Asteroid Impact Effects and Evidence

The video explores the violent history of Earth's solar system, focusing on impact craters as evidence of past asteroid collisions. It highlights a significant impact in Mexico 65 million years ago, believed to have contributed to the extinction of dinosaurs. The aftermath of such impacts, including seismic activity and atmospheric changes, had profound effects on Earth's environment.
