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.
