It is believed that the same asteroid that hit the Earth 66 million years ago caused magma to appear on the bottom of the ocean. Can you believe that? The research was shown in Science Advances and it can change the way we see the disaster.
Here’s the main theory
Ever since we were kids we learned that an asteroid hit the Earth and this lead to the extinction of dinosaurs and other species from our planet. This extinction was known as Cretaceous-Paleogene, name that came from the 2 periods, before and after the event. This whole thing is believed to have left a huge crater and some debris clouds, which obscured the Sun.
One volcanic area the largest, actually, India, and it was the gangbusters when it all happened. The Deccan Traps are actually what killed the dinosaurs. The gases from it, to be exact.
So which one was it? The gases or the asteroid?
Some studies showed that the traps have actually erupted million years before the asteroid hit the planet.
But maybe they were connected somehow. Maybe the asteroid was the one that made the Deccan Trap volcanism to burst, a thing that leads to the disparition of the most interesting species that ever lived on Earth. And it can be possible if the asteroid really had a major impact on the traps at that time. This should’ve been shown in the activity of the Earth’s mid-ocean ridges.
What are mid-ocean ridges?
These are some gaps in the crust of the Earth from the bottom of the oceans and are usually a sign of the point where tectonic plates meet. When they pull apart, there is magma, flows out and creates new seafloors.
