Fossils of land plants were found in an upper sedimentary rock layer, while fossils of aquatic animals were found in a lower layer beneath it. What does this suggest about the environmental changes that occurred in this region over time?
The region was always covered by water with no significant changes.
The region was a forested land before it became an ocean.
The region was an ocean first and later transformed into a land with vegetation.
The region was a desert before becoming a forest.

The diagram shows alternating bands of normal and reversed magnetic polarity on both sides of the Mid-Atlantic Ridge. What does the symmetry of these magnetic bands suggest about the process occurring at the ridge?
It suggests that oceanic crust is older near the ridge.
It indicates that new oceanic crust is continuously formed at the ridge and moves away on both sides.
It shows that magnetic reversals only happen at the Mid-Atlantic Ridge.
It proves that the Mid-Atlantic Ridge is the only place where seafloor spreading occurs.
Based on the information shown in the map, which statement is most supported?
