fossils that are used to estimate the absolute age of the rock layers in which they are found

Check ALL that apply:

Which of the following features does a good index fossil need?

Which of the following is NOT an example of a trace fossil

Which image represents tilting - when Earths forces move rock up or down unevenly

Which image represents folding - the bending of rock that happens when rock layers are squeezed together

Which image represents faults - a break or crack in Earth’s crust where rocks can move

Which image represents intrusion - igneous rock that forms when magma is injected into rock and then cools

the principle that younger rocks lie above older rocks if the layers have not been disturbed

an ordered arrangement of rock layers that is based on the relative ages of the rocks, with the oldest rocks at the bottom of the column

if a fault or other body of rock cuts through another body of rock then it must be younger in age than the rock through which it cuts and displaces.
