There have been five main mass extinctions. Match each mass extinction event to its description.
1.
Permian extinction
2.
Cretaceous-Tertiary extinction
3.
Triassic extinction
4.
Devonian extinction
5.
Ordovician extinction
a.
This extinction was most likely due to a change in sea level. During this event, about 60% of all marine species were eliminated.
b.
This is the best-known mass extinction. It eliminated most large animals, including the dinosaurs.
c.
This was the most severe extinction event. About 96% of life on Earth died during this event.
d.
This extinction was most likely caused by climate change. About 80% of land animals died during this event.
e.
This extinction was most likely due to a change in sea level. It especially affected coral reefs.
The fossil record shows that in just the last 600 million years, there have been five instances of sharp decreases in the diversity and abundance of living organisms. what are these events?
a. droughts
b. mass extinctions
c. reversals of the earth's magnetic field
d. great migration
A. How do you compare the diversity of population between the main landand an island?B. How do the mechanisms of evolution contribute to the extinction ofother organisms?
