How is the coal seam more than 100 meters thick formed? In ancient times, were there so many plants on earth?

In the process of our production and life, we all need to use some corresponding resources. For the earth, it not only breeds life, but also gives human beings abundant resources to use. Among them, coal resources are very important! Now the coal seams found in some places can reach more than 100 meters, and the mainstream view is that they were formed by plants in ancient times, so were there so many plants on the earth in ancient times?

For a planet like the earth, the crust is very thick, and there are many underground resources in it, including oil and various metal raw materials, etc. Now, with the needs of people's industrial production, it also begins The demand for these resources is increasing.

At first, people started mining after discovering such underground resources, but now facing the problem of resource depletion, people have also launched a heated discussion, and this is not alarmist.

You must know that many of the resources we use today are actually non-renewable, such as coal and oil resources. These two substances can only be gradually formed after a long geological evolution. , maybe we have no way to have such resources anymore.

Among them, coal, as a main resource, is of great significance in life, and has a wide range of applications in industrial smelting and people's heating in peacetime.

And unlike some metal deposits, many of these non-renewable resources are transformed from ancient organic matter. Coal is one of them. After the death of ancient animals, plants or microorganisms, their bones are in this layer. These resources were formed through deposition and evolution.

For coal, it has always been thought that it was formed by the accumulation of ancient plants, which left stable carbon elements under the pressure of the formation, forming the coal we see today.

While scientists are studying these coals, they can also find that there are some lines and traces left by plants in ancient times, so they are even more convinced that the coals are formed by these ancient plants.

In the speculation of scientists, they believe that these ancient creatures, especially some plants, merged with the soil after withering, and went through a long and complex transformation process with the movement of the crust, first forming a peat layer, and finally transforming into lignite , bituminous and anthracite.

On the whole, the quality of anthracite is the best among them, with less impurities, less smoke, and can be fully burned, relatively speaking, the pollution will be less, and after the coal is mined, it has to go through the process of coal washing to remove it. some impurities.

In the process of coal mining, sometimes the thickness and quality of coal in different places are different, and some of the coal seams can reach hundreds of meters. How did it come about?

Among them, I have to mention that the 2nd-period coal basin in Fushun, Liaoning Province, China, has a maximum thickness of 130 meters. Why are these coal seams still so thick after such a long time? Could there have been so many plants in ancient times?

This question also makes scientists feel very curious, in fact, the answer is yes!

You must know that the earth today has experienced 5 mass extinctions, and once in the Carboniferous, Permian and Jurassic periods, the overlords on the earth at that time were dinosaurs, and at that time, the atmosphere was rich in oxygen, humid climate, plants and The animals are large and numerous.

In such a period, the amount of life that the earth has nurtured is also very large, and the lush degree of plants is unimaginable today. There are many forests and plants, and it is not surprising that these coals are produced.

For these plants, their debris accumulates layer by layer to form peat layers, and then in the conditional structures with sedimentary structures, such as basins suitable for producing deep coal seams, this is because the unidirectional deposition is conducive to The accumulation of coal seams.

Coal is known as "black gold" and plays a very important role in the development of modern industry. Moreover, China is very rich in coal resources, and it is also the country with the highest coal production in the world. However, you must know that coal is not inexhaustible. Inexhaustible.

After all, it is a non-renewable resource, and we should try to reduce its consumption as much as possible. At the same time, it can also reduce the emission of some greenhouse gases, which plays an important role in protecting the ecological environment.

Today, there are actually many coal mines that have not been discovered by humans, waiting for us to explore further, but for this resource, we should protect it more!
