- How do we know how old a fossil is? A) We compare it to current species and see how much has changed B) We see how much soil is on top of it C) We use radiometric datingarrow_forwardOne type of fish fossil is found only in a rock layer near the bottom of a canyon, while a different kind of fish fossil is found only in a rock layer 4,000 feet higher, near the top of the canyon. Which statement would a scientist most likely offer to explain this situation? A.) The fish in the lower layer lived in the deep sea. While the other fish lived in shallow water. B.) The fish in the upper layer lived a healthier life than the other fish. C.) The rock in the lower layer is denser than the rock in the upper layer D.) The rock in the upper layer must have formed in freshwater E.) The fish in the upper layer lived more recently than the other fish. The Geologic Time Scale is a systematic chronological dating process that relates geological strata to time. This methodology is commonly used be geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events that once occurred in history.

- How does finding the same fossils of a land animal on two different continents support the hypothesis of continental drift? A) The land animal fossil is now found in colder parts of the world which means the continents had drifted since the fossils were made. B) The land animal fossil could only have ended up fossilized on both continents if they were once together C) The land animal fossil was unable to swim across oceans so the fact that its fossils were found on distant continents suggested those continents had once been fused together as later moved apart.
