Answer

Brief Explanations:

The patterns of magnetic striping on the ocean floor provided evidence for the movement of tectonic plates. As new ocean - crust is formed at mid - ocean ridges, magnetic minerals align with the Earth's magnetic field. Reversals in the Earth's magnetic field create alternating magnetic stripes, indicating sea - floor spreading which is a key concept in plate tectonic theory. Ocean salinity, temperature variations in currents, and sediment thickness are not directly related to the development of plate tectonic theory from ocean floor studies.

Answer:

A. Patterns of magnetic striping on the ocean floor
