Dinosaur News : Asteroid Kills Dinosaur Causes Long Darkness On Earth That Led To The Extinction Of Life

Written by admin
Millions of years ago, giant dinosaurs ruled the earth. The remains show that these dinosaurs were up to 130 feet long and weighed up to 77 tons. Then one day suddenly the rain of asteroids from space ended the existence of the dinosaur species walking on the ground. But after this event, the earth remained submerged in darkness for a long time. The fall of the asteroid caused forest fires and ash, dust and smoke filled the sky, blocking sunlight reaching Earth.

A new research has found that the years following the asteroid’s event were fueling an ‘extinction wave’, reports Live Science. The cataclysms that came after the collision of asteroids about 60 million years ago had destroyed many forms of life. This collision also gave rise to several environmental changes that over time added to the wave of mass extinctions. One reason for the extinction wave is believed to be a dense cloud of ash and particulate matter that spread through the atmosphere.

life on earth was over
These clouds covered the Earth and darkened many parts of the planet. For two years these clouds remained in the sky. During those times the process of photosynthesis had failed due to which the ecosystem collapsed. 16 at the annual meeting of the American Geophysical Union (AGU), held in New Orleans and online, the decline was likely to persist for decades, even after sunlight returned.

12 km wide asteroid collided with earth
The Cretaceous Period (145 million to 66 million years ago) ended with a terrifying bang when an asteroid traveling at about 27,000 mph (43,000 km/h) collided with Earth. It was about 7.5 miles (12 kilometers) in diameter which left a crater known as Chicxulub Crater. It is located under water in the Gulf of Mexico near the Yucatan Peninsula and extends at least 90 miles (150 km) in diameter.
