How does physical evidence, such as rock layers, contribute to our understanding of Earth's history?
It helps predict future climate patterns.
It provides information about ancient human settlements.
It reveals the sequence of events that occurred over time.
It demonstrates the impact of human activities on the environment.
The correct answer is: It reveals the sequence of events that occurred over time.
Physical evidence, such as rock layers, allows scientists to determine the relative ages of the rocks and the fossils they contain. By studying the characteristics and properties of different rock layers, scientists can establish a chronology of events that happened in the past, such as the formation of mountains, the shifting of continents, the eruption of volcanoes, or the deposition of sediments. This information helps in understanding Earth's history and the processes that have shaped it over millions of years.
