Geophysics explores Earth's physical processes, from its core to its atmosphere. Discover how we study earthquakes, volcanoes, and the planet's magnetic field.
Studies suggest the solid inner core spins slightly faster than Earth's mantle and crust, gaining about 0.08 to 0.1 degrees of longitude annually. This differential rotation is influenced by the magnetic field generated in the liquid outer core.
The magnetic north pole is currently moving at speeds up to 55 kilometers (34 miles) per year, causing issues for navigation systems and requiring more frequent updates to global magnetic models. This drift is driven by the motion of molten iron in Earth's outer core.
The collision of the Indian and Eurasian tectonic plates continues to push the Himalayas upwards. This ongoing geological activity means the world's highest peak is constantly, albeit slowly, increasing in elevation, a testament to Earth's dynamic forces.
