Answer 1

1. The evidence that would confirm that a given rock layer is newer than the layers around it is: It cuts through all the other layers. This indicates that the layer in question must have formed after the layers it intersects.

2. Mohorovičić's observation was: Seismic waves travelled at varying speeds. This observation led to the conclusion that Earth's internal structure must have different materials and states, causing seismic waves to travel at different speeds through them.
