how is radioactive decay used to date sedimentary rocks?\no the amounts of potassium and argon in sedimentary rocks are measured.\no the amounts of unstable elements in each layer of the sedimentary rocks are compared.\no the amounts of unstable elements in the volcanic layers above and below the sedimentary layers are measured.
Answer
Brief Explanations:
Sedimentary rocks are hard to date directly. Volcanic layers above and below can be dated using radioactive decay. The ages help date sedimentary layers.
Answer:
The amounts of unstable elements in the volcanic layers above and below the sedimentary layers are measured.
