How did coal mines come about?In fact, the formation of coal mines is closely related to plant remains and crustal movements.
First, let's learn about plant remains. On Earth, plant remains are one of the main coals. After a long period of decay and decomposition underground, these plant remains gradually formed coal seams. Among them, the most important plant remains are ferns, because they are relatively large in structural composition and quantity, which provide a rich material basis for the formation of coal.
Next, let's take a look at the movement of the earth's crust. Crustal motion refers to the movement of tectonic plates on the Earth, which are constantly moving and deforming. These movements led to changes in the terrain and the formation of mountain ranges. When these mountains formed, they buried plant remains in the ground, creating coal seams. Over time, these seams changed and evolved over millions of years to form the coal mine we mine today.
In addition to plant remains and crustal movements, climatic and geological conditions also had an important impact on the formation of coal mines. In warm and humid climates, plants grow luxuriantly, providing more material basis for the formation of coal. At the same time, geologically, some specific rock and soil types also provide favorable conditions for the formation of coal.
In conclusion, the formation of coal mines is the result of a combination of factors. It requires the abundance of plant remains**, the constant action of crustal movements, and suitable climatic and geological conditions. It is the interplay of these factors that makes it possible to mine such abundant coal resources now.
