Half of May this year has passed, and the seasonal climate is about to usher in a high temperature and rainy season. At this time of the year, high temperature brings typhoons. The rainy season challenges mankind. Rain itself is a normal atmospheric convection phenomenon. Crops need rain to ensure a good harvest, and the dry climate also needs rain to adjust.
But everything has a degree, once anything exceeds the normal level, it is not a good thing. Rain is the same. Normal rainfall will bring endless benefits to human beings and the earth’s ecology. But if it rains too long and too much, it will bring some natural disasters, such as debris flow and flood, which will bring huge losses to the earth’s ecology and people’s life and property.
So, after the rainy season comes every year, it’s good news for people in the north, because it brings benefits to the dry climate and dry crops. But for people living in the South and close to the coastal areas, it’s not a blessing, it’s a disaster. Typhoon brought a lot of rainfall to coastal areas brought floods and other natural disasters, let people feel the power of nature.
Of course, even if it rains for a long time, it won’t take more than a week. Generally speaking, it’s a very short time, and it will clear up soon. But if it’s a very long-lasting rain, such as rain lasting for millions of years, what kind of scenario will it be? Some people may say, how could the earth rain so long? If there is such a long rainfall, it is estimated that life on the earth will also end.
Since the birth of mankind, there has been no rainfall lasting for millions of years. However, through a large number of geological surveys and studies, scientists found that more than 200 million years ago, the earth might have had a rainfall lasting for more than one million years. What’s the matter? We all know that in some very arid inland areas, such as Tibet and Xinjiang, due to the lack of rainfall, a unique red sandstone will gradually form here.
This kind of red sand can be formed gradually only when there is very little rain. Normally, they will not appear in coastal areas with more rainy seasons. However, in recent decades, when geologists are exploring rocks all over the world, they find that there are sedimentary rocks formed by this red sandstone in Italy on the European continent, Argentina on the South American continent and Japan on the Pacific island.
We should know that these areas are all coastal areas. How can there be so many red sandstone and sedimentary rocks? Such a major discovery has aroused the interest of scientists, and it is possible that we will discover a major event. If widely distributed red sandstone sedimentary rocks, their formation track and appear in coastal areas, geologists believe that this is the result of rain erosion.
That is to say, a long time ago, these red sands were in the inland arid areas, and then the continuous and long rainfall washed them away and moved them to the rocky sea areas all over the world. If so, the scale and time of this rainfall will be very huge. Through computer simulation, scientists have come to a conclusion that it may be a rainfall lasting for more than one million years, and the scale is larger than our imagination.
What is the reason for such a huge rainfall? Scientists have studied the situation of the earth more than 200 million years ago and come to an initial answer. We all know that more than 200 million years ago, the earth’s continent was still a whole, not divided. We call it Pangea. At that time, the earth had only one plate continent, so the inland area of this huge plate had little rainfall, thus forming a unique red sandstone.
Later, Pangea began to break up. When the two plates pressed against each other, they would trigger volcanic eruptions, releasing a lot of carbon dioxide. As a result, Pangea began to divide, and at the same time, it also made the earth a world of volcanic eruptions, releasing a lot of carbon dioxide. As we all know, carbon dioxide is a kind of greenhouse gas. Once the content of carbon dioxide increases, the temperature of the earth will increase.
As a result, the air on the ground is heated and rises, carrying a large amount of water vapor, forming a strong convective weather and rainy season. As the temperature of the Earth continues to rise, the temperature of the ocean is also rising, so a large amount of liquid water evaporates into the atmosphere, continuously condenses, and finally forms rainfall. Thus, more than 200 million years ago, such a scenario appeared on the earth: volcanic eruptions continued, carbon dioxide increased, the ocean evaporated under the influence of high temperature, and a large amount of water vapor entered the atmosphere to form rainfall.
The falling rain is then evaporated into the atmosphere by high temperature, so a rainfall cycle is formed. And all this is caused by a large amount of carbon dioxide brought by volcanic eruption. If the volcanic eruption does not stop, such convective rainfall climate will not be able to end. However, it took a long time for Pangu continent to split into six plates, which could not be completed in a short time.
So the earth’s volcanic eruption also needs to go through a long time, and the carbon dioxide released into the atmosphere also needs a long time to come down. Therefore, the rain weather has lasted for more than one million years, which is a disaster of mass extinction. Some people may say, such a long rain, the earth can still live?
Although the rain brought a mass extinction event to the earth, the tenacity of life is beyond our imagination. Most of the creatures died out in the continuous rain, but there is a kind of creature rising from then on. They are the dinosaurs who later dominate the earth. Before the heavy rain, dinosaurs accounted for only one twentieth of spinal animals, but after the heavy rain, they even exceeded 90 percent.
I believe that friends will be afraid after they understand the rainfall lasting for more than one million years. Some people will ask: will this terrible rainfall happen in the future? Some people may say that the earth in the future will never have such natural disasters again. Is this really the case?
We need to understand that 200 million years ago, the continuous and long rainfall was caused by the rising temperature of the earth. As long as the temperature rises to a certain extent, ocean evaporation is a certain event. Then let’s take a look at the current ecological situation of the earth. Due to the rapid development of human industry, a large amount of carbon dioxide has been produced, resulting in the increasing greenhouse effect.
Now the temperature of the earth has been rising. I believe you can feel that the temperature has been rising in the past five years. Today’s temperature should be even higher than last year’s. I believe that in more than one month, my friends will be able to feel the difficult high temperature season. If the rising trend of global temperature can not be controlled, when the temperature of the ocean surface rises above 45 ℃, the ocean will initially evaporate, a large amount of water vapor will rise to the atmosphere, the rainfall will increase significantly, and the duration will continue to extend.
It can be seen that the future of the earth is not as optimistic as we thought. The long rain that happened more than 200 million years ago is still possible in the future. If we want it not to happen, we can only strengthen environmental protection, so that the global temperature will not rise. But can we do such a thing?
