Answer:
GPS positioning systems will stop functioning.
Step-by-step explanation:
Solar storms are strong electromagnetic waves. These are produced on the surface of the sun, and these massive waves sometimes hit the earth's atmosphere. These waves disrupt the radio signal waves present in the earth's atmosphere and block the satellite communication to the earth. As a result, the GPS will not work. Due to its waves, the power grids stops to work. It also disturbs electricity and telephone communication. These solar storms are molten lava which produces on the sun by nuclear fusion.
