What is the mass extinction?
the holocene extinction
What is one gradual change that can cause a mass extinction?
One gradual change that can cause a mass extinction is climate change. If the Earth's temperature rises or falls significantly over time, it can disrupt ecosystems and lead to the extinction of many species that are unable to adapt quickly enough to the new conditions. This can result in a cascading effect on other species within the ecosystem, ultimately leading to a mass extinction event.
How does the current or sixth mass extinction differ from the past five mass extinction events The sixth mass extinction is believed to be caused by human-related factors. The sixth mass extinction is?
The sixth mass extinction differs from the past five primarily because it is driven by human activities, such as habitat destruction, climate change, pollution, and overexploitation of species. Unlike previous extinctions that were caused by natural events like volcanic eruptions or asteroid impacts, the current crisis is a result of anthropogenic influences that accelerate species loss at an unprecedented rate. Additionally, the current extinction event is occurring within a much shorter time frame, with species disappearing faster than ever recorded in the fossil record. This human-induced crisis poses significant challenges for biodiversity and ecosystem stability.
How are fossils used to show mass extinction?
Fossils provide critical evidence of mass extinctions by documenting the sudden disappearance of numerous species from the geological record. Paleontologists analyze fossil layers to identify patterns of biodiversity loss and correlate these with catastrophic events, such as asteroid impacts or volcanic eruptions. By comparing the abundance and diversity of fossils before and after these events, researchers can quantify the extent of extinction and understand the ecological impacts. This fossil evidence helps to illustrate the rate and scale of species loss during mass extinction events in Earth's history.
What is a synonym for mass extinction?
Catastrophic extinction event.
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 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 the mass extinction?
the holocene extinction
What factors generally cause mass extinction?
Factors that generally cause mass extinction include natural disasters (such as asteroid impacts or volcanic eruptions), climate change, environmental changes, and human activities like deforestation, pollution, and habitat destruction. These factors can disrupt ecosystems and lead to the widespread extinction of various species.
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.
