How do most fossils form?

• An insect becomes trapped in amber.

• An entire organism becomes frozen in ice.

• A dead organism becomes buried in sediment.

• A dead organism becomes buried in tar.

What evidence is most important when using relative dating?

• the half-life of a radioactive element

• the position of sediment in petrified rock

• the types of minerals in a petrified fossil

• the position of fossils in sedimentary rock layers
