Earth's magnetic field will reverse orientations in approximately

Question

Quizplus · Accepted Answer

Earth's magnetic field reversals are unpredictable, but geological records show they have happened numerous times throughout Earth's history. The last reversal occurred roughly 780,000 years ago, and while the timing of these reversals is irregular, suggesting one might occur every few thousand to millions of years, there is no precise prediction that it will happen in exactly 2,000 years. However, "B" is the closest to the unpredictable nature of these events, as it acknowledges the possibility of a reversal in a relatively short geological timeframe without specifying an exact schedule.
