Ejecta Cloud Effects on Environment

The video describes the catastrophic effects of an asteroid impact on Earth. Initially, most of the impact energy is deflected, but enough travels into the ground to cause seismic waves that reach the Pacific Northwest, resulting in a magnitude 11 earthquake. Animals, including triceratops and Quetzalcoatlus, react to the tremors and the approaching ejecta cloud, which brings intense heat and electrical storms. The cloud spreads globally, dramatically affecting temperatures, especially in Mongolia, where survival becomes impossible as temperatures peak at 150 degrees Celsius.
