The mass extinction at the end of the Cretaceous period about 65 mya is believed to have been caused by a massive comet or asteroid smashing into what is now known as the Yucatan Peninsula in the Gulf of Mexico.The debris arising from this impact would have blocked the sun's rays from reaching Earth.How would this cause a mass extinction?

Question

Quizplus · Accepted Answer

The debris from the impact would have caused a massive cloud of dust and debris that would have blocked the sun's rays from reaching Earth. Without sunlight, photosynthesis would have ceased, leading to the rapid die-off of plants. Animals that relied on these plants for food would have also died out, and the impact would have continued up the food chain, ultimately leading to a mass extinction event.
