Earth's magnetosphere is generated by

Question

Quizplus · Accepted Answer

Earth's magnetosphere is generated by dynamo-like motions in Earth's interior, specifically in the liquid outer core. These motions, driven by the heat flow from the core to the mantle, generate electrical currents that produce the magnetic field surrounding the planet. The magnetosphere helps protect Earth from harmful solar radiation and cosmic rays. The other options (A, B, and D) are not correct as they do not involve dynamo-like motions in Earth's interior.
