The findings, published in the academic journal Science on Friday, reshape human understanding of how water is stored and ...

When the early Earth’s magma ocean crystallized 4.4 billion years ago, the deep mantle trapped an ocean’s worth of water, ...

Far below the oceans and continents we know, Earth’s deep mantle appears to have stored far more water in its early history ...

Today, oceans cover about 70% of Earth’s surface. This stark contrast has long driven scientific interest in how water ...

New evidence indicates that the deepest realm of the mantle flowed with up to 100 times more water than previously believed.

According to the researchers, the deeply buried water is not a static stockpile. It acts like a "lubricant" for the colossal geological engine of Earth, lowering the melting point and viscosity of ...

Researchers from the Guangzhou Institute of Geochemistry under the Chinese Academy of Sciences have experimentally demonstrated that the planet's deep mantle could have acted as a massive reservoir ...

Some 4.6 billion years ago, Earth was nothing like the gentle blue planet we know today. Frequent and violent celestial impacts churned its surface and interior into a seething ocean of magma—an ...

Far below the familiar blue of the surface oceans, geophysicists are piecing together evidence for a vast, hidden reservoir ...

A new study highlights the key role the Southern Ocean plays in the Earth’s climate system. Around 12,000 years ago, the last ...
