Responses
The fossil is younger than the layer of rock it was formed in.

The fossil is younger than the layer of rock right above it.
The fossil is younger than the layer of rock right above it.
The fossil is older than the layer of rock right below it.
The fossil is older than the layer of rock right below it.
The fossil is older than the layer of rock it was formed in.
The correct answer is: The fossil is older than the layer of rock it was formed in.
If a supercontinent did not exist, the presence of the same life form species fossils on continents now separated by oceans could be explained by the phenomenon of animal dispersal, where organisms would have migrated across land bridges or through other means of transportation to reach these disparate continents before they drifted apart.
Use this sentence: A fault cuts across several layers of rock.
Which conclusion can be made?
(1 point)
Responses
The fault is younger than the layers of rock based on the law of crosscutting.
