A meteor 4 times the size of Everest hits the Earth, this is the effect

Jakarta, CNN Indonesia —

A recent study revealed that the Earth was hit meteor a giant 4 times the size of Mount Everest about 3.26 billion years ago.

The study, published in the Proceedings of the National Academy of Sciences, shows how the “S2” meteorite impact more than 3 billion years ago relates to geological evidence found in the Barberton Greenstone Belt in South Africa today.

Nadja Drabon, an early earth paleontologist and assistant professor in the Department of Earth and Planetary Sciences at Harvard University, and her team collected and processed rock samples separated by several centimeters and analyzed the sedimentology , the geochemistry and carbon isotope composition of their remains.

From this study, Drabon’s team provided a fascinating picture of what happened the day a meteorite the size of Mount Everest hit Earth.

“Imagine yourself standing off the coast of Cape Cod, at the edge of shallow water. It’s a low-energy environment, with no strong currents. Then all of a sudden, there’s a huge tsunami that sweeps up and tearing up the seabed,” said Drabon. by Science Daily , Monday (21/10).

The S2 meteorite is estimated to be 200 times larger than the meteorite that killed the dinosaurs. This meteor triggered a tsunami that stirred the ocean and washed debris from land to coastal areas.

This study states that the heat generated by the impact caused the top layer of the ocean to boil, as well as heating the atmosphere. Then, a thick cloud of dust surrounded everything, killing any ongoing photosynthesis activity.

However, bacteria have a persistent nature. According to the research team’s study, bacterial life quickly recovered after the stroke occurred.

Therefore, there was a significant increase in the number of unicellular organisms that consume phosphorus and iron elements. Iron​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​1,​​th​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​1,​​​​​​​​ of ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​, is the owner, ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ of iron with iron with an increase in weathering and erosion on land, as well as increased weathering and erosion on land, and phosphorus delivered to Earth, appeared as a result of the tsunami.

Drabon’s study shows that bacteria that metabolize iron grow rapidly after the tsunami.

The shift towards iron-loving bacteria, though brief, is a key piece of the puzzle that describes early life on Earth.

According to Drabon’s study, the impact of the S2 meteor could have a positive effect.

“We think of impact events as catastrophic for life. However, this research shows that these impacts had life benefits, especially in the early days…they allowed life to develop ,” said Drabon.

In addition, the results of this study were obtained from the hard work of geologists such as Drabon and his students. They climb into mountain crevices that contain sedimentary evidence from early rocks that entered the ground and were preserved over time in the Earth’s crust.

Chemical signatures hidden in thin layers of rock help Drabon and his students gather evidence of tsunamis and other catastrophic events.

In the Barberton Greenstone Belt in South Africa, where Drabon is currently focusing much of his research, there is evidence of at least eight meteor impact events including S2.

He and his team plan to explore the area further to study the Earth and its history as it relates to meteorites.
