Did you know?

Did you know that scientists use a combination of layers of rock, the fossil record, mass extinctions, and the geologic time scale to organize Earth's history? By studying the different layers of rock, scientists can determine the age of the rocks and the events that occurred during that time. The fossil record provides valuable evidence of past life on Earth, helping scientists understand how species have evolved and changed over time. Mass extinctions, such as the extinction of the dinosaurs, mark significant events in Earth's history and allow scientists to track major shifts and changes. The geologic time scale is a framework that organizes Earth's history into different time periods, making it easier for scientists to communicate and study past events.
