Giant Impact!


Giant Impact!

An asteroid or comet, 10 to 16 kilometers in diameter, struck Earth in what is now the Yucatán Peninsula of Mexico. This impact is thought to have triggered fires and tsunamis and created a cloud of dust and water vapor that enveloped the globe in a matter of days, resulting in fluctuating global climate changes. The extreme environmental shifts would have caused a mass extinction of 75% of Earth's species, including the dinosaurs.
