question 6 of 10
which principle states that animals succeed each other in a definite sequence?
a. faunal succession
b. cross - cutting relationships
c. uniformitarianism
d. original horizontality

Explanation:

• Option A: Faunal succession is the principle that fossil organisms succeed one another in a definite, recognizable order.
• Option B: Cross - cutting relationships deal with the relative ages of rock layers and features that cut through them, not animal succession.
• Option C: Uniformitarianism is about the present - day processes being the same as those in the past, not animal succession.
• Option D: Original horizontality states that sedimentary rocks are originally deposited in horizontal layers, not related to animal succession.

Answer:

A. Faunal succession
