Q Which of the following is the leading theory for the extinction of the dinosaurs?
- A They were wiped out by stronger animals.
- B A large asteroid collided with Earth.
- C An epidemic disease spread.
B A large asteroid collided with Earth.
The extinction of the dinosaurs is believed to have been caused by an asteroid impact.
About 66 million years ago, a massive celestial body roughly 10 kilometers in diameter collided with Earth.
The impact triggered fires and tsunamis, and the resulting dust and debris covered the globe, blocking sunlight for a long period. This led to global cooling and ultimately the mass extinction of the dinosaurs.
