Why do we think most extinctions occur as background extinctions?
Most extinctions are believed to occur as background extinctions because they result from gradual changes in environmental conditions, competition, and ecological shifts rather than catastrophic events. These slow processes allow species to gradually decline over time due to factors like habitat loss, climate change, and resource depletion. Background extinctions typically reflect the normal turnover of species, where weaker or less adaptable organisms are outcompeted or unable to survive in changing conditions. This contrasts with mass extinctions, which are sudden and dramatic, affecting a wide range of species simultaneously.
Past mass extinctions most likely occurred as a result what?
Sudden changes in environmental conditions.
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 age of geologic time ended with the great extinction?
Well, there have been several "great extinctions" in earth's history, but the most recent one was the Cretaceous-Tertiary event, ending the Cretaceous. That was c. 65 million years ago.
What is most sweet naturally occurring sugar?
Roxas city
What is the animal group with the most extinctions?
invertabates are the animals with the most extinctions
Have extinctions occurred in the past?
Yes, extinctions have happened throughout history, they are happening today and will continue to happen in the future.
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
What has changed most of the mass extinctions on earth?
climate change

Does genocide occur in the world today?
yeah its occurring in Darfur
Where is fission occurring today?
In every nuclear reactor that is operating
Do scientists believe that extinctions are uncommon?
No, they are fundamental to the process of evolution. Mass extinctions are less common.
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.
