🌍 Earth is about 4.5 billion years old!
⏳ The geological time scale is like a timeline that tells Earth's history.
🦖 The Mesozoic Era is known as the 'Age of Dinosaurs.'
🌟 There are four main eras: Precambrian, Paleozoic, Mesozoic, and Cenozoic.
🕰️ Fossils act like time capsules that provide clues about ancient life.
🌦️ Climate changes have influenced life on Earth during different eras.
🌊 Tectonic plates move and reshape the continents over time.
🌱 Each era marks significant milestones in evolution and the development of life.
🔬 Scientists use radiometric dating and index fossils to date different eras.
🌈 The future may bring a new era called the Anthropocene due to human impact.
