earth science help???

Question

can you explain the possible part played by an asteroid in the theory for the mass extinctions at the end of the Mesozoic.

Answer 1

The astroid contained alien species which had goals of world domination. The mass extinctions were the first step in their goal. However, they miscalculated and were killed by their own foolish attempt at genocide. I hope this helped.

Answer 2

An astroid collision with earth would have cast billions upons billions of soot and ash into the air, blanketing the earth from the rays of the sun for years. Not to mention the shock wave and fireball created by the impact. Anything within hundreds of miles of the impact crater would have been vaporized before the astroid ever even touched the surface. It would have been enough to even boil the oceans!

Answer 3

The part that fascinates me ,is there are big rocks out there and traveling a few thousand miles per hour. The other is the comets and they are traveling at near 150,000 mph. The kinetic energy is the velocity squared times the mass. The high speed could very bad.

Answer 4

An asteroid hit the Earth and then the dust from the impact covered the sky. Temperature changes took place and there was less sunlight so plants started to die and then bigger herbivors, who had too little food, started to die and beacause of that larger carnivors had too little food and started to die. It was some kind of a chain effect and it was supposed to contribute to dinosaur extinction.
