In which situation will older rock layers lie above younger rock layer?

• Rock layers have been overturned by folding - plate tectonics

• Erosion has exposed older rocks, and new layers have been deposited

• Sedimentary rock layers have remained undisturbed after deposition

• Igneous intrusions have cut through layers of sedimentary rock.

Unless a layer of rocks has been overturned or shifted, the bottom rock layer:

• has fossils

• is the oldest

• has the greatest amount of minerals

• has the hardest rocks
