Catastrophic Event
An asteroid impact is a rock that is heading towards somewhere with burning hot speed and hits its target.
The local effects of this is dying of impact, habitat destruction, and the forceful vibration of the impact. Global effects include huge impact, the killing of a species, long range habitat destruction. This happened during the Mesozoic Era. |
Volcanic activity is the activity where volcanoes are active and lava spills out everywhere. Local effects are ash clouds covering up the sky which leaves no sunshine for the plants, or animals, lava could destroy homes and habitats. Global effects are acid rain clouds over the ocean, ash clouds covering the sky for miles and miles and miles long. This happened in the Cambrian time, it was called the Cambrian Explosion.

Climate change is when there's a change in the environment around us, but it's not human made its environmental.
Climate Change effects the food chain because if it starts changing then some of the animal species could die out because they wouldn't be fit for that kind of change.
