Video Transcript:
when the asteroid struck most of the impact energy was deflected out or up only one percent of the force traveled down into the ground but it's enough to ring the planet like a bell seismic waves radiate across and through the earth 16 minutes and 40 seconds later they reach the pacific northwest the valley shakes as a magnitude 11 earthquake ripples through the ground triceratops panic at the edges of the valley in their desperate attempt to escape the tremors and falling debris smaller animals take shelter underground meanwhile the ejecta cloud approaches at 16 000 kilometers per
hour baking the earth with unrelenting heat millions of volts of static electricity charge the cloud like a giant battery creating a vast electrical storm superheated rocks shower the valley in a burning hail the quetzalcoatlus managed to flee the devastation caused by the quake but there's no way to hide from a rain of fire only the valley floor can provide shelter and they're too big to descend quickly eventually the male's tattered wings can no longer keep him aloft if his mate doesn't find shelter soon she'll be next on the mountain slopes two triceratops emerge above the
cool sea mist they're almost out of the quake-ravaged valley when the ejecta cloud arrives just hours ago north america was a dinosaur paradise now it's a living hell the ejecta cloud continues its spread across the globe but the effects it has on the ground vary dramatically twelve thousand kilometers away in mongolia the cloud rolls in silently from the east temperatures on the ground creep upwards a few degrees hotter every second there's no audible warning for the creatures here only the mounting heat as the air reaches 50 degrees celsius their only hope is shelter at 70
degrees survival is measured in minutes and at over 90 degrees in mere seconds 90 minutes after impact the temperature on the ground in mongolia peaks at 150 degrees celsius
