Evidence Supporting Continental Drift

The video discusses Alfred Wegener's theory of continental drift, initially rejected due to lack of explanation for the movement of continents. Advances in technology in the mid-20th century allowed scientists to explore the ocean floor, leading to the discovery of mid-ocean ridges and volcanic activity. The theory of seafloor spreading emerged, suggesting that continents ride on moving oceanic plates. Evidence supporting this theory includes young ocean floor rocks, magnetic orientation of basaltic rocks, and parallel magnetic stripes on either side of mid-ocean ridges.

How do rock samples from the ocean floor support the theory of seafloor spreading?

What evidence related to magnetic orientation supports the concept of seafloor spreading?
