Two probable causes of mass extinctions are volcanic activity and asteroid impacts. Massive volcanic eruptions can release large amounts of ash and gases, leading to climate changes and disrupting ecosystems. Similarly, asteroid impacts can cause immediate destruction and trigger long-term environmental shifts, such as blocking sunlight and altering temperatures, resulting in the collapse of food chains. Both phenomena have been linked to significant biodiversity loss in Earth's history.
What else can I help you with?
What is a probable cause of two mass extictions?
For all mass extinctions (except the Cretaceous/Paleogene extinction) two probable causes are volcanic eruptions and ocean anoxia.
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
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 are two natural factors caused by nature that can cause extinctions?
climate change and asteroid impact
What two particles are approximately equal in mass?
You think probable to proton and neutron.
How many extinctions has earth experienced in its history?
Mass extinctions--at least two--one at the end of the Permian, and one at the end of the Cretaceous, with numerous other less severe events. As far as the extinction of individual species, that list would cover millions of extinct organisms.
How is probable cause and reasonable suspicion similar?
Probable cause and reasonable suspicion are legal actions that can be enforced by a law officer. These two actions are similar in that they give the police officer the ability to gain access when investigating a criminal action.
If two people are parked in a car can police ask them to exit it then search car?
I think they only can search the car if they have probable cause.

What two actions should the technician take if the testing did not identify an exact cause?
Establish a new theory of probable causes. document correct the problem.
What was the case that established a two pronged test to the effect what informant info could be establish probable cause if both criteria were met is?
Aguilar v. Texas
