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 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 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.
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
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.
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 have Mass extinctions determined?
order in which fossils are found in the fossil record.
The fossil record indicates that Earth has experienced?
5 mass extinctions
What are two catastrophic events that can cause mass extinctions?
An asteroid from space, and Gradualevents
