what makes a mass extinction different from a background extinction?
Background extinction and mass extinction are similar in that they both involve the disappearance of species due to changes in the environment. They differ, however, in that background extinction tends to be a slow and gradual process, whereas mass extinctions are geologically rapid and catastrophic.
