Answer:
Scientists can come up with a hypothesis that the rocks from two different quarries probably formed at the same time though they are separated by a distance of 50km by the help of the correlation method.
Correlation is defined as the interconnection between two objects that might have formed at the same time but at different places. Similar rock composition and quarries may be present which are likely to form under certain geologically suitable conditions. This gives the idea that the rocks with quarries might have formed at the same time and due to the processes of weathering and erosion, the rocks got separated.
This method is usually implemented in order to determine the age of similar rock strata occurring at two different places.
