loss of habitat (change of habitat, turns too cold, too hot, too dry, too wet, ect)
loss of food (where we lose almost all plants and the in tire food chain collapses. along with us)
disease (self explanatory)
freezing (earth freezes over into another ice age)
flooding (after ice age effect the ice melts)
comets (the ash covers sun and kills plants. Same thing with loss of food except the ash can also possibly choke us)
super volcanoes (the ash covers sun and kills plants. Same thing with loss of food except the ash can also possibly choke us)
another animal claims the top of the food chain (mostly sci-fi)

What was the outcomes of each of the mass extinctions?
The outcomes of each of the mass extinctions is that animal and/or bacteria die.
Mass extinctions create conditions that promote?
Adaptive Radiation
The death of many species in a short time known as what?
The death of many species in a short amount of time is known as a mass extinction event. These events can be caused by a variety of factors such as natural disasters, climate change, or human activities. Mass extinctions have occurred several times throughout Earth's history.
What caused the last 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.
What is it called in particular when a high percentage of the species on earth dies off at a particular time?
These are called "mass extinctions", and there have been five such events (that we know of) on the Earth. These are generally caused either by astronomical impact events (such as the asteroid that killed off the dinosaurs 65 million years ago) or massive volcanic activity. The causes of these extinctions has been a matter of some dispute, since they happened so long ago.
What might have caused mass extinctions?
Mass extinctions can be caused by a variety of factors, including volcanic activity, asteroid impacts, climate change, and changes in sea levels. These events can disrupt ecosystems and lead to widespread loss of species.
What affects have mass extinctions had on the history of life?
Mass extinctions have had a profound impact on the history of life by dramatically altering the diversity and composition of species. They have caused major shifts in ecosystems and have created opportunities for new species to evolve and adapt. Additionally, mass extinctions have played a key role in shaping the evolutionary trajectory of life on Earth.
What was the outcomes of each of the mass extinctions?
The outcomes of each of the mass extinctions is that animal and/or bacteria die.
What has caused most of the mass extinctions on earth?
Mass extinctions are caused by rapid, global changes. Usually these are changes in climate. Without the right temperatures and precipitation, plants that animals depend on die out, which wipes out the animals. Examples include the Permian-Triassic Extinction, where volcanoes in what is now Siberia caused intense global warming, wiping out over 90% of species, and the K-T Extinction, where an asteroid impact suddenly blocked sunlight for months or years, killing off the dinosaurs and many other organisms.
Do scientists believe that extinctions are uncommon?
No, they are fundamental to the process of evolution. Mass extinctions are less common.
What are some of the causes of background and mass extinctions?
Background extinctions are typically caused by natural events such as climate change, volcanic eruptions, or asteroid impacts. Mass extinctions are often attributed to catastrophic events like major asteroid impacts, volcanic eruptions, or significant climate change, which cause widespread disruption to ecosystems and species. Human activities, such as habitat destruction, pollution, and overexploitation of resources, can also contribute to both background and mass extinctions.
What has happened during mass extinctions?
Bad things
Why mass extinctions occur and why they often mark divisions of geologic times?
Mass extinctions occur when extreme temperatures happen.https://science.howstuffworks.com/life/evolution/extinction3.htm
Why do you think most extinction's occur as background extinctions?
Most extinctions occur as background extinctions because they are longer time periods unlike the shorter mass extinctions which there were only two in the Paleozoic era, the Ordovician mass extinction, and the Permian/Triassic extinction in which 95% of all marine animals became extinct
Mass extinctions create conditions that promote?
Adaptive Radiation
What has changed most of the mass extinctions on earth?
climate change
Mass extinctions are usually followed by what?
Mass extinctions are usually followed by a period of rapid diversification as surviving species adapt to new environmental conditions and fill ecological niches left vacant by extinct species. This diversification can lead to the emergence of new species and ecosystems over time.
