COMMON KNOWLEDGE
Legacy classification; evidence review pending
Recorded sources
no sources on either side

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that ocean floor magnetic anomalies enable the reconstruction of ancient continental positions?

The use of marine magnetic anomalies (stripes of normal and reversed polarity locked into oceanic crust) to determine seafloor spreading rates and reconstruct past plate positions and continental drift is a foundational, textbook concept in geophysics and plate tectonics, requiring no citation.

The analysis

The claim states that ocean floor magnetic anomalies enable the reconstruction of ancient continental positions. This is a classic, foundational principle of marine geophysics and plate tectonics (Vine-Matthews-Morley hypothesis). It is common knowledge within Earth sciences, taught in introductory geology courses worldwide, and does not depend on contestable or cutting-edge research findings for its basic validity. Therefore, per the instructions for common knowledge, no citations are needed and index lists are left empty.
