There are a lot of reasons. One is a big cloud (like one resulting from massive volcanic activity or the impact of a large asteroid) can block the Sun and plants would not s…urvive, so then many herbivores die followed by most carnivores. When an environment changes the organisms living in it may not have the time to evolve to adapt, and so they die. A change in climate can lead to extinction because it can destroy organisms' habitats. For example, woolly mammoths had thick fur that was perfect for keeping themselves warm in the cold area. When global warming caused the climate to become warmer, their traits for cold weather were no longer helpful and eventually became extinct.
If you could pick up and weigh a single atom of magnesium the mass of that atom would most likely weigh what?
Well... one could be the same mass as 12 protons + 12 neutrons + the mass defect.
The Permian-Triassic Extinction
id say all the rain forest being burned down or CUT down. it makes me sad to see that many people dont care about all these animals....
Typically, cold-blooded animals are more likely to survive mass extinctions than their warmblooded counterparts. Animals who are lower in the food chain are also more likely t…o survive. Mass extinctions, however, vary in their causes, and so also vary in their effects.
Volcanism, asteroid bombardment, radiation from space, climate change from various causes, disease, and (future) nuclear war.
well,some animals can't survive in a climate their not used to,or not meant for it.For ex:after the Continental Drift of pangea,animals that lived in warm climates were placed… in below zero climates,which could have led to their extinction. hope this helped!
The fastest extinction of life on Earth occurred 65 million years ago when over 80% of the earth's organisms went extinct. This occurred in a relatively short 2-5 million year…s,
"It was the Cretaceous-Tertiary or the K-T Extinction." - Wrong The K-T Extinction was the mass extinction that wiped out the dinosaurs, which was more widely believed to …be caused by a heavenly body colliding with the Earth. The mass extinction that involved a large period of glaciation was in truth the Ordovician-Silurian Extinction, which was the earliest mass extinction. The extinction is associated with a period of glaciation. First, sea levels dropped as glaciers formed. Later, as the glaciers melted, the sea level rose. The cause of this glaciation remains a mystery. One suggestion is land plants caused it by absorbing large amounts of carbon dioxide from the atmosphere. The drop in carbon dioxide could then have caused global cooling.

A large enough asteroid could (theoretically) knock the Earth off of it's axis and closer or further away from the sun.
Asteroids have been known to have caused mass extinctions. The obvious one is the Cretaceous--Tertiary extinction event which wiped out the dinosaurs. Others, have also been n…oted.
Which of what? I can't answer your question if it's vague like this.
Gasses released by a massive volcanic event can cause catastrophic climate changes. Carbon dioxide will raise global temperatures. while sulfur dioxide will lower temperat…ures.
