Earths Structure And Layers Questions
The geodynamo theory is a scientific explanation for Earth's magnetic field. It proposes that the magnetic field is generated by the movement of molten iron in the outer core of the Earth. As the Earth rotates, the liquid iron in the outer core undergoes convection, creating electric currents. These electric currents, combined with the Earth's rotation, generate a magnetic field through a process called the dynamo effect. This magnetic field extends from the Earth's core to the outer space, protecting the planet from harmful solar radiation and guiding compass needles.
