A) Model A
B) Model B
C) Model C
2. In the two photographs below, A is of structures within a modern sand dune that are
identical to the structures in the sandstone shown in B. Geologists interpret the structures
in the ancient sandstone to be formed by the same processes as those that produced the
structures in the modern sand dune. Geologists' ability to interpret these structures by
comparing them to modern processes is an example of
