A newly published study shows that the asteroid that ejected the dinosaurs also acidifies the Earth's oceans.
The study looks at the newly discovered evidence of millions of years of fossilized algae known as foraminifera. Experts have analyzed the chemical element boron to show in detail how devastating the asteroid impact is, hoping to stop the debate that other natural disasters – such as a massive eruption of a volcano – have led to the death of dinosaurs.
The rise of ocean acidification, an event that would take "millions of years" to restore the oceans and planet, was devastating, experts said. "Our data suggest that impact, not volcanism, was key to driving the mass extinction of extreme chalk," the study summary reads.
MINUTES OF MINUTE ACCOUNTS AS ASTEROID THAT DYNOSAURES DIVASTATED LANDS
Scientists examined clay samples from an underground cave in the Netherlands for their research, a cave that contained "a particularly thick layer of clay from the immediate impact of the impact," Henan said, adding that it was "really quite rare."
The newly discovered findings appear to be some of the most definitive evidence found about what led to the extinction of dinosaurs and how quickly it happened as sulfur dioxide exploded into the atmosphere, eventually causing acid rain.
"Our data speak to the gradual deterioration of environmental conditions 66 million years ago," added Henehan.
The find is also the first direct link between the disappearance of dinosaurs and the sharp rise in the pH levels of the oceans, Henan went on.
"For years, humans have suggested that there will be a decrease in the pH of the ocean, since a meteor strike struck sulfur-rich rocks and caused sulfuric acid to spill, but so far no direct evidence has shown that this has happened. . "

The study was published in Proceedings of the National Sciences of in Mexico and is now known as the Chicxulub Crater, it has obliterated nearly 75 percent of all species on the planet.
A separate study published in January suggested that the impact of the cosmic rock also caused a worldwide tsunami. reached more than 5,000 feet in the air.
