Question

8/10
which evidence supports the theory of seafloor spreading?
presence of marine fossils on mountaintops
age of rocks varies with distance from mid-ocean ridges
continental shapes fitting like puzzle pieces
similarity of moon rocks to earth rocks

Explanation:

Seafloor spreading theory states new ocean crust forms at mid-ocean ridges and moves outward. Rocks farthest from ridges are oldest, matching this process. The other options support continental drift or unrelated planetary comparisons, not seafloor spreading specifically.

Answer:

Age of rocks varies with distance from mid-ocean ridges
