Electromagnetically driven westward drift and inner-core superrotation in Earth’s core

“Seismic probing of the earth’s deep interior has shown that the inner core, the solid core of our planet, rotates slightly faster (i.e., eastward) than the rest of the earth.”

World’s Deepest Mines Highlight Risks of New Gold Rush

“As gold prices reach near-record highs, South Africa’s mining companies are keeping up by drilling to record depths.”

How the Mariana Trench Became Earth’s Deepest Point

“The Mariana Trench isn’t really the deep, narrow furrow that the word “trench” implies. Rather, the abyss marks the location of a subduction zone.”

Will the magnetic field of the Earth reverse its direction in the future? Will this cause problems?

“The magnetic field of the Earth has actually switched its direction many many times during Earth’s history. Although this is not completely understood, the leading theory of how it works is that Earth’s magnetic field is caused by the motion of the liquid outer core. The churning of the liquid in the outer core acts as a giant electromagnet, moving electrical charges around, in what is known as the ‘geomagnetic dynamo.'”

What If Earth’s Magnetic Poles Flip?

“The end of the world as we know it could come in any number of ways, depending on who you ask. Some people believe global cataclysm will occur when Earth’s magnetic poles reverse. When north goes south, they say, the continents will lurch in one direction or the other, triggering massive earthquakes, rapid climate change and species extinctions.”

New insights solve 300-year-old problem: The dynamics of the Earth’s core

“Scientists at the University of Leeds have solved a 300-year-old riddle about which direction the centre of the earth spins.”
