Answer to Question 1

Answer: The principle of lateral continuity states that sedimentary beds are continuously deposited over large areas until some sort of barrier limits deposition. The principle of faunal succession states that fossils found in rocks change through time as some species become extinct and new ones appear. Each species of organism has a limited time interval of existence. Fossil-bearing rocks are placed in relative age order by determining the interval of geologic time represented by the fossils that the rocks contain.

Answer to Question 2

Answer: The geologic time scale is a series of intervals with an established chronological order. The fossils that are found in rocks deposited during that time define each named interval. It is helpful because scientists can infer from what time period an organism (fossil) may have lived based on sedimentary rock layer.
