Study Suggests Earth's Slowing Rotation Led to More Oxygen in Atmosphere

Summary by Ground News

Earth's rotation has been gradually slowing down, and its days gotten progressively longer as a result. The blue-green algae that emerged and proliferated about 2.4 billion years ago would have been able to produce more oxygen as a metabolic by-product. Evidence suggests that we're gaining 1.8 milliseconds a century.

Study Suggests Earth's Slowing Rotation Led to More Oxygen in Atmosphere

A new study suggests Earth’s supply of oxygen developed thanks to the planet’s gradually slowing rotation creating longer days that allowed a certain form of algae to admit more oxygen as a byproduct of its metabolic process.The study, published Monday in the scientific journal Nature Geoscience, suggests that about 2.4 billion years ago there was so little oxygen in Earth's atmosphere, it could barely be measured, so no animal or plant life as …

A Slowdown in Earth’s Rotation Could Have Affected the Oxygen Content of the Atmosphere

A long day for microbes, and the rise of oxygen on Earth. Virtually all oxygen on Earth was and is produced by photosynthesis, which was invented by tiny organisms, the cyanobacteria, when our planet was still a rather uninhabitable place. Cyanobacteria evolved more than 2.4 billion years ago, but

Possible link between Earth’s rotation rate and oxygenation - Nature Geoscience

Rotational deceleration has increased daylength on Earth, potentially linking the increased burial of organic carbon by cyanobacterial mats and planetary oxygenation, according to experiments and modelling of Precambrian benthic ecosystems.

The rise of oxygen on early Earth linked to changing planetary rotation rate

Ann Arbor MI (SPX) Aug 03, 2021 The rise of oxygen levels early in Earth's history paved the way for the spectacular diversity of animal life. But for decades, scientists have struggled to explain the factors that controlled this gradual and stepwise process, which unfolded over nearly 2 billion years. Now an international research team is proposing that increasing day length on the early Earth-the spinning of the young
