What is one type of catastrophic change that can cause a mass extinction?
One type of catastrophic change that can cause a mass extinction is an asteroid impact. When a large asteroid collides with the Earth, it can release massive amounts of energy, cause widespread destruction, trigger tsunamis and wildfires, and create a global "impact winter" due to the release of dust and debris into the atmosphere. Such an event is believed to have caused the extinction of the dinosaurs 65 million years ago.
What is the mass extinction?
the holocene extinction
What are mass extinction and background extinction different?
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.
What is a probable cause of two mass extictions?
For all mass extinctions (except the Cretaceous/Paleogene extinction) two probable causes are volcanic eruptions and ocean anoxia.
Discuss the potential disastrous phenomena of global warming and ozone layer depletion?
They both are disastrous. They could cause mass extinction.

Did asteroids cause the mass extinction of dinosaurs?
I think so.
What factors generally cause mass extinction?
The factors that generally cause mass extinction are changes in the natural ecosystem of the species. This may make it difficult for the species to reproduce and to stay alive.
What are 3 reasons for mass extinction?
Mass extinction could occur due to climate change, an asteroid impact and even a volcanic eruption.
What is the effect of mass extinction?
The effect of mass extinction is extinction, death of a mass
How did the coelophysis die off?
The better Q is "What was the cause of the triassic mass-Extinction?"

What are the effects of volcanicity?
volcanic eruptions may cause mass extinctions or volcanic haze.a mass extinction is when a large number of species die out over a short period of geologic time and volcanic haze is when the gases of an eruption cause a haze and block out sunshine, causing a mass extinction.
What are the extinction of animals in the very distant past?
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.
What is the mass extinction?
the holocene extinction
What kind of enviromental changes causes mass extinction?
When human contributes into global warming some animals like polar bears and those who cannot bear heat may cause mass extinction
Is Earth is in danger of another mass extinction?
Mass extinctions occur when the conditions on Earth change faster than species can adapt. Since humans have greatly changed the conditions on Earth and continue to change them at rapid rates, a mass extinction is a likely possibility if nothing is done to reverse or stop the changes (mainly the amount of carbon dioxide being released to the atmosphere). Another common cause of mass extinctions are extraterrestrial which cannot be predicted and are somewhat spontaneous.
