Can a tsunami cause extinction of a species?
Yes. If a certain area has a group of animals living in a compact space, that species could become extinct easily. Also, a tsunami could cover a large area, harming species and the food chain which could later lead to extinction.
How does global warming affect extinction?
Global warming changes natural habitats making them unliveable for many species ==== Global warming was the first effect identified that was shown to lead to species extinction events. For instance, a mountain frog would migrate from lower to higher elevations annually to survive. The species is now extinct because of global climate instability. The frog reached the top of the mountain and it was still too warm and their species died, all of them; extinct. There is a difference between Mass Extinction and Global Extinction. Mass Extinction is where a large percentage of a species dies. -- This is like a plague that wipes out 90% of a species Global Extinction is where the entire population of a species becomes extinct. -- This is like the mountain frog, it is completely extinct -- Melting of the Methane Permafrost could release enough methane to kill all humans Total Extinction is where all species globally become extinct; including ourselves. -- A large asteroid, black hole on a trajectory with our solar system, a near region super-nova, super-volcano eruption, abnormally large Solar Mass Ejection, ...
What could cause extinction of a species after a major environmental change?
Their bodies aren't adapted to the new environment yet.
Discuss the potential disastrous phenomena of global warming and ozone layer depletion?
They both are disastrous. They could cause mass extinction.
What could contribute to the extinction of a species?
MAN!
What could be an introduction for my speech on global warming?
A:Global warming is a very big issue in the world today. Global warming is when the earth's temperature rises. The cause of global warming is when greenhouse gases trap heat and light from the sun [in the atmosphere of the earth] causing the earth to heat up. Global warming affects animals and our environment, such as rise in sea levels which will cause extinction for more than a thousand species.
A lack of diversity in a population could possibly cause what?
It could cause extinction !!
What are 2 things that could cause the extinction of the cheetah?
cheetah's aren't extinct...... but like poachers and stuff could eventually lead to their extinction.
Can fish cause a mass extinction?
Yes I believe that fish could possibly cause mass extinctions. The rise of any species or family of animals or plants can cause mass extinctions. Grass had this effect when it flourished after the end of the Cretaceous Period. One particular species of hairless ape rose up from humble starts in Africa to become rulers of the the planet and cause the extinction of a great many species. All the fish would need is some change in environment that meant they could multiply numbers enough to have an effect or maybe evolve to have such advantage that they can come to dominate their environment. If there was a sudden rise in numbers with an algae eating fish such the bi-colour blenny then theoretically they could strip the oceans free of algae which remove large amounts of Carbon Dioxide from the atmosphere each year. This could cause global problems not just for marine life but also land based life as well. Fishes causing extinctions has precedents in history. The rise of the placoderms (armored fish) in the Devonian Period possibly caused the extinction of many species of marine arthropods. The went on to dominate the oceans for millions of years.
What animals are now extinct from Global Warming?
The first mammal believed extinct directly due to global warming is the White Possum. This animal was native to Australia and has not been seen for three years; an expedition is planned for 2009 to see if one can be located. Its extinction has been attributed to an extended heat wave, bringing ambient temperatures higher than the species could tolerate for such a period of time. It is difficult to attribute an extinction specifically to global warming as the problem is usually concurrent with other factors that may damage or destroy a species, including deforestation, pollution, poaching, out-competition by invasive species, or even natural causes like disease and excessive predation. Also complicating the matter is that global warming alters the environment slowly, and the environment reacts to it slowly. The destruction of one species or environment may ripple through related ecosystems over the course of years, even decades. Furthermore, the greatest threat of global warming is in the future, particularly if humans take no action to reduce or eliminate its projected damage. A great many species are threatened by the changes global warming will cause and by some projections, we could lose as much as 10% of all species on the planet by 2050, and 30% of all bird species by 2100. Some even believe global warming could eventually drive all species on earth extinct, including humans, though this is generally regarded as alarmist at worst and unhelpful at best.
What often occurs after a catastrophic global event?
Mass extinction. A mass extinction typically occurs after a catastrophic global event. This event could be a bolide impact (such as the impact 65 million years ago that killed the dinosaurs, the most famous example of a mass extinction), increased volcanism, climate change, or something similar.
What is an endangered speices?
the definition of endangered species is species who are close to extinction, or dying out; in the risk of extinction this is my personal definitionWhen an animals numbers become too low to sustain a viable population, it becomes an endangered species.
