What are two catastrophic events that can cause mass extinctions?
An asteroid from space, and Gradualevents
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 two things does a stars absolute magnitude depend?
Mass and age.
What causes rainfall fluctuations?
There are several things that cause rainfall fluctuations. Two things that will cause rainfall to vary is the location and temperature.
What are the two most common things moved by mass transit?
People and goods

For all mass extinctions (except the Cretaceous/Paleogene extinction) two probable causes are volcanic eruptions and ocean anoxia.
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 is an probable cause of two Mass extinctions?
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 are two things that has mass?
Two things that have mass are an apple and a rock.
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.
What does mass determine?
Mass determines two things: gravitational attraction, and inertia.
What two things can cause the gravitational force between objects to?
The gravitational force between objects can be caused by their mass and the distance between them. The greater the mass of the objects and the shorter the distance between them, the stronger the gravitational force will be.
What two things can cause a population to decrease?
A low birth rate and environmental hazards are two things that can cause a population to decrease.
