Answer:
Option A. is correct
Explanation:
Given:
A sediment core is removed from the floor of an inland sea. The sea has been in existence, off and on, throughout the entire time that terrestrial life has existed. Researchers wish to locate and study the terrestrial organisms fossilized in this core. The core is illustrated as a vertical column, with the top of the column representing the most recent strata and the bottom representing the time when the land was first colonized by life.
Solution:
A sediment core refers to a mud collected by the scientists from the bottom of lakes to interpret past ecosystems.
To assign absolute dates to fossils in this sediment core, it would be most helpful if volcanic ash layers were regularly interspersed between the sedimentary strata.
