प्रश्न
Magnetosphere of the earth is a result of rotation. Explain.
लघु उत्तर
उत्तर
- The average temperature of the outer core of the earth is around 5000° C. The average temperature of the inner core of the earth is around 6000° C. This difference between the temperature results in formation of vertical currents.
- The rotation of the earth gives eddy (circular) motion to these currents.
- Electric currents develop in these spiral eddies of liquid iron leading to generation of the magnetic field of the earth. This magnetic field is called magnetosphere. In this way, the magnetosphere is formed due to the rotation of the earth.
