Val Aguilar: Embark on a journey back to Earth’s earliest days, when it was bombarded by huge asteroids. As a geologist, I study the oldest extraterrestrial impact events in the rock record. Together, we'll explore their geologic evidence and their effects on the planet's surface. We'll piece together the story of Earth's survival. These ancient rocks, like time capsules, reveal how natural disasters shaped prehistoric landscapes and influenced the origins of life. Along the way, you'll learn fundamental science concepts, including deep time, stratigraphy, and how rocks form. Get ready to be an Earth detective and uncover clues to our planet's ancient history!
