A Scientific Look at the Earth?!?! 5

Unfortunately: the premise and reasoning are incorrect.

The range of human activities is the very superficial range of the earth. If you are the Earth, "human activity" does not even pass through your epidermis, and you do not feel "human activity" at all.

In the process of turning solids into gases, humans also produce a lot of solids, and also consume the original gas (oxygen) in the atmosphere. The newly formed gases (CO2, etc.) are solidified by the surface vegetation and become solid (plants, animals, soil). In this cycle, the current direct human influence is insignificant.

But if you take into account the greenhouse effect and desertification, the problem is much more serious.

The height of man is due to evolution, and the gravitational pull of the earth has hardly changed over the past few hundred million years. At least biologically, there is no change. Gravity is a very small force.

99% of the reason is the release of pressure inside the earth's crust, and the construction of dams may be triggered by human mining in certain key locations. But it's just triggering, not causing. Therefore, the principle of water droplets is surface tension, which has nothing to do with ** at all.

Humanity has been changing the planet at an ever-increasing rate:

1.From the interior of the earth, a large amount of coal is extracted, a large amount of natural gas is extracted, and a large amount of oil is extracted. Wait a minute;

2.From the surface of the earth, a large number of trees are cut down. Wait a minute;

3.And through chemical reaction, at an unimaginable speed, these solids and liquids --- turned into gas;

So from the point of view of mathematics and physics: conservation of energy: --

The total mass of the earth has basically not changed, and if the earth is divided into the center of the sphere and the atmosphere; The center of the sphere under our feet is rapidly changing from solid to gas, and it can be calculated and verified that the mass of the center of the sphere is decreasing (because a large number of the center of the sphere is converted into gaseous state and injected into the gas layer), so the atmosphere is increasing rapidly, if the "coefficient" Earth solid Earth gas; Then this "coefficient" of the earth is decreasing, from the physical astrology, our earth is growing, that is, the volume is getting bigger, when most of the land under our feet is converted into gas, the earth will be amazingly large;

Can the above changes explain these problems:

1.Because the mass of the earth under our feet is decreasing, the gravitational pull of the earth on us humans is decreasing, so the height of humans will become higher and taller (mainly reflected in teenagers);

2.Because of the exploitation of resources, the interior of the earth is empty, and from the principle of water droplets, the earth has to collapse (that is, **) to maintain equilibrium.

Water Drop Principle: Do you know why water droplets are round, yes, this is it).

Of course, there are many problems: what seems to be a natural disaster is actually for a reason;

Is that reasonable?

Question Supplement: Supplement:

But the fact is that the earth has its own circulatory system, for example, this circulatory system used to be balanced, so while human beings convert a large number of solid and liquid substances into gases through chemical reactions, they are also converting a large number of trees and grasslands. > the destruction of the medium of gas conversion of solid and liquid in this circulation system is equivalent to accelerating the conversion of solid into > gas, and at the same time slowing down the gas conversion > solid and liquid;

So in general, there are fewer solids, less liquids, more gases, smaller balls under your feet (mass, volume), and more atmosphere;

We have cars, power stations, there are **. and so on, the way and speed of these conversion of solid liquid into gas is far greater than the way and speed of gas returning to solid and liquid;

There are many specific times, such as 512 Wenchuan **, Tangshan **, volcanic eruptions, and so on.

You are a little whimsical, our current influence on the earth is only in the part above the crust, and it does not penetrate deep into the interior of the earth, and the effect on height, ** you are talking about does not exist at all.

There are two kinds of living things, one is visible and tangible, and the other is invisible and intangible, and living things are multiplying for generations, and the reproduction of human beings has brought development and disaster to the earth, while the reproduction of animals and plants has brought vitality to the earth

Sometimes I wish I was an animal, I could live in a dense forest away from the hustle and bustle of the city, at least the animal would not make harmful garbage everywhere to pollute the environment, but the forest is no longer the peaceful paradise of the past

It is said that human society is a society of spiritual civilization, but how many of the things done by today's human society are civilized, and there is dirt everywhere I always feel that I am living in a messy human society

There are both positive and negative aspects to everything, and being civilized also means that there is a relative need to sacrifice something

Since the beginning of the development of human society, hundreds of animals and plants in the world have been tragically extinct Human beings are occupying their habitats in order to live As the saying goes: the strong survive For animals and plants, human beings are the strongest and strongest in the world

I often think about the diseases that have brought people great fear in recent years: AIDS, foot-and-mouth disease, SARS, avian influenza, leukemia ......Aren't these the consequences of human beings' own making? I really want to look up to the sky and smile, it's really self-defeating!

The results are ironic, but they are very real

Originally, these have brought great harm to human beings, but human beings themselves have not seen clearly and become more wanton Cannibalism Don't feel Cannibalism This word is used too much, and don't think I'm radical TV news often reports that so-and-so black processing point produces inferior food, black-hearted producers, in order to earn personal profits, add excessive amounts of chemicals into the food people eat, use excessive Sudan red castration to make red duck eggs, and then there is sick and dead pork, and use hair to make soy sauce, Profiteers put the lives and deaths of others aside for their own benefit, so people are selfish

I hope that in the future, I will not become colorful in the big dye vat of society, I am me, don't change my nature for the sake of profit!

I also hope that human beings will take action, raise their consciousness, protect the earth, and protect the homeland on which all kinds of creatures depend! Do you remember the tsunami that occurred all over Asia, if people's awareness is not raised, I am afraid that in the future, we will face more disasters and losses, and in another 20 years, mankind will taste more disasters that are difficult to describe in words!

To protect the environment is to protect yourself, and to love others is to take care of yourself! Let's communicate with love! Finally, I quote a three-character scripture to end the article, although I will memorize it when I am a child, but how many people are born when they grow up At the beginning of people, the nature is good, and being kind to others is to be kind!

Don't slack off, act fast! (All of the above is a personal opinion).

Earth is one of the nine planets in the solar system, and is the third planet in descending order from closest to farthest from the sun. It has a natural satellite --- the Moon, which form a celestial system --- the Earth-Moon system.

The Earth rotates from west to east while revolving around the Sun. The combination of the Earth's rotation and its orbital motion produces the alternation of day and night and the changing seasons on Earth. The speed at which the Earth rotates is uneven.

At the same time, due to the gravitational effects of the sun, moon and planets, as well as the various effects of the atmosphere, oceans and internal materials of the earth, the direction of the earth's axis of rotation in space and the earth itself must change. The inertial centrifugal force generated by the rotation of the earth causes the spherical earth to gradually expand from the poles to the equator, becoming the current slightly flattened spheroid, with a polar radius about 21 kilometers shorter than the equatorial radius.

The Earth as seen by the Apollo spacecraft The Earth as seen by the Apollo spacecraft The Earth rises above the horizon of the Moon, and the Earth can be seen as consisting of a series of concentric layers. The Earth's interior has a core, mantle, and crust structure. The Earth's exterior has a hydrosphere and atmosphere, as well as a magnetosphere, forming a coat that surrounds the solid Earth.

Earth, as a planet, originated from the primordial solar nebula 4.6 billion years ago.

The horizontal mountain is absolutely amusing, and the vertical wisdom is relative.

Earth Earth is one of the eight planets of the solar system, and its international name is "Gaia" (Gaia), the god of the earth in Greek mythology, the most respected and illustrious god of all gods. It is the earliest god to appear in Greek mythology, born by Caius (Chaos) at the beginning of the world. She was the grandmother of Zeus, Gaia gave birth to her brother Ouranos or Uranus, and married him to give birth to six males and six females, twelve Titans and three Cyclops and three hundred-armed Titans, the beginning of the world, and all the gods are her descendants.

To this day, Westerners still often refer to the earth as "Gaia". In order of being closest to the sun, it is the third. It has a natural moon--- the Moon, which form a celestial system --- the Earth-Moon system.

The Earth rotates from west to east while revolving around the Sun. The combination of the Earth's rotation and its orbital motion gives it the day-night alternation and the seasons on Earth (the speed of the Earth's rotation and revolution is uneven). At the same time, due to the gravitational influence of the sun, the moon, and nearby planets, as well as the earth's atmosphere, oceans, and internal materials, the direction of the earth's axis of rotation in space and the earth's body changes.

The inertial centrifugal force generated by the rotation of the Earth causes the spherical Earth to gradually expand from the poles to the equator, becoming the current slightly flattened spheroid, with a polar radius about 21 kilometers shorter than the equatorial radius. The Apollo spacecraft saw the Earth on the moon and was made up of a series of concentric layers. The Earth's interior has a core (core), mantle (mantle), and crust (crust) structures.

The Earth's outer perisphere has a hydrosphere and atmosphere, as well as a magnetosphere, forming a beautiful coat of dust that surrounds the solid Earth. Earth, as a planet, arose 5.6 billion years ago from the primordial solar nebula. Basic parameters of the earth:

Flattening Factor: Average density: g cm3 Equatorial radius:

ae = m Pole Radius: ap = m Average radius: a = m Equatorial gravitational acceleration:

ge = m2 Average angular rotation velocity: e = 10-5 radians sec Flattening rate: f =

Because the geologic dust ball is round, but you are very small on the earth, you can't see that the earth is round, but there are many phenomena that we can feel that the earth is round, for example: a ship in the distance is sailing towards the harbor, we see the mast of the ship first, and then the whole body of the ship. The earth is round, lead is hidden, but why didn't we fall from the earth?

Because the earth has a gravitational pull, limb meditation is like a magnet that draws us firmly to the earth's surface.

In the 18th century, the German philosopher Immanuel Kant put forward the hypothesis about the formation of the earth"Nebula hypothesis"。

Before the formation of the solar system, it was a nebula made up of red-hot gas. 4.6 billion years ago, when the cooling of the gas caused contraction, it caused the nebula to spin. Due to gravity, the gas and wind wind and grass contract and rotate faster, and the nebula becomes a flat disk.

We know that the washing machine used to wash clothes in modern families has a dehydrator, put wet clothes in it, and the dehydrator rotates quickly, and the moisture in the clothes will be "thrown" out, and the wet clothes become dry clothes. The force that throws water out is the force generated by the water droplets leaving the center when they move in a circular motion, which is called centrifugal force. In the same way, when a rotating nebula shrinks and rotates, and the centrifugal force of the surrounding matter exceeds the centrifugal pull of the center on it, it separates a ring.

And just like that, one ring after another was created. Eventually, the central part becomes the sun, and the surrounding rings become planets, one of which is the Earth, which was created four or five billion years ago.

At the beginning of the formation of the earth, the temperature was low, and all kinds of materials mixed together and lived in peace. Later, due to the action of radium, uranium and other radioactive materials in the earth's interior, the mountains erupted and intensified, and mountains, hills, and plains were gradually formed. Due to the irradiation of the sun, the temperature of the earth slowly rises, and the chemical action of the earth's internal materials releases a large amount of carbon dioxide, methane, nitrogen, water vapor, etc.

These gases rise to the Earth's exterior to form the atmosphere. Rainfall occurs when water vapour meets cold air currents at high altitudes. The earth is hit by a lot of rain, and it merges into oceans, lakes, and rivers in low-lying places, so that plants, animals, and humans are also there.

It took billions of years to evolve the Earth to become what it is today.
