← ScienceWhich risk increases when geomagnetic fields strongly fluctuate?
A)Induced currents in long pipelines✓
B)Reduced GPS signal propagation time
C)Increased solar panel energy conversion
D)Improved shortwave radio communication range
💡 Explanation
Geomagnetic storms induce telluric currents; therefore, long pipelines are particularly vulnerable to corrosion caused by stray electrical currents, because the pipelines serve as unintentional grounding paths, rather than improved communications performance.
