Based on Internet research using the principle of Uniformitarianism analyze the events following the asteroid impact at the end of Cretaceous which killed dinosaurs. Sixty-six million years ago, the massive Chicxulub asteroid slammed into Earth, setting off a chain of events that wiped out the dinosaurs and countless other species. soon after the asteroid struck, the planet was plunged into a short but devastating "impact winter" that would have darkened the sky, cooled Earth and inhibited photosynthesis. Based on the internet research discuss how a similar event would impact humans in modern times whether it would cause extinction of humans and in which way it would resemble extreme climate change scenarios
