Question

Quizplus · Accepted Answer

Geological strata are primarily classified by the type of rock they consist of. Different types of rock form under different conditions and can therefore give clues about the environment and events that occurred during the formation of that stratum. Fossils can also be used to help identify strata, but this is not the primary method of classification. The length of time it took to dig through the layer and the moistness of the soil are not relevant factors in classifying geological strata.
