Mass extinctions occur when extreme temperatures happen.https://science.howstuffworks.com/life/evolution/extinction3.htm
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.

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.
The outcomes of each of the mass extinctions is that animal and/or bacteria die.
No, they are fundamental to the process of evolution. Mass extinctions are less common.

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

5 mass extinctions
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.
