Question

One and a half million years ago the indicator on a compass needle would have pointed to the North.

True
False

Answer 1

False

Step-by-step explanation:

The statement is false. The indicator on a compass needle would not have pointed to the North as it did today one and a half million years ago. The Earth's magnetic field is not constant and changes over time. Magnetic pole reversals occur when the magnetic North and south poles switch places. The Brunhes-Matuyama reversal, the most recent significant reversal, occurred approximately 800,000 years ago. As a result, one and a half million years ago, the compass needle would have pointed somewhere other than North.
