Where did the asteroid strike the Earth approximately 66 million years ago, leading to mass extinction?
Answer
The Yucatan Peninsula
The Chicxulub impact, which took place 66 million years ago, was centered in the Yucatan Peninsula of Mexico. This collision released energy equivalent to billions of tons of TNT, ejecting massive amounts of aerosols and dust into the atmosphere. This atmospheric contamination blocked sunlight for years, causing a global collapse of photosynthesis and food chains that wiped out the non-avian dinosaurs.
