Thunder and rain are very common natural phenomena. During the drought, people hope for rain to save crops. In hot summer, a rain can bring a little coolness to people, and our common rain is a transparent and tasteless liquid. Now with the rapid development of science and technology, scientists have understood the causes and formation process of rain, and there is artificial rainfall. If there is red rain in this world, then everyone may think that this brain hole is wide open: it is stained with rain.
Looking through ancient books, we can find that rain is not all transparent, and there are colored rain, which people think is colored. Blood rain? . The earliest record of this colorful rain is the Iliad written by the poet Homer. A long time ago, Germany, Italy and California all had blood rain, and some of them were mixed with fat meat, which smelled bad. The color of the rain is as bright as blood, which is shocking.
For what? Blood rain? Scientists are interested in the source, but they haven't completely solved it. Scientists say that rain is mixed with red dust; Or animals such as birds are injured and bleed in the storm, making the rain turn red; Or some chemical elements contained in rainwater are related to chemical reactions under certain circumstances; Or some microorganisms mix into the rain to make an adaptive response to the environment, thus producing this red color. ?
