Asteroid Impact Theory

The Asteroid Impact Theory suggests that a large asteroid collided with Earth around 66 million years ago, creating a massive crater known as the Chicxulub crater in present-day Mexico. This impact released enormous energy, causing widespread wildfires, a "nuclear winter" effect with blocked sunlight, and drastic climate changes. These environmental disruptions led to the mass extinction of many species, including the dinosaurs. The theory is supported by evidence such as iridium-rich layers in the Earth’s crust, impact crater findings, and shocked minerals, confirming that an extraterrestrial object played a significant role in this global event.
