E Prime Layer

A study by an international team of researchers revealed the formation of a new enigmatic layer – E prime layer at the outermost part of Earth's core.

• Recent research has unveiled a surprising exchange between Earth's core and mantle.
• Water carried by tectonic plates over billions of years reacts with the core, forming silica at the core-mantle boundary.
• This chemical reaction alters the core's structure, creating a hydrogen-rich, silicon-depleted layer.
• Silica crystals ascend into the mantle, impacting its composition.
• These findings deepen our understanding of Earth's internal processes, revealing a complex global water cycle and interconnected geochemical processes between surface water ....
