How many billion years is the lifespan of the Earth? The life span of the earth is about how many bi

Scientists analyze that the earth has existed for 4.6 billion years and will continue to last for 5 billion years, so the life span of the earth is about 9.6 billion years.

The Sun is currently in its prime of life, the main-sequence star.

stage, this period of stability will continue for another 5 billion years. After 5 billion years, the sun's hydrogen fuel will gradually burn out, the core will shrink, it will become denser and hotter, and the outer layer will expand dramatically, and it will enter the "old age" of life - the red giant.

Era. At that time, the Sun became larger and annexed Mercury one after another.

and the orbit of Venus, the earth will not escape the catastrophe, will be swallowed up, fall apart.

In addition to the influence of the sun as an external factor, the lifespan of the earth will also be affected by human factors and other factors. For example, human beings will deforest, pollute water resources, emit polluting gases, and even conduct nuclear tests, all of which will have a heavy impact on the planet. Another example is the occurrence of comets.

An asteroid hitting the Earth could also cause the destruction of the Earth. If this were the case, the life span of the Earth would not be 5 billion years.

According to scientists' estimates, the life span of the earth is about 8 billion years, and the life span of the sun is 10 billion years. However, people do not care for the natural environment, and many chemical wastes are seriously polluted, and the life span of the earth may be greatly shortened.

How many more years can the earth live, scientists** The life span of the sun is 10 billion years, and the age of the earth is now 4.6 billion years, if you do not consider the impact of human or other factors on the earth, the result of the earth's life at the end of its life will be swallowed by the expanding sun.

The human factor refers to the wanton deforestation, pollution of water resources, emissions of polluting gases, and even nuclear testing.

Other factors refer to comets and asteroids hitting the Earth, which can also cause the destruction of the Earth. Of course, by that time, human science and technology will be unimaginably advanced, and perhaps we will have already left the earth and moved to other planets.

The Earth is about 100 million years old. The age of the earth is the time when the earth accumulated from the original solar nebula to form a planet to the present day, and the best estimate of the age of the earth by scientists is 100 million years, and the age of the earth is usually referred to as its astronomical age, which refers to the time when the earth began to form.

We only have an imaginary stage of the formation process of the earth, and the life span of the earth is roughly calculated to be 4.6 billion years according to our imagination.

The current life span of the earth is about 4.6 billion years, and the sun can live for another 10 billion years, so the life span of the earth is about 14.6 billion years.

The earth has existed for 4.6 billion years, and the life span of the earth is currently estimated by human beings. Under normal circumstances, planets and moons have no lifespan and can continue to operate without interference from external conditions, while stars have a lifespan, so the lifespan of the sun directly determines the survival of the earth and the moon. The age of the sun is about 5 billion years, and it can continue to burn for about 5 billion years.

The life span of the earth can reach the end of the universe, but if we take into account the inevitable external factors, then the earth can still exist for more than 4 billion years, because after more than 4 billion years, the nuclear energy in the sun will be exhausted, and the sun will expand and swallow the earth.

The life span of the earth should be about 5 billion years, so the earth also has a lifespan, and it should be cherished and cared for.

The Earth's lifespan is 4.6 billion years. The accurate method of calculating the age of the Earth was proposed by Claire Patterson, a scholar at the California Institute of Technology who estimated the age of the Earth at 4.6 billion years using the simple dating method of meteorite lead isotope solution, which has been recognized by modern scientists. Here's how it works:

The Earth is formed by the accretion of stardust in the solar system, formed at the same time as meteorites, and has the same isotopic composition.

Earth's age is the time it takes for the Earth to accumulate from the primordial solar nebula to form a planet. Scientists' best estimate of the Earth's age is 100 million years, and the Earth's age is usually its astronomical age.

There are several different concepts regarding the age of the earth. The astronomical age of the Earth refers to the time when the Earth began to form, which is closely related to the hypothesis of the origin of the Earth. The geological age of the Earth refers to the time from the beginning of geological processes on the Earth.

It is estimated that hundreds of millions of years have passed since the formation of the primitive Earth and has evolved into a layered Earth, so the geological age of the Earth is less than its astronomical age.

The age of the oldest known rocks on the earth is 100 million years, and the geological age of the earth must be greater than this value, and the geological age is the subject of geological research.

45-5 billion years.

Before we go until the Earth is a planet in the solar Sidsonja system, according to the current scientific capacity of astronomy, the sun was born 50-6 billion years ago. The Earth began to form about 5-1 billion years after the birth of the sun. In other words, the lifespan of the earth to this day should be about 45-5 billion years.

It took such a long time to form today's Earth, or rather, such a long time to form today's solar system.

According to scientific research, about 3 billion years ago, the sun began to expand due to the depletion of its own energy. And reach the Earth in about 1 billion years or so, and at the same time, in the process of expansion, the instability of the sun will completely destroy the Earth's environment. In other words, the stable life environment that the earth can theoretically have is only about 30-3.5 billion years old.

This is the entire lifespan of the earth, which is of course very long for human beings.

The shape of the earth:

On the earth's surface, there are mountains, basins, rivers, lakes, and oceans, among others. It can be said that the surface of the earth is an extremely irregular curved surface, but these ups and downs are small relative to the whole earth. The area of the earth is 100 million km2, the area of the ocean is about 100 million km2 of the earth's surface, and the land area is only about 100 million km2.

The maximum undulation of the surface landform is 840 m in average elevation, most of which account for 75% of the total area and are below 1000 m.

The world's oceans determine the main features of the Earth's appearance, because 3 4 of the Earth's crust is surrounded by a layer of water about 4000m thick. The Earth's landforms at the ocean floor of the world's oceans are characterized by ocean basins, mid-ridge mountain systems, faults, and deep troughs. In addition, the Earth is asymmetrical with the equator in terms of shape, for example, the Earth's land 2 3 is in the Northern Hemisphere, only 1 3 is in the Southern Hemisphere, and most of the islands, ocean ridges and deep ocean trenches are in the Northern Hemisphere.

Question 1: How long is the real life of the earth? The life span of the earth should still be very long, and the resources on the earth that you are talking about are getting less and less, which is only related to how long the future of mankind can last.

Theoretical physicist Stephen Hawking**, human beings will be extinct within two hundred years, before talking about a thousand years, he said that in the process of human ingots evolution, genes carry selfish genetic code, so people are naturally selfish, unlimited grabbing of the earth's resources, at the current rate, human beings are likely to disappear in two hundred years. Humanity is gone, and the Earth still exists in this universe, and maybe when it hits a black hole, the Earth will be finished.

Question 2: How many years does the earth live? The earth has lived for 4.6 billion years, according to astronomers, the earth has entered middle and old age, it just turns and turns, 4.6 billion years, also tired, o(o, everything is born and dies, this planet will not be an exception, she will be 20-3 billion years later, it will really disappear, 2012 seems to be a little early, question three: does the earth have a lifespan? How many years of life remain? Five billion years is the remaining lifespan of the sun.

It doesn't matter how many years the earth has to live, the important thing is that there should be no hundreds of millions of human beings, because every tens of millions of years there will be major events, such as the conversion of the geomagnetic poles. In addition, every 200 million years, the solar system will also be significantly affected by alien asteroids, such as dinosaurs, etc., will become extinct at that time.

However, human technology is developing rapidly, and it is hoped that in the near future we will be able to discover other places suitable for human survival, and of course, there may be ways to avoid major disasters.

In addition, everyone's life expectancy is only 100 years, we do our own things in our own posts, and our children and grandchildren have their own children and grandchildren, which is not something that people of our age worry about.

Question 4: How many years does the earth live? The life span of the earth is about 10 billion years, that is to say, the earth will die out in four or five billion years, and the reason for the finch burning is due to the end of the sun's hydrogen fusion and the beginning of helium fusion, which is the sun turning into a red giant, swallowing Mercury, Venus, and the earth, and only Mars survives among the terrestrial planets.

Hope it helps, hopefully thank you.

Question 5: How long is the life span of the earth? The lifespan of the Earth lies in the longevity of the Sun, which is now in the main-sequence phase, which is 5 billion years old, and it is estimated that the Sun can last up to 10 billion years in the main-sequence stage.

Eventually, when the Sun reaches the red giant stage, it becomes the final white dwarf, and then expands until it swallows up the Earth, which is the end of the Earth.

Question 6: How long does the earth have to live? If there were no outside interference, the earth would go on forever.

The sun is gone, and the earth is gone. If the sun is gone and there is an artificial sun to replace it, the earth is still blind and the pie will continue to turn. In short, rocky planets like the Earth will not die out on their own, and they will only die out under the influence of external factors.

The lifespan of the Earth is about 9.6 billion years. Through data comparison, scientists have found that for the next 2 billion years, the earth will still be suitable for human life, which is a bit surprising, which is fortunate for humans. There are countless possibilities for 2 billion years, and with the rapid development of science, people may find a second home in space for human beings to move to.

The history of the Earth's generationAccording to scientific records, the birth of the earth was about 4.6 billion years ago, the original earth is different from today, the original earth was formed as a blazing fireball, and there was no life at all. It was during the second evolution of the earth that some primitive ecosystems were formed.

According to the history of the Earth, the inference of the continental drift hypothesis shows that in the second stage of the Earth's development, the Earth continuously released energy outward, forming large-scale water vapor, carbon dioxide and other substances, and finally evolved into the original atmosphere.
