The Slow Fade: Background vs Mass Extinction

Species go extinct every day. That is a normal, ongoing feature of life on Earth, and it always has been. But occasionally, extinction rates spike so far beyond the background that the entire biosphere gets restructured in a...

Questions: 20 | Attempts: 10 | Last updated: Mar 8, 2026

Sample Question 1
What is the "background" rate of extinction?

The normal, low rate of species loss over a long period

A sudden disappearance of all life

The extinction of only dinosaurs

The growth of new species

The way animals move to new homes

Sample Question 2
In the study of background vs mass extinction, mass extinctions are much faster and more destructive than background extinctions.

True

False

Sample Question 3
When comparing background vs mass extinction, what usually causes background extinction?

Natural competition and slow environmental changes

Giant asteroids from space

Massive volcanic eruptions covering the whole planet

The sun turning off

Global ice ages that happen in one day
