Yes you can, for which one both?
The amount of time it takes Earth to rotate on once on its axis would be 24 hours.
C i think becuase in china theres alot of wood importation
Rock layers in order is basically natures calendar.
The highest layer is the newest formed layer
While the deepest layer was the oldest and probably has been there from some time
And everything in between goes accordingly
So putting rocks in order by age helps scientists better understand what was there before what and how the rocks changed over time.
Hope this helps!
Brailiest is always appreciated if you feel its deserved! :)
