Earth's core studies

Earth's core studies focus on understanding the planet's innermost layers, which consist of a solid inner core and a liquid outer core. These layers play a crucial role in generating Earth's magnetic field through movements of molten iron and nickel. This process, known as the geodynamo, creates geomagnetism, which protects the planet from solar radiation and influences navigation systems. Scientists use seismic waves, magnetic measurements, and computer simulations to examine the core's properties and behaviors, helping us understand not only Earth's geology but also its magnetic environment and its effects on life and technology above the surface.
