Within the world's undisturbed sequences of sedimentary rocks,fossils ____________. 
A) are rarely, if ever, found 
B) are randomly distributed 
C) occur in an ordered sequence

Quizplus · Accepted Answer

Fossils in undisturbed sequences of sedimentary rocks occur in an ordered sequence known as the law of superposition. This means that the oldest fossils are found in the deepest layers of rock, and the youngest fossils are found in the highest layers. This ordered sequence allows scientists to create a timeline of the evolution of life on Earth based on the fossils found in these rocks.
