Massive Asteroids, Comets Once Bombarded Earth That Altered Oxygen Levels in the Atmosphere

Oct 26, 2021

Researchers led by Harvard University studied remnants of ancient asteroids and found that massive space rocks have bombarded Earth before, which delayed the accumulation of oxygen on the planet.

Earth's Evolution: Photosynthesis Might Have Started 400 Million Years Before the Great Oxidation

Oct 04, 2021

When did photosynthesis start? The new gene-analyzing technique provided evidence that it might have begun even before the Great Oxidation Event, suggesting a new timeline of Earth's evolutionary history.

Volcanoes Provide Earth's Atmosphere First Oxygen 100 Million Years Earlier Than Great Oxidation Event

Aug 30, 2021

A new study suggests that volcanoes are responsible for the first existence of oxygen on Earth 100 million years earlier than the Great Oxidation Event.

The Great Oxidation Event Explained: Scientists Developed a Model to Describe How the Tectonic Plates Affected the History of the Atmosphere

Dec 12, 2019

Scientists behind the study used detail modeling and discovered that an increase in tectonic activity produced new volcanoes prior to the Great Oxidation Event which pumped big amounts of carbon dioxide in the air which led to the warming of the climate, increased rainfall, and leading to more minerals washed into the ocean.
