As part of a new study, the specialists from Imperial College London created an unusual computer simulation that made it possible to find out what caused the mass extinction of the dinosaurs. They took the day of the "fall of the dinosaur asteroid." That historical event for the planet occurred 66 million years ago. The space object collided with our planet on the territory of the Yucatan Peninsula, leaving behind the legendary Chiksulub, the largest crater on the Earth.
For a long time it was believed that this event changed the world, and life for the dinosaurs ended. Many species died, except those that became birds. But over time, the scientists have considered other versions of the changes that occurred on the planet.
For example, powerful volcanic eruptions that led to the death of 75% of life on Earth. Now a research team from Imperial College London, the University of Bristol and University College London has proved that only the impact of an asteroid could create conditions that are unfavorable for the dinosaurs. A researcher Alessandro Chiarenza reported on the main facts of the study.
They are related to the fact that the impact of the asteroid formed winter cold for many decades, and that these environmental impacts devastated a suitable habitat for the dinosaurs. But if we compare these consequences with the volcanic ones, then the latter lose a lot. Intense volcanic eruptions were not strong enough to significantly destroy global ecosystems and affect the lives of large organisms such as dinosaurs.
If this was actually an asteroid impact, then dust particles and gas rose high into the atmosphere, blocking the Sun for many years. It caused a sharp cooling, unacceptable to the dinosaur organisms. Volcanic eruptions also produce particles and gases with solar blocking effects.
But they cannot be so long as to change life on the planet so dramatically. The use of computer simulations confirmed that only an asteroid impact destroyed all potential dinosaur habitats, and the actions of volcanoes left some viable areas around the equator.
