Surface Water Penetrates Deep into Earth, New Research Suggests
A few decades ago, seismologists identified a thin layer with a lower velocity in Earth’s metallic liquid core. The origin of this layer, known as the E’ layer, has been a mystery. Now, geoscientists have revealed that water from the Earth’s surface can penetrate deep into the planet, altering the composition of the outermost region of the core and creating the E’ layer.
