← ScienceWhich outcome occurs when geomagnetic disturbance amplifies telluric currents?
A)Pipeline corrosion rate increases✓
B)Transformer core saturation decreases
C)Satellite navigation accuracy improves
D)Radio communication signal strength rises
💡 Explanation
An increased geomagnetic disturbance amplifies telluric currents in pipelines, and because galvanic corrosion rate depends directly on this ground current, it will increase. Therefore, corrosion increases, rather than navigation improving or transformers improving under steady rather than elevated current signals.
