Earth’s Inner Core Is Slowing Down | Seismic Discovery & Magnetic Field Impact Seismic studies reveal that Earth’s solid inner core does not rotate at a constant rate. Since around 2010, it has slowed slightly, lagging behind the mantle and crust. Scientists detected these changes by analyzing tiny differences in seismic wave arrival times through the iron-rich core. This slowdown affects the geodynamo, influencing Earth’s magnetic field and the flow of liquid iron in the outer core. Understandi

🧭 Earth’s magnetic North Pole is on the move — again. Driven by the flow of molten iron in Earth’s outer core, the magnetic North Pole has been drifting away from Canada toward Siberia — and it’s not just a slow wander anymore. At its peak, the pole was shifting up to 50 km per year. This isn’t just a science fact — it affects everything from airplanes to smartphones. That’s why scientists constantly update magnetic field models to keep navigation systems accurate. Earth’s magnetic field is ali

Why Earth's Outer Core is liquid and Inner Core is Solid? The liquid iron and nickel in the outer core move around soild inner core like a dynamo, creating Earth's magnetic field. This geomagnetic force protects us from harmful solar radiation and guides navigation. #Geoscience #EarthScience #InstaScience #upsc #reelsinstagram | Rohan Tyagi
