A new study has suggested that the presence of diamonds deep beneath the Earth could explain why earthquakes occur at such depths, claiming that super-hot rocks release water that weakens surrounding rocks and triggers quakes. The study follows earlier hypotheses on superdeep earthquakes and explores whether water stored hundreds of kilometers below the Earth’s surface may be responsible for the... 

Despite decades of research, scientists remain divided about many of the processes taking place beneath our planet’s surface, including details about the churning of molten metals in the Earth’s core which creates the magnetic field that protects the planet from deadly solar radiation. Two massive formations of incredibly hot molten rock the size of continents are lurking underneath Earth’s... 

Scientists have virtually denied the existing hypothesis about the formation of the Earth’s core. It was believed that the metal core of all celestial bodies is formed under the same scheme. However, recent experiments demonstrated that there are other ways to form the core. It turns out that this process should be seen as unique to each celestial body. Scientists base the hypotheses of formation...
