29) The Cretaceous extinction. which was the most recent mass extinction, occurred about 65.5 million years ago. What is the leading hypothesis to explain the Cretaceous extenction? A) The Indian sub-continent collided with the Asian techtonic plate, giving rise to the Hymalayan mountains which altered the jet stream and caused the planet to enter an ice age B) An asteroid about 6 km in diameter collided with Earth, which vaporized the caribbean ocean, set fire to north and south America, and expelled enough dust into the atmosphere to block the sun enough to result in a winter like environment all across the globe for several years C) A new group of predators evolved that were significantly better at capturing prey, to the point that they drove many species (including other predators and eventually themselves) to extinction D) Massive amounts of volcanic activity released tons of CO2, enough to significantly increase the temperature of the planet 30) The Permian extinction, which was the second most recent mass extinction, occurred about 251 million years ago.
