The Swiss planet group decided to enter the study about the appearance of the oceans. They have studied the composition of meteorites found on earth, especially the manganese and chromium ratio in it. These factors belong to volatile substances, the content varies depending on the distance from the sun is the body in the sky.
It turns out in meteorites, the average manganese and chromium ratio is 0.8.
At the same time, this index is about half of the earth's rocks. The greater the chromium ratio in the ratio, the main substance is the main substance.
Therefore, the soil was not as humid as now and the water appeared on the planet due to external influence.
Scientists have simulated the process of forming planets in the Solar System and came to the conclusion that if the water was collected on Earth gradually, in the process of increasing the mass of the planet, its quantity would be much less realistic. An article on research has been published in Science Advances magazine.
Comet, clear, unable to cause the formation of the Ocean world – most of these bodies come in the earth from the trajectory of the Neptune, where many people eat, however, in the country present on our planet, Deres is very small.
The scientists have hypothesized the earth's clash with another heavenly body, because the ocean was formed. According to scientists, this may occur about 4.5 billion years ago. However, such a scenario can only occur if there are many manganese in the body of the body crashing to the ground, and its mass is about 10 times lower than the mass of the Earth.
Earlier, it was known that scientists investigated an example of ancient atmosphere on the planet. It was found in a rock for more than 800 million years. The analysis of this substance can get new information about the Early Early atmosphere. Scientists studied stone salt samples obtained in Australia in 2016, in particular, small air bubbles inside them. The results show that oxygen in the ancient atmosphere of the earth is about twice than now. However, this amount is enough to survive animals.
