dentify the true statement. a. The series of rock stripes perpendicular to and bilaterally symmetric across the mid-ocean ridge records the sequence of the Earth's magnetic reversals over time. b. All polarity chrons are the same length of time; they differ only in the magnetic strengths they represent. c. The width of each rock stripe is a measure of how long the polar direction took to change. d. Positive magnetic anomalies occur where seafloor basalt has the same polarity as Earth's present-day magnetic field.

All the statements except statement B are true.

Explanation:

The magnetic field reversals that have happened on earth from time to time are evident from the geological features found near the mid-oceanic ridge. The rock stripes stopped developing in a single direction after the polar direction of the region changed. Hence, the patterns that are seen in the rock stripes can be deemed as proof of magnetic field reversals from time to time.
