Extinction
From Wikipedia, a free encyclopedia written in simple English for easy reading.
Extinction is when there is none of a certain animal left. This can be caused by habitat loss or by being overhunted. An example of an animal that is extinct is the Dodo. An animal that is endangered has a good chance of becoming extinct.
When talking about volcanos, extinct means that the volcano is no longer active.
