Question

during which type of solar weather would one predict power grid operations on earth could degrade? (1 point)

○ solar flares

○ coronal mass ejections (cmes)

○ solar wind

○ solar energetic particles

Explanation:

Coronal mass ejections (CMEs) are large bursts of magnetized plasma from the Sun. When they collide with Earth's magnetosphere, they can trigger intense geomagnetic storms. These storms induce strong electric currents in power grids, which can damage transformers and disrupt or degrade grid operations. Solar flares primarily affect radio communications, solar wind is a steady, low-density stream that rarely causes severe grid issues, and solar energetic particles mainly impact satellite electronics and astronaut safety, not power grids directly.

Answer:

coronal mass ejections (CMEs)
