A mass extinction is an abrupt decrease in life on earth due some catastrophic event.
- The collision of a large bolide on the surface of the earth is a catastrophe in itself.
- The collision and its aftermath have destructive consequences on life.
- The force of the collision can reverberate in form of vibration throughout the earth.
- It can cause heating of the earth surface.
- Volcanic eruptions can become global phenomenon that upsets the earth balance.
