The Catastrophic End of the Dinosaurs

The video explains the extinction of dinosaurs, which thrived for 165 million years until a catastrophic event 65 million years ago. An asteroid hit the Yucatan Peninsula, creating a massive crater and causing global shock waves, tsunamis, and fires. The impact threw debris into the atmosphere, blocking sunlight and cooling the Earth. This environmental shift led to the extinction of many species, including dinosaurs, as they could not adapt to the new conditions.
