For the energy of the earth, it is nothing more than mass and heat. It is said that the earth receives about 10 tons of cosmic dust every day, which is several orders of magnitude larger than those satellites and probes that have only been available in recent decades.
And fossil fuels and photosynthesis or something, I don't think it makes any practical sense for this issue. To put it simply, the heat energy of the earth is the sun. And in addition to the sun, the earth is also a heat source that cannot be ignored relative to the 3k microwave background radiation, although it has not been calculated, but I think the earth loses more heat than the heat from the sun, as nwwind said.
Taken together, for the earth as a whole, the energy is gradually increasing. After all, in the macrocosm, quality is the truth.
By the way, thermal radiation and heat transfer are two separate things, not to be confused.
-
If the Earth's energy is getting higher and higher, then the Earth will be warmer and hotter over hundreds of millions of years, which is not the case, which means that the energy has not changed much. The Earth is in a process of dynamic equilibrium. That is, most of the heat that is absorbed is reflected back into space.
As for the theory of relativity, the matter of the earth basking in the sun is not yet at the theoretical height of the theory of relativity. That's when it comes to nuclear reactions.

You didn't understand what Jokingblack said.
He is very right, he has already said that the key to biotransformation is photosynthesis, how is the energy conversion within the earth? ? What is photosynthesis, which is the way plants conserve energy, and then convert it into our energy through the food chain, not internal energy conversion...
How can you be so sure that thermal radiation must be an exchange of energy between the surface and the atmosphere? The atmosphere also communicates energy with outer space,。。
For the entire Earth system, it is not energy constant.
I'll just say a little bit, light hitting something black is enough to convert light energy into heat,。。 The energy exchange between the earth and outer space is very complex, and it is absolutely impossible to equilibrium, energy is preserved on the earth in various forms, not that energy can be preserved on the earth through the mass-energy conversion of nuclear reactions, and chemical reactions can conserve energy in a complex material structure.
As Jokingblack said, the general trend is that the earth is getting hotter and hotter, and all kinds of signs can show it, you can just look for examples.

The Earth is essentially in thermal equilibrium as a celestial body. Constantly absorbing sunlight (plus the energy generated inside), in addition to consuming part of it internally, it also radiates out a part, and the two are basically the same.
-
It should all be...
Now too much energy is converted to Earth.!...
-
How much energy is added is not much.
-
The vast majority of the energy on Earth is greater than that of the Sun. The sun is the mother of all things, the "source" of energy, it provides the earth with a huge amount of energy, energy in the form of electromagnetic waves to radiate around, this phenomenon is called solar radiation.
Earth's energy** compositionAccording to Einstein's mass-energy equation, processes such as the collapse of matter will lose mass and release energy, and some processes will release gravitational potential energy (potential energy is equivalent to stored energy). The earth's energy includes solar energy and energy provided by the earth itself, such as heat energy produced by the decay of radioactive elements.
Most people accept that the universe is from the beginning, and then the universe begins to produce various elements and substances, and this process can release huge energy.

How much energy does the earth have? Yes: How much energy does the Ground Mask Fiber Laughing Ball have?
The average amount of heat transferred from the Earth's interior is seconds per square centimeter, and based on the number of seconds in a year and the total surface area of the Earth, it can be calculated that the amount of heat transferred from the Earth's interior by heat conduction should be in the number of calories or joules in a year.

If only the rotational motion is considered (translational motion is not considered).A simple estimate is given here.
Rotational energy e=(1 2) i 2
i is the moment of inertia.
is the angular velocity. The moment of inertia of the sphere i=(2 5) m r 2 earth mass m=
Earth's radius r= km
The Earth's autobiographical angular velocity =2 t=2 (24*3600) so rotational energy: (keep 3 significant digits).
e=(1/2) i ω^2=(1/2)*(2/5)* 2π/(24*3600))^2= j

(1) Absorb light energy from the sun during the day, the radiation intensity of the sun is about 1300 watts per square meter when the sun is illuminated vertically, and most of this energy is absorbed by the ground and the atmosphere into heat energy, and some is absorbed by the photosynthesis of plants, and part is reflected back into space by the atmosphere.
2) At night, the Earth's sunny side is in dark interstellar space, and the temperature of interstellar space is about -270, so the Earth's sunny side will radiate energy into interstellar space.
In this way, while absorbing solar energy, it radiates heat energy into the universe, and there are gains and losses, so the average temperature of the earth's surface remains roughly the same.
In fact, the average temperature of the earth's surface is not constant, because human industrial activities produce a large amount of carbon dioxide and other heat-absorbing gases, which absorb a large amount of solar energy, which increases the average temperature of the earth's surface, causing the greenhouse effect.
As a direct result of the greenhouse effect, the melting of glaciers at the poles has led to a rise in global sea levels, as well as the polarization of extremely cold and extremely hot weather in habitable zones across the globe.
The average temperature of the Earth's surface is currently about 14, and meteorologists have observed that the average temperature of the Earth's surface has risen by about 100 meters, and the sea level has risen by meters, and the rate of increase will accelerate in the future.
Moreover, at present, our sun is in the prime of life of the main sequence star in the process of star evolution, the internal temperature of the sun is gradually increasing, and the radiation intensity of the surface of the sun is also increasing, about 10% every 1 billion years.
So in the distant future, solar radiation will gradually increase, and the Earth's surface temperature will continue to increase until it exceeds the limit of life.

The vast majority of the energy required by humans comes directly or indirectly from the sun in the energy (mainly solar energy) from the Earth's outer celestial bodies. It is the various plants that convert solar energy into chemical energy through photosynthesis and store it in the plant. Fossil fuels such as coal, oil, and natural gas were also formed by ancient plants and animals buried in the ground over a long geological time.
They are essentially solar energy fixed by ancient organisms. In addition, hydropower, wind energy, wave energy, ocean current energy, etc. are also converted from solar energy.
The energy contained in the earth itself usually refers to the energy related to the thermal energy in the earth's interior and the energy related to the nuclear reactions of atoms.
The energy associated with the thermal energy in the Earth's interior, we call it geothermal energy. Hot springs and lava erupted by volcanic eruptions are manifestations of geothermal energy. The earth can be divided into three layers: the crust, the mantle and the core, and it is a large thermal reservoir.
The Earth's crust is a layer of the Earth's surface, generally ranging from a few kilometers to 70 kilometers thick. Underneath the earth's crust is the mantle, which is mostly molten magma with a thickness of 2,900 kilometers. Volcanic eruptions are usually eruptions of this part of the magma.
The interior of the earth is the core of the earth, and the temperature of the core center of the earth is 2000 degrees. It can be seen that the earth's geothermal resources are also very large.
The energy associated with nuclear reactions is precisely the nuclear energy that this book is going to describe. When the structure of the atomic nucleus changes, it can release a large amount of energy, which is called nuclear energy, referred to as nuclear energy, commonly known as atomic energy. It comes from the nuclear fission energy resources stored in the earth's crust when the uranium, plutonium and other fission reactions occur, and the nuclear fusion energy resources stored in the ocean when the deuterium, tritium, lithium and other nuclear fusion energy resources occur when the fusion reaction occurs.
These substances release energy when a nuclear reaction takes place. At present, the largest use of nuclear energy is to generate electricity. In addition, it can also be used as other types of power sources, heat sources, etc.
Energy from the gravitational pull of the planet refers to the energy formed as a result of the interaction of the Earth with celestial bodies such as the Moon and the Sun. The regular movement between the earth, the moon and the sun causes periodic changes in relative positions, and the gravitational force between them changes accordingly causes the sea water to rise and fall and form tidal energy. The amount of tidal energy is small compared to the two types of energy mentioned above.
The world's tidal energy is converted into about 3 billion tons of coal per year, and the actual usability is only in the shallow sea, which can be converted into about 60 million tons of coal per year.

Energy here refers to the amount of energy that humans can use**.
At present, the energy sources available to human beings mainly include oil, coal, natural gas, wind and hydroelectric power, animal and plant food, geothermal, nuclear energy, etc. With the exception of geothermal and nuclear energy, most of the energy** comes from the sun.
The animal and plant food that humans rely on for survival obviously comes from the photosynthesis of plants on the earth, and the photosynthesis of plants converts solar energy into chemical energy and fixes it in the organic matter of plants, and animals eat plants and then transfer the energy to the animals. Oil, coal, and natural gas are believed to be formed by animals and plants through a certain mechanism over 10,000 years, so the combustion energy contained in them is essentially the same as solar energy.
When sunlight shines on the earth, any material on the earth's surface can absorb its radiant energy, thereby increasing the temperature, causing changes in air temperature, ocean temperature difference, water evaporation and condensation, thus forming climate change such as air flow, ocean currents, and rainfall. Therefore, wind power, ocean current power, river flow drop power, etc., all come from solar energy in the final analysis.
The electricity generated by wind power and hydropower is also derived from solar energy. All forms of energy on Earth are converted from solar energy through different mechanisms.
-
Because there is no other star other than the sun that can shine and heat to provide energy for other planets, I think this is the main reason why the earth's energy is higher than that of the sun.
-
Because the sun is the only planet in the solar system that has a heating phenomenon, most of the thermal energy on the earth comes from the sun.
-
Because sunlight helps plants to photosynthesize, it is the most important energy for all living things on Earth** (there is no one), and the sun existed long before the earth existed.
-
Because the sun's light and heat absorb the growth of all things bring sunlight and energy, so it is said. Most of the energy on the earth is the sun, and the sun is the source of the growth of all things.
-
Because the Sun is the closest star to the Earth, it provides light and heat to promote the growth of all things on Earth, so it can be said that most of the Earth's energy comes from the Sun.
-
Because without sunlight the whole earth would become dark, plants would not be able to photosynthesize, oxygen would not be produced, crops would not be harvested, and animals would get sick without light.
-
Sunlight and radiation have the meaning of coexistence for all living plants on the earth, and if the sunlight changes, it will also affect people's lives.
-
If there is no sun, plants cannot grow, what people eat is not guaranteed, and everything is inseparable from the sun.
-
Because a lot of energy on the earth is due to solar radiation, without the sun, there will be no lot of energy on the earth!
-
Because the sun can put a lot of light and heat energy, it is precisely the most important thing for the people of the earth to be glorious and lively, heat energy can bring us warmth, bring a bumper harvest, bring hope, and light energy can bring us a steady stream of energy and development, so the sun is the source of energy on the earth.
-
Because the energy of the sun can really be converted into a lot of things, and if there is no sun, there will be a lot less things on our map, so most of the energy on the earth comes from the sun.
-
Because generally speaking, energy is converted from a high energy level to a low energy level, and the closest to our earth is the sun.
-
Because most of the earth's energy is converted from the sun's solar energy, and most of the energy we use is also converted by solar energy, so the earth's energy is mostly more than the sun.
-
Most of the earth's energy is more than the sun, the most direct is solar energy, other wind energy, water energy, all kinds of fossil energy are derived from the sun, the earth is not the sun's energy only nuclear energy, tidal energy and a few others.
-
The vast majority of the energy on the earth comes from the sun, and the energy of the sun spreads to the earth in the form of light to provide the energy needed for the growth of all things on the earth.
-
Sunlight and heat provide the conditions for the growth of plants on the earth, as well as energy and materials for all animals, including humans.
-
The energy inside the earth did not erupt, and if it did, humanity would perish. So at present, the energy on the surface of the earth is all external energy, and the closest energy source to us is the sun, and only the energy of the sun can be effectively received by the earth.
This question relates to the specific legal process and the specifics of the divorce case, so there is no one definitive answer. Usually, litigated divorces take a certain amount of time to be heard and adjudicated. Generally speaking, according to the provisions of the Civil Procedure Law, the time limit for the first instance is three months according to the summary procedure, six months according to the ordinary procedure, and three months for the second instance. >>>More
Personally, I think that Deyun Club is not something that can be supported by one person, and it is not the credit of only one person, Deyun Club is actually a brand, and it is impossible for a name to be good to Zhang Yunlei.
Especially in the urban area, there are more and more cars on the road, and pedestrians are also dense, so it is inevitable to be anxious and press more horns, one is afraid that they have not been able to pass after the traffic light, and the other is that sometimes they have to honk, such as the car in front of them suddenly does not turn on the turn signal to cut the line, or the car in front of the car does not see that the red light has turned red, etc., all make the driver helpless to honk.
When will this vice be ended? Chinese like to compare, good face, some families to marry their children basically ruined. A little better, after getting married, there is not much savings left, it is too unnecessary, I think this country should force a limit of a certain amount.
