how would a geologist use absolute dating to determine the age of sedimentary layers? by dating the age of several radioactive elements in a sedimentary rock layer by dating the age of intrusions and extrusions near a sedimentary rock layer by comparing the relative ages of several sedimentary rock layers by identifying fossils in nearby intrusions and extrusions and determining their age

how would a geologist use absolute dating to determine the age of sedimentary layers? by dating the age of several radioactive elements in a sedimentary rock layer by dating the age of intrusions and extrusions near a sedimentary rock layer by comparing the relative ages of several sedimentary rock layers by identifying fossils in nearby intrusions and extrusions and determining their age

Answer

Brief Explanations:

Absolute dating of sedimentary layers is often done by dating the age of intrusions and extrusions near a sedimentary rock layer. Intrusions and extrusions are igneous - rock formations that can be dated using radiometric dating techniques. The sedimentary layers must be younger than the intrusions and extrusions that cut through them.

Answer:

by dating the age of intrusions and extrusions near a sedimentary rock layer
