Explain why coal finds physiological phenomena from the sea

Coal is an organic biological rock formed by the biochemical action of ancient plant remains submerged in the water, and then covered by the stratum and formed by physicochemical and chemical reactions.

Coal is the remains of ancient organic matter (mainly plants), formed by biological and chemical metamorphism. It can be roughly divided into two stages, the first stage is the peat stage, that is, the transformation from plants to peat. When the plant dies and accumulates in swamps and oceans filled with water, at first the oxygen in the water is insufficient, and then the air is isolated under the surface of the water, and under the action of bacteria, the various parts of the plant are constantly decomposed, interacting, and finally the remains of the plant become brown or black-brown silt substance, which is peat.

This process is called the peat process. This stage requires a long period of geological history and takes millions of years. In the second stage, peat is converted into lignite, lignite is converted into bituminous coal, and bituminous coal is converted into anthracite.

When the peat layer is formed. Water often washes over the low-lying areas of the continent, bringing with it a large amount of sand and stones, which gradually form rock layers (called roofs) in the quagmire layers. The peat layer buried under the roof underneath the mud layer under the roof under the pressure of the roof rock layer has undergone a series of changes such as compression, water loss, colloidal aging, induration, etc., and its chemical composition has also undergone slow changes, gradually turning into a larger specific gravity, denser black-brown lignite.

When the roof is gradually thickened, the static pressure of the roof gradually increases, and the temperature in the coal seam gradually increases, the coal quality changes, and gradually changes from diagenesis to metamorphism mainly affected by temperature. In this way, lignite gradually turned into bituminous coal and anthracite. If there is a higher temperature, it may eventually turn into graphite.

Coal formation must meet four prerequisites: (1) plant conditions. (2) Climatic conditions. (3) Geographical conditions. (4) Crustal movement conditions.

There are two possibilities, one is that plants on the continent were deposited in the early continent to form a medium, and the other is that plants in the ocean were formed over a long period of time due to river alluvium.

It turned out to be continents, then oceans.

Nautical miles are defined in terms of the circumference of the Earth. If you split the Earth in half along the equator, you can consider the equator of one of the hemispheres as a circle. Then divide it into 360 degrees.

Then divide each degree into 60 points. Every minute of the arc on Earth is one nautical mile. At present, this unit of measurement has been adopted by countries around the world.

One nautical mile is equal to 1,852 meters, or kilometers. In the British system of measurement, one nautical mile is equal to a mile, or 6,076 feet. If you go around the Earth along the equator, you would need to walk (360*60) 21,600 nautical miles, or 24,857 miles, or 40,003 kilometers.

Give people roses, leave a lingering fragrance in your hands, and hope to give me a good review Thank you

In our country, 1 nautical mile is equal to a kilometer. However, this does not apply to all parts of the world. The length of the nautical mile is not fixed, and varies from country to country.

This is because, in navigation, the length of the L arc of the Earth's meridian circle is 1 nautical mile (that is, the length of the meridian corresponding to 1 degree of latitude). However, since the Earth is not a standard sphere, the length of the arc of the meridian circle varies at different latitudes.

This results in the longest and shortest nautical miles. The shortest nautical mile is at the equator, l nautical mile = 1843 meters. The longest nautical miles are at the North and South Poles, 1 nautical mile = 1862 meters.

In addition, in the old days, "nautical" was written as "li", which has now been abolished. At sea, the speed of 1 knot per hour is called 1 "knot".

Nautical mile refers to the distance in the sea, which is equivalent to the distance of land.

However, this does not apply to all parts of the world. The length of the nautical mile is not fixed, and different countries use different lengths to burn carefully. This is because:

Human beings are first living beings, and then higher animals, what classes and genera are there.

If it is a living organism, it needs to reproduce, which is the nature determined by the genes suitable for competition that have been eliminated and screened out for thousands of years, and it is not difficult to understand the instinct to produce attraction, which is the premise of human existence.

As for homosexuality, it can be understood as a manifestation of genetic tolerance, human genes often have some "mistakes" and mutations, those who are suitable for survival will reproduce and continue to retain, and those who are not suitable for existence will naturally perish, so homosexuality has always existed since ancient times, and it must have the value and meaning of existence, whether it is genetically given or for other reasons.

When two adult animals such as white rats are kept in captivity alone, they usually mate without a teacher due to their respective female and androgenic factors. This is a miraculous ability given by nature.

From a single cell to a mammal, the eternal theme of life is self-reproduction and species continuation. Among them, there is the scientific principle of universal adaptation, the law of nature.

Therefore, the great psychologist Sigmund Freud proposed that human instinct is sexuality, because human beings are also animals, animals are creatures, organisms are the carriers of life, and the meaning of life is the continuation of species.

Of course, humans are higher animals, and ordinary animals will not think about such a problem as yours. It's often impulsive, and things are done.

If an organism does not have the property of attracting each other, then it is destined to be non-existent.

When a living organism reaches a certain age, the body secretes hormones. The behavior of living organisms is regulated by both nerves and body fluids. When someone of the opposite sex appears, you judge the appearance of the opposite sex and then understand what he or she means.

If he or she has something that attracts you, in your mind you like him or her, you also secrete hormones in your body. I read some magazines that American scientists have studied men and women who love each other, and when they are in love, they have a certain hormone in their blood that is obviously high (as if it is a hormone). But after a few years of marriage, the hormone returned to normal levels, and the heat between them decreased.

What keeps them together is not a passionate relationship, but responsibility and affection.

"Opposites attract" is an instinct to attract each other. Your happiness, pleasure, pain, and so on are all a combination of your subjective consciousness and the hormonal regulation of your humility.

It may be due to the interaction of the X and Y chromosomes.

Biological instinct, pure nature

The molecules are moving irregularly and in any direction, including on the surface of the wall or even inside the wall (there are voids in the wall molecules).

Hah, I think it's like the bright light is too much of an eye that makes your nose itch and you can sneeze out

Bright light causes itching in the nose.
