MASS EXTINCTION IS THE DISAPPEARANCE OF A LARGE NUMBER OF THE EARTH’S SPECIES. THE MOST DEVASTATING EXTINCTION WAS AT THE END
OF THE PERMIAN PERIOD; AN ESTIMATED 95% OF MARINE SPECIES AND 60% OF INSECTS DISAPPEARED ABOUT 245 MILLION YEARS AGO. HUGE
VOLCANIC ERUPTIONS CONTINUED FOR THOUSANDS OF YEARS AND CAUSED DESTRUCTION AND DUST THAT BLOCKED THE SUN. IT CAUSED GLOBAL
COOLING THAT FROZE THE WATER’S SURFACE.
THE MOST FAMOUS MASS EXTINCTION WAS IN THE END OF THE CRETACEOUS
PERIOD, WHEN THE DINOSAURS AND MANY OTHER PLANTS AND ANIMALS
DISAPPEARED AND UP TO 75% OF ALL MARINE LIFE DIED. IT OCCURRED 65 MILLION YEARS AGO. A THEORY SAYS THAT A BIG ASTEROID WITH A
DIAMETER OF 10KM HIT THE PLANET AND CREATED A GIANT CLOUD OF ROCKS, DUST, AND SULFUR IN THE AIR THAT BLOCKED THE SUNLIGHT.
CATASTROPHIC CLIMATE CHANGE DID NOT LET DINOSAURS SURVIVE.
