_____________ is the belief that the same processes that changed the Earth in the past, continue to work in the same way today to change Earth and will continue to change the Earth in the same way in the future.

A(n) _____________ is the trace remains of an organism that lived long ago, most commonly preserved in sedimentary rock.

The weather conditions in the area over a long period of time refers to

A fossilized structure that formed in sedimentary rock by animal activity on or in soft sediment is considered a(n)

This happens when an organism's tissues are replaced by minerals; or refers to the process by which organic matter exposed to minerals over a long period of time turned into a stony substance.

_____________ is a piece of fossilized animal dung.
