The effect of mass extinction is extinction, death of a mass
There were five major extinction events in the past. They are called the Cretaceous-Tertiary (or K-T) extinction event, the late Devonian mass extinction, the Permian mass extinction, the Ordovician-Silurian mass extinction and the Triassic-Jurassic mass extinction event.
the holocene extinction
The dinosaurs fell victim to a mass extinction.
This would be called a mass extinction or mass die off.This would be called a mass extinction.
540 million years ago was the first mass extinction
We are still not sure what caused the mass extinction of the dinosaurs, though an asteroid impact seems to be the popular theory.Scientists believe we may be heading towards another mass extinction event.
Mass depletion is an event in which extinction rates are higher than normal but not high enough to be classified as a mass extinction.
Mass extinction - More than 50% of the population went extinct in a short period of time.Background extinction - An average rate of extinction occurred during a given time period.
Mass extinction is when many animals go extinct within a short period of time caused by the same variables/factors leading to the mass extinction.
The Permian mass extinction occurred about 248 million years ago and was the greatest mass extinction ever recorded in earth history exterminating more than 95% of all life on EarthTwo theories have been proposed - the impact of a huge meteorite or comet over 10 kilometres in diameter, or a massive and prolonged volcanic eruption. The volcanic theory appears to be taking the lead at the present time.
