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

🧭 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
