid with a diameter of 400 meters could collide with the Earth in 2029 with a probability of 1,300. "The possibility that 2004 MN4 will collide with the Earth on Friday, April 13, 2029, is not ruled out now," the person in charge said.

If such an unfortunate thing were to happen, the consequences would be very serious. If it crashes into the ocean, there will be a tsunami; If it falls on land, it will induce violent **and**. ”

But we can rest assured that technology is advancing so fast that scientists will do everything they can to prevent the possibility of a collision. The experts of the National Aeronautics and Space Administration (NASA) in charge of the Near-Earth Object Monitoring Program have officially announced that the possibility of a collision with the Earth by the asteroid number 2004 Mn4 in 2029 has been completely ruled out.

In addition to this, NASA scientists have also confirmed that the 2004 MN4 asteroid will not pose any threat to us throughout the 21st century.
