How many years does the earth live?

Scientists analyze that the Earth has been around for 4.6 billion years and will continue to last for another 5 billion years, so the Earth's lifespan is about 9.6 billion years. According to geoscientists, the Earth is at least 4.6 billion years old. The written history of mankind is only a few thousand years, and it is only a moment in the long river of the universe.

To understand the lifespan of the Earth, we must first look at the lifespan of the Sun.

The age of the Earth is commonly referred to as its astronomical age, and the current best estimate of the Earth's age is 100 million years.

According to scientists** at least 10 billion years ago.

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.

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.
