7. The Interior of the Earth. —Whenever borings have been made into the interior of the earth it has been found, after a depth had been reached where there was no effect from the heat of the sun, that the temperature rose as the boring increased. From this gradual increase of temperat...

The collapse of the Earth’s magnetic field―which guards the planet and guides many of its creatures―appears to have started seriously about 150 years ago, the New York Times reported last week. The field’s strength has decreased by 10 or 15 per cent so far and this has increased the...

or simply structure of Earth refers toconcentric spherical layerssubdividing the Solid earth, i.e., excludingEarth's atmosphereandhydrosphere. It consists of anouter silicate solid crust, a highlyviscous asthenosphereandsolid mantle,a liquid outer corewhose flow generates theEarth's magnetic field, an...
Researchers believe Psyche to be an exposed iron core of a young planet. Studying planetary cores is nearly impossible on actual planets because they are so deep underground, so Psyche could present a unique opportunity.“The core is always crucial. For the Earth, it creates magnetic field( ...
Deep below the surface of the Earth is the liquid outer core of the planet. This core is composed mostly nickel and iron and rotates independently of the rest of the planet. This spinning ball of iron creates the Earth's magnetic field....
Earth's protective magnetic field is weakening in a region across the South Atlantic. What's going on, and should we be worried?
