What is one gradual change that can cause a mass extinction?
The Hallicigenia Apeared in the Cambrian Peirod.
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 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 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.
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 geological events happened in the Cambrian time?
the mass extinction
Why is there correspondence between mass extinction and the ends of geological periods?
Because mass extinction events marked the loss of a number of a species to fill the available ecological niches, these events correspond to geological period boundaries.
What is some catastrophic events that caused periods to come to an end?
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 is the effect of mass extinction?
The effect of mass extinction is extinction, death of a mass
Is the Devonian time before or after the mass extinction?
Which mass extinction? There have been five such events. The first one, the Ordovician-Silurian extinction event occurred before the Devonian. The Late Devonian event occurred during the Devonian. All other mass extinctions occurred after the Devonian.
How did the coelophysis die off?
The better Q is "What was the cause of the triassic mass-Extinction?"

What is one gradual change that can cause a 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.
