We face 'life source from hell' every day without knowing it?

Research just published in Nature Geoscience shows the incredible way Earth managed to become a planet rich in life.

Where oxygen - the source of life for all species on earth - comes from and how it became so abundant is still an interesting question that many scientists have tried to find the answer to.

From seeds in space, from biological processes of primitive microorganisms. many studies have shown, but something is still not enough. Earth scientists from Laurentian University (Canada) and Michigan University (USA) have pointed out another unbelievable source: From "hell" underground .

Was the source of life for all species on Earth liberated from the hot "hell" deep below, through the violent plate tectonics of the early days? - (Illustration from the Internet).

Geological data show that during the Neoarchean —the final period of the Archean eon—about 2.8 to 2.5 billion years ago, abundant oxygen in the Earth's atmosphere was virtually absent.

New data show that at the very end of that period, oxygen was introduced in unusual abundance, coinciding with a period of intense plate tectonics 2.7 billion years ago.

Plate tectonics can be explained simply as follows: the Earth's crust is not continuous but consists of many large and small pieces, estimated to have about 15-20 pieces today, each piece carrying on its back a part of an ocean or continent. These pieces are constantly moving, causing the continents and oceans on Earth to merge many times to form supercontinents, superoceans and then separate again.

When plate tectonics occurs, some of what is above ground is swallowed up and recycled, while much of the rock and material that is hidden deep down also has a chance to rise to the surface.

According to the research team's article in The Conversation, they collected the remains of that 2.7 billion-year-old plate tectonics - the so-called "Superior Province ", a continental plate that has fortunately remained intact since the late Archean, now spanning several localities in the US and Canada.

By measuring the ratios and concentrations of certain elements trapped in the ancient rocks, they determined that the magma in this ancient continent was highly oxidized. The period of oxidized magma also coincided with the period of major gold mineralization in outback Western Australia, which is evidenced by world-class ore deposits today.

So the subduction process during that ancient plate tectonics—swallowing large chunks of ocean into the Earth and releasing others to the surface—also released dissolved oxygen from somewhere deep and mysterious.

This allowed scientists to conclude that there is a high probability that there is oxygen present inside rocky planets.

This also explains the "breathlessness" of other rocky planets in the Solar System, despite being born in the habitable zone. Because Earth is the only planet confirmed to have plate tectonics. Perhaps a violent disturbance that releases the potential source of life is something that fellow planets like Mars and Venus lack.
