The ________ is the idea or concept that ancient life forms succeeded each other in a definite, evolutionary pattern and that th
e contained assemblage of fossils can determine geologic ages of strata? a. principle of superposition
b. law of horizontality
c. law of cross-cutting relationships
d. principle of faunal succession
The answer is D. In a
geological era, when the plants and animals
in the then environment die, they get buried
in sediments. These sediments are covered
by other sediments of another geological
time within which are the remains of dead species
of the then geological era. These sediments from different geological times have different properties hence
form visible strata that can be studied to identify the kind of environment in the then geological time. Their
fossils can also be studied to identify
the kind of species that roamed the earth during the time.
