What is cause background extinction?
It is the fate of most living things eventually to go extinct. standard commonplace rate of extinction not associated with a mass extinction.
When the last member of a species dies is said to have occurred.?
the answer to the question is extinction
What is the disappearance of a species from all part of an environment?
The disappearance of a species from all parts of an environment is known as extinction. This occurs when the last existing member of a species dies, leading to its complete disappearance from the planet. Extinction can be caused by various factors, including habitat destruction, climate change, pollution, and hunting.
Why do scientists think that australopithicus afarensis became extinct?
Scientists believe that Australopithecus afarensis became extinct due to a combination of factors such as changing environmental conditions, competition for resources with other species, and potential predation pressure. The inability to adapt to new ecological challenges may have also contributed to their extinction.
What do most scientists think caused the mass extinction?
Most scientists believe that the Cretaceous extinction event was caused by a 6 mile wide asteroid that impacted Earth at what is now the Yucatan Peninsula 65.5 million years ago. The impact would have thrown tremendous amounts of dust high into the atmosphere, which would have blocked the sun for months. Without sunlight, the plants would have died, and without the plants, so would any herbivorous animals. The carnivores would have then died, too. Another theory popular with scientists is that climate change was the cause of the extinction. Before the asteroid impact, a huge volcanic trap (a large lava flow) called the Deccan Traps had been erupting for about three million years. The amount of carbon dioxide it released into the atmosphere caused tremendous global climate change, and dramatically decreased the variety of dinosaur species. It is also very plausible that it was a combination of these two factors.
With what scientists proposed the meteorite impact hypothesis to explain the extinction of the?
Dinosaur?
Does an asteroid contribute to extinction?
I believe it does. Scientists think that an asteroid wiped out the dinosaurs.
Why are scientists. concerned about the depletion or thinning of the ozone layer?
Scientists are concerned about the ozone depletion. It is because this depletion can cause extinction of human race.
What do scientists consider the number one cause of extinction?
Habitat destruction is considered the number one cause of extinction by scientists. Loss of habitats due to human activities such as deforestation, urbanization, and pollution can significantly impact biodiversity and lead to the extinction of species.
Why do scientists think there are s few redwood species alive today?
Scientists believe that changes in the Earth's climate cause extinction of trees;P
How do scientists know that KT extinction took place?
When we see that there are fossils found in a certain geological layer, which are evidence that a certain species existed at that time, and then in the next geological stratum we no longer find those fossils, and there is no evidence that the species which used to exist still exists, we infer that the species became extinct. If a whole lot of species become extinct at approximately the same time, we call that an extinction event, such as the KT extinction.
How do scientists tie biblical creation in with the extinction of the dinosaurs?
Most scientists do not believe in Biblical Creation, so there is no reason to tie it with the extinction of dinosaurs. However, Creationists often say that humans originally co-existed alongside dinosaurs until the Great Flood, when dinosaurs all drowned.
How did the ambulocetus become extinct?
Bambiraptor lived in the Late Cretaceous period and i believe died out in the mass K-T extinction. this extinction would be where scientists believe that a meteor hit the Yucatan Peninsula.
How do scientists find things out?
Scientists find things out by doing experiments.
Why are scientists concerned about specis loss if extinction is a natural process?
The extinction rate is much higher than it would be without humans, therefore most animals would have not gone extinct had it not been for human intervention.
Did the breakup of Pangaea have a effect on dinosaur extinction?
No, the breakup of Pangaea occurred long before the mass extinction of dinosaurs. The main factor believed to have caused dinosaur extinction is an asteroid impact that occurred around 66 million years ago.
How scientists are addressing ozone depletion?
Ozone depletion is addressed as the formation of holes in the ozone. It causes increase in the temperature.
