meteor impact theory

The meteor impact theory suggests that many significant events in Earth's history, such as mass extinctions, were caused by large space rocks called meteors or asteroids colliding with our planet. When a meteor strikes Earth, it releases a massive amount of energy, creating craters and causing widespread environmental changes. For example, the impact believed to have contributed to the extinction of the dinosaurs 66 million years ago released dust and aerosols into the atmosphere, blocking sunlight and disrupting ecosystems. This theory helps explain sudden changes in Earth's climate and biological diversity throughout geological history.
