Question

What do scientists look for in order to correlate rocks in different locations? A.Different rock types and similar fossils B.Many rock types and many fossils C.Similar rock types and lack of fossils D.Similar types and similar fossils

Answer 1

Option (A)

Step-by-step explanation:

The correlation of rocks is usually defined as a technique that helps in determining the age of the rocks that are mostly characterized by the presence of similar fossil/fossil assemblages. These fossils that are used are mainly the index fossils that appeared for a short geological time and were very widely distributed on earth's surface. By determining the age of these fossils, the rocks in which these fossils are found were concluded to be formed during the same age.

This method is efficient to use for the geologists where the fossils acts as a tool to determine the age of the rocks. For the correlation of rocks, scientists look for a similar type of fossils that are found in different places.

Thus, the correct answer is option (A).
