Question

read the passage and answer the following question(s).
dating rock strata
scientists can determine the age of rock layers by measuring radioactive elements within the rock.
radioactive elements found in sedimentary rocks decay quickly, so this method can only date
sedimentary rocks that are less than 50,000 years old.
volcanic rock contains radioactive elements that decay very slowly, so scientists can date volcanic rocks that
are much older than 50,000 years.
a team of scientists is investigating a rock formation found in a region. the diagram shows the rock
formation that the scientists are investigating.

scientists can determine the absolute dates of rock above and below the volcanic layers by using the law of superposition. this law states that younger rock conservation older rock.

Explanation:

The law of superposition is a fundamental principle in geology. It states that in undisturbed sedimentary rock layers, the younger rocks are on top of the older rocks. Since the question is about determining the relative ages of rock layers (younger vs. older) based on their position (above and below), the law of superposition is the relevant concept.

Answer:

superposition
