Combined study of rocks and fossils reduces which limitation in understanding Earth evolution?

Answer and explanation

Correct answer: Dependence only on guesswork

The governing principle is evidence-based reconstruction of the past. Rocks preserve information about ancient environments, mineral formation, volcanic events and changes in the crust, while fossils record the organisms that lived in particular periods and environments. When both types of evidence are studied together, geographers can compare physical conditions with biological history and make more reliable inferences about Earth evolution. Therefore, option A is correct: the combined evidence reduces dependence on unsupported guesswork. Options B, C and D are features or measurements that may be studied separately, but they are not the principal limitation removed by examining rocks and fossils together.
