Question #N516
The history of the Earth can be understood by studying the rock layers found beneath the surface. These layers, called strata, are formed over millions of years as sediment is deposited and compressed. By examining the strata, scientists can learn about the history of life on Earth, the climate of the past, and the geological events that have shaped the planet. The relative ages of different strata can be determined using a principle called the principle of superposition, which states that in an undisturbed sequence of sedimentary rocks, the oldest layers are at the bottom and the youngest layers are at the top.
According to the passage, what is the most likely reason why scientists study rock layers?Correct Answer is: B
The passage states that by studying rock layers, scientists can learn about the history of life on Earth, past climates, and geological events. This is the most likely reason why scientists study rock layers.
