Geology is an amazing subject. Especially now when so much is happening around the world in terms of volcanic eruptions and seismic activities. Let’s review how the interior of the Earth is structured. We’ll take a journey into the depths of the Earth, down through the crust and mantle, nearly to the core. We’ll use ...
Pierfranco Demontis said in 1988: “Ice becomes a fast-ion conductor at high pressure and high temperatures,” but his prediction was only hypothetical until recently. After 30 years of study, superionic phases of water ice were verified experimentally in 2018. Superionicity may eventually explain the strong magnetic field in giant planetary interiors and Earth’s deep mantle. ...
The huge magnetic field that surrounds the Earth, protecting it from radiation and charged particles from space — which many animals even use for orientation purposes — is changing all the time, which is why geoscientists constantly keep it under surveillance. The old well-known sources of the Earth’s magnetic field are the Earth’s core — ...
