The stronger the magnetic field around the Earth, the higher the oxygen level. It is an astonishing discovery of a new study looking at the planet’s history for over 5 billion years.
Researchers can track the rise and fall of oxygen levels by studying the charcoal left behind from ancient wildfires. The more oxygen you have, the greater the fire. Additionally, changes in the geomagnetic field can be measured by studying rocks formed by ancient volcanic eruptions. Magnetic crystals found in cooling lava are aligned with the geomagnetic field and provide indications of its strength.
The new study combines these data to reveal a strong link between oxygen levels and the strength of the geomagnetic field. Over the past 540 million years, magnetic field strength has increased, oxygen levels have increased, and planets have put more life on them. Survey results It was published in Advances in science.
“We don’t have a really good explanation about that,” said Benjamin Mills, a co-author at the University of Leeds. I said Naturealthough he provided some ideas.
Their movements have unleashed the essentials of hundreds of millions of years as structural plates have changed. Nutrientszinc and phosphorus enter the sea and burn giant algae flowers. These flowers produced a large amount of oxygen. Scientists may suggest that the same current that drives the movement of the tectonic plate can also affect the Earth’s iron core, the source of its magnetic field.
