why dinosaurs are extinct
Answers
Explanation:
Volcanic eruptions that caused large-scale climate change may also have been involved, together with more gradual changes to Earth's climate that happened over millions of years. Whatever the causes, the huge extinction that ended the age of the dinosaur left gaps in ecosystems around the world.
Geological evidence indicates that dinosaurs became extinct at the boundary between the Cretaceous and Paleogene eras, about 66 million years ago, at a time when there was worldwide environmental change resulting from the impact of a large celestial object with the Earth and/or from vast volcanic eruptions.
Answer:
Another widely known theory is that a series of volcanic eruptions caused the extinction of the dinosaurs. Scientists have found lava flows in India that provide evidence of volcanic activity greater than humans have ever seen. Volcanic eruptions would have sent dust and ash into the atmosphere.
