What is the difference between a mass extinction and a regular (background) extinction? Mass extinction can be caused by ecological factors like climate change and loss of habitat. Mass extinction involves many species over a short period of geologic time. Mass extinction is ongoing and is a regular process that results from evolution. Mass extinction occurs over a long period of time.
