Question

which hypothesis was confirmed using paleomagnetic evidence?
hot spots
transform boundaries
seafloor spreading
subduction

Explanation:

Paleomagnetic evidence (study of Earth's ancient magnetic fields preserved in rocks) was crucial in confirming the seafloor spreading hypothesis. As new oceanic crust forms at mid - ocean ridges, it records the Earth's magnetic field at that time. The alternating magnetic stripes on the seafloor, discovered through paleomagnetic studies, matched the pattern predicted by seafloor spreading (where new crust is added and moves away from the ridge). Hot spots are related to stationary mantle plumes, transform boundaries are about lateral plate movement, and subduction is about one plate going under another; paleomagnetic evidence is not the key confirmation for these as it was for seafloor spreading.

Answer:

C. seafloor spreading
