A geologist observes glacial moraines and striations in an area that is today not glaciated. The geologist interprets those features as evidence of past glacial activity. He or she is utilizes all of the following except:

a. middle-level theory.
b. the principle of uniformitarianism.
c. a relational analogy.
d. knowledge of contemporary glacial processes
e. confidence that the features observed do not represent evidence of past glaciers.

Question 2

In geology, the principle of uniformitarianism asserts

a. that the processes that modified the earth's surface in the past are unknowable because they cannot be directly observed.
b. that the processes now operating to modify the earth's surface are the same as those of the geologic past.
c. that the processes now operating to modify the earth's surface cannot simply be assumed to be the same as those of the geologic past, but must be demonstrated to be the same.
d. that geologic processes are distinct from archaeological processes and that uniformitarianism only applies to geologic processes.
e. that unlike geologists, archeologists must look to the contemporary world to provide them with hypotheses that account for the formation of physical remains.
