The K-T (Cretaceous and Tertiary) boundary event thought to have been caused by the impact of a large meteorite forming the Chicxulub crater as well as very large scale volcanic activity (in this case the large igneous province known as the Deccan Traps) is a very good example and is thought to have been responsible for the extinction of the dinosaurs.

What are some non examples of mass extinction?
Non-examples of mass extinction include events such as local extinctions, where specific species disappear from a particular area but survive elsewhere, and background extinctions, which occur gradually over time due to normal evolutionary processes. Additionally, events like the decline of a species due to habitat loss or human impact, without affecting the broader ecosystem, do not qualify as mass extinctions. Furthermore, changes in species populations due to climate fluctuations that do not lead to widespread species loss also fall outside the definition of mass extinction.
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
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.
What are two catastrophic events that can cause mass extinctions?
An asteroid from space, and Gradualevents
What are two things that can cause mass extinctions?
ice age,Noahs flood in bible
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.
Do scientists believe that extinctions are uncommon?
No, they are fundamental to the process of evolution. Mass extinctions are less common.

What has happened during mass extinctions?
Bad things

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.
The fossil record indicates that Earth has experienced?
5 mass extinctions
What have Mass extinctions determined?
order in which fossils are found in the fossil record.
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.
