Question

which of the following is not evidence for the theory of seafloor spreading?
o the presence of magnetic rocks at and near the mid - ocean ridge
o core samples from around the mid - ocean ridge
o the presence of fossils at the mid - ocean ridge
o the presence of molten material at the mid - ocean ridge

Explanation:

Seafloor - spreading evidence includes magnetic rocks (due to Earth's magnetic field reversals), core - samples showing age differences, and molten material at mid - ocean ridges. Fossils at mid - ocean ridges are not typical evidence as the mid - ocean ridge environment is not conducive to long - term fossil preservation due to high heat and tectonic activity.

Answer:

the presence of fossils at the mid - ocean ridge
