    Ancient ocean floor discovered at the boundary of the Earth’s core and mantle

    (ORDO NEWS) — Scientists at the University of Alabama have discovered a thick, thin layer that may be the ancient ocean floor between Earth‘s core and mantle. A study uses global seismic imaging to uncover a layer of ancient ocean floor that may span the boundary between the core and the mantle. This ultra-low velocity zone (ELZ) is deep underground and is denser than the rest of the deep mantle,…

    Plates of the ancient lithosphere fold “mountains” above the earth’s core

    (ORDO NEWS) — Seismic observations have shown that at a depth of thousands of kilometers, on the border of the core and mantle, there are massive and dense “mountains” up to several tens of kilometers high. Geologists consider them to be the remains of ancient oceanic plates. The Earth‘s core lies at a depth of about 3,000 kilometers, hundreds of times lower than the deepest wells we can drill. Therefore,…

    There may be another core inside the Earth’s core, scientists say

    (ORDO NEWS) — In fact, the Earth may have two solid inner cores: the inner core and the shell, which does not yet have a name. It seems that the internal structure of the Earth simply has no end. A new study shows that a component known as the “inner core” is made up of an innermost core and a middle core. Although both are likely composed of solid iron…

    An unusual mini-core was discovered in the center of the Earth’s core

    (ORDO NEWS) — The composition of the innermost part of the planet, as it turned out, is seriously different from the core as a whole. It was not previously possible to detect it due to the difficulties of studying this part of the planet. Until now, it was believed that the solid, inner part of the Earth has a radius of just over 1200 kilometers (diameter – about 2500 kilometers).…

    Scientists warn about the risk of an explosion of the Earth’s core

    (ORDO NEWS) — Scientists warn the public about the risk of an explosion in the Earth‘s core. As follows from the material, the cause of such catastrophic consequences could be global warming. According to a recent study, not only the Earth’s biosphere is currently under threat, but also the Earth’s inner core , which has a rounded shape and a diameter of about 2,000 kilometers. Its dimensions, experts say, are…

    Is the Earth’s core rusting?

    (ORDO NEWS) — If subduction transports hydrogenous minerals deep into the Earth‘s mantle, they can “rust” in the iron outer core, forming huge reserves of oxygen that can later be returned to the atmosphere. Iron on the surface of the Earth – whether simple nails or powerful beams – when exposed to moist air or oxygenated water, gradually enters into a chemical reaction known as oxidation. The reddish-brown product of…

    Geophysicists have found that carbon leakage from the Earth’s core leads to the formation of diamonds

    (ORDO NEWS) — Scientists from the University of Arizona have found that diamonds are forming at the boundary between the core and the mantle of the Earth, and a process similar to the formation of rust is going on. The study is published in Geophysical Research Letters. The Earth’s core contains approximately 90% of the planet’s carbon. It is surrounded by a mantle, and it was previously thought that there…

    Rusting Earth’s core may release diamonds at the edge of the mantle

    (ORDO NEWS) — The iron-nickel alloy of the earth’s core contains a large amount of dissolved carbon. Scientists have identified a process that can lead to the release of this carbon into the mantle and the formation of diamonds from it. The largest reservoir of carbon on Earth is not the biosphere at all, but the earth’s core . It consists of an iron-nickel melt, in which light elements are…

    Why doesn’t the Earth’s core cool down

    (ORDO NEWS) — If you look at the terrestrial planets – Mercury , Venus , Earth and Mars – then you involuntarily think about why confirmed volcanic and tectonic activity has survived only on Earth. Why did the interiors of three other planets cool down (it is worth noting that the core of Mars probably remains partially heated)? Why did the giant volcanoes of Mars “silence”? Perhaps the heating of…

    Giant mysterious magnetic waves emanate from the Earth’s core every seven years

    (ORDO NEWS) — It’s not very quiet inside the Earth. Deep below the surface, the planet is literally seething with activity, from plate tectonics to convection currents circulating in hot magma fluids. Now scientists studying data from Earth’s satellites have discovered something inside the Earth that we’ve never seen before: a new type of magnetic wave that travels across the surface of our planet’s core every seven years. This discovery…

Deep below the surface, the planet is literally thundering with activity, from plate tectonics to convection currents that circulate through hot magma fluids. Now scientists studying Earth satellite data have identified something inside the Earth that we have never seen before: a new type of magnetic wave that sweeps around the surface of our planet’s core every seven years.

    Primordial helium, formed billions of years ago, seems to be leaking out of the Earth’s core

    (ORDO NEWS) — Ancient, primordial helium from the Big Bang is leaking out of the Earth‘s core, scientists say in a new study. There is no reason to be alarmed. The earth does not deflate like a sad balloon. But this means that the Earth formed inside the solar nebula – the molecular cloud from which the Sun was born, and this detail of the birth of our planet remained…

    Scientists have discovered strange signals coming from the core of the Earth

    (ORDO NEWS) — The Earth‘s magnetic field is the result of charged particles being trapped in a turbulent dance of convective currents deep below the surface. A team led by Nicolas Gillet at the University of Grenoble-Alpes in France found that the planet’s magnetic field fluctuates like clockwork every seven years, moving westward at 900 miles per hour around the equator, suggesting that there is still much to be learned…

    (ORDO NEWS) — Scientists have discovered helium-3, a rare primordial gas escaping from the Earth‘s core. This gas is mainly formed in the nebula when the star comes to life. The earth has evolved over billions of years, yet the mystery of its formation remains shrouded. A leak at the planet’s core has now given hints of the formation of our world, which begins with the Big Bang, and the…
