Geologic Time Scale

Real World Example

Imagine trying to organize a huge photo album of your entire life, where each photo represents a significant event or change. This is similar to how geologists organize Earth's history into a timeline based on major changes and events that have occurred over billions of years. Just as you might categorize your photos by memorable moments like birthdays or vacations, geologists categorize Earth's history into different periods based on significant geological events, such as mass extinctions or the formation of mountain ranges, creating a structured timeline that makes sense of the planet's vast and complex past.
