What kind of era was the Carboniferous Period? Why was the oxygen level so high during that period?

Because it was the most humid and hot period on the planet, the vegetation flourished, and it was also the time when plants developed from algae, ferns, gymnosperms, which also provided abundant food for all kinds of animals.

The Carboniferous period was the era when life on the earth was very prosperous, especially ferns and amphibians were very prosperous, because plants appeared on land first, and there was a lack of animals to climb on land, photosynthesis led to an increase in the oxygen content of the earth, and there was no behavior of eating plants, resulting in the earth producing more oxygen, and there was a lack of animals that consumed oxygen.

It was a period with a lot of huge flora and fauna, because there were a lot of plants at that time, and these plants absorbed carbon dioxide from the earth, released oxygen, and consumed very little oxygen, so the oxygen content was very high.

The Carboniferous period is a geological time. The Carboniferous period is about 286 million to 360 million years ago, and it can be divided into two periods: the First Carboniferous (also known as the Mississippi, 320 million to 360 million years ago) and the Post-Carboniferous (also known as the Pennsylvanian, 2860 million to 320 million years ago).

The carboniferous period is the fifth epoch of the ancient tung royal leakage era, which began about 100 million to 100 million years ago and continued to rot for 65 million years. During the Carboniferous period, the land area continued to increase, and terrestrial life developed unprecedentedly. The climate was warm and humid, with swamps all over the place.

Large-scale forests appeared on the continent, creating favorable conditions for the formation of coal and demolishing towns.

Because of the collapse and fire, the rainforest collapsed, which in turn led to the end of the Giant Insect Age. Combustion requires the consumption of a large amount of oxygen and the release of a large amount of carbon dioxide, so in the late Carboniferous period, the concentration of carbon dioxide in the atmosphere was nearly three times that of the current carbon oxide concentration in Ershan. This is the reason for the continuous decrease in oxygen levels during the late Carboniferous period.

The decline in oxygen levels in the late Carboniferous period was greatly related to a major event, the Carboniferous mass extinction. This extinction event occurred about 100 million years ago. It was because of the fire that the rainforest collapsed, which in turn led to the end of the Age of the Giant Bugs.

Of course, volcanic eruptions and magmatic activity are just one of the scientifically inferred good celery.

This is because the number of plants is decreasing, and so is the ease of nutrition.

What is the time of the Carboniferous Slow Erection when the land is disturbed?

Carboniferous; It got its name due to the abundance of coal in the formations formed during this period.

It is a representative period of great prosperity in the plant world. It is the fifth period of the Paleozoic Era, which began 100 million years ago and lasted for about 65 million years.

The Carboniferous period is called "the era of giant insects", because the model book is that the atmospheric oxygen content was very high at that time, and the insects grew very large.

Because the earth's animals began to reproduce and develop in large numbers from the Carboniferous period onwards, they began to consume oxygen, so the oxygen density has been decreasing.

Because during the Carboniferous period, plants began to appear on the earth, causing oxygen concentrations to rise dramatically, while after the Carboniferous period, there were no large-scale plants, so the oxygen concentration has been declining since then.

The main reason is that there are more and more plants on the earth, and plants absorb this oxygen.

1 Some studies believe that the period with the highest proportion of oxygen in the atmosphere in all the history of the earth may be from the end of the Carboniferous period to the beginning of the Permian, or the peak of the Carboniferous period, about 300 million years. Up to 35%.

For more than two billion years in the early days of the Earth's formation, the Earth's atmosphere was in a state of negative oxygen, which may be related to the limited oxygen consumption by lava cooling. By 2.4 billion years ago, there was a "big oxygen event" on Earth, and the oxygen content in the atmosphere reached 1-3%. Some studies suggest that it may be related to stromatolite development.

Since then, this proportion of low oxygen has been maintained for nearly two billion years until 7-600 million years ago, during which time, about the end of the "snowball Earth" period, another large-scale "oxygen-making event" occurred, and it is currently speculated that the continents are generally covered with shallow sea wetlands, and cyanobacteria multiply rapidly, so that the proportion of oxygen has risen from 1-3% to about 10-12%. The increase in oxygen content led to the "Ediacaran mollusc flourish", which in turn led to the "Cambrian explosion". But at that time, the proportion of carbon dioxide in the atmosphere was higher, the climate was warm, the continents were clustered near the equator, the tall ferns grew luxuriantly, the density between plants was extremely high, and the distance between trees was even less than 30 centimeters, and under photosynthesis, plants grew to consume carbon dioxide and spit out a lot of oxygen.

Due to the formation of lignin, the fungi that decompose plants have not yet appeared, resulting in a large amount of carbon being solidified and deposited underground along with the life cycle of the plant, making possible the formation of high-quality coal mines in the Carboniferous period thereafter. At the same time, the proportion of carbon dioxide in the atmosphere decreased, and the proportion of oxygen increased significantly, reaching the highest proportion of atmospheric oxygen in the history of the earth in the late Carboniferous period.

First of all, it was not from the Carboniferous period, when the concentration of oxygen on Earth began to decrease, but from the Carboniferous period, the concentration of oxygen on the Earth suddenly skyrocketed. It is believed that the Permian after the Carboniferous period gradually began to decline in oxygen concentrations. Because during the Carboniferous period, the plants on the earth flourished, and they produced oxygen to unprecedented heights.

Carboniferous oxygen concentrations are highAnd because there were not many large herbivores in the Carboniferous period, this also created a very good living environment for plants at that time, so that plants could better absorb carbon dioxide and produce oxygen, so this made the oxygen concentration on the earth at that time reach an unprecedented height. And because the overall oxygen concentration on the earth is high, many giant insects were bred, such as giant dragonflies, spiders, and horses, etc., and the insects at that time were so large that they were like today's cars.

At the end of the Carboniferous Period, the Earth ushered in a large ice age, which destroyed many of the Earth's tropical rainforests, so the oxygen concentration produced by the tropical rainforests continued to decline, which is why the oxygen concentration on the Earth continued to decline after the Carboniferous Period. It is precisely because the oxygen concentration on the earth continues to decline that we do not see dragonflies the size of cars now.

Mineral resources are a product of the Carboniferous periodMoreover, the coal mines, oil and other mineral resources we dig now are all products left over from the Carboniferous period, because only in that era could so many plants be buried in the ground, and after many years of geological changes, they became the necessary energy materials for our people now. Such energy materials are not inexhaustible and endless, it has a certain amount of storage, so we must develop new energy for the development of human beings in the future. Reduce the use of such energy sources.

Although the current oxygen concentration on our earth is not as high as the oxygen concentration in the Carboniferous period, the concentration of carbon dioxide on our earth is rising, causing a greenhouse effect, which is very harmful to our human living environment, so we must unite to reduce carbon dioxide emissions, because this will harm our own environment. Every substance exists on the earth for its own reasons, if a substance suddenly continues to rise, then it will inevitably lead to the disorder of the entire ecosystem, and ultimately the damage is still the organisms living on the earth, so we must stabilize the ecological balance on the earth.

Obviously, because of the increase in the number of plants that absorb oxygen and the evolution of organisms, every factor of the environment affects the development of the earth all the time.

In the late Carboniferous period, the decrease in carbon dioxide led to a decrease in the photosynthesis capacity of algae plants, and oxygen consumption increased, so the concentration of oxygen in the atmosphere began to decrease.

Because life appeared on the earth from the Carboniferous period, it began to consume oxygen, causing the oxygen concentration to begin to decline.
