Geologic History

Geologic history is the timeline of Earth's formation and changes over billions of years. It begins with Earth's origins about 4.6 billion years ago, when it formed from dust and gas. Over time, Earth's surface and interior evolved, creating mountains, oceans, and continents. Key events include volcanic activity, shifting landmasses, and climate changes, shaping the planet's geology. Fossils and rock layers help scientists understand this history, revealing life’s evolution and environmental shifts. Studying geologic history helps us understand Earth's past processes, how landscapes formed, and the natural forces that continue to shape our world today.
