How do scientists believe that a great flood killed the dinosaurs?
Scientists do not believe that the extinction of the dinosaurs was the result of a great flood. There are still a number of competing theories about the extinction of the dinosaurs although it is clear that there was a large meteor impact in the Yucatan region, which played a role. It may also be that rising carbon dioxide levels and ocean acidity played a role as well. It may be that there were a number of contributing factors, rather than just one single cause. But scientists do not think that flooding was involved. Note that some dinosaurs were aquatic, and would not have been killed by flooding since they already lived in the water.
What would cause allele frequencies to remain unchanged?
Only one thing: extinction.
What is one gradual change that can cause a mass extinction?
One gradual change that can cause a mass extinction is climate change. If the Earth's temperature rises or falls significantly over time, it can disrupt ecosystems and lead to the extinction of many species that are unable to adapt quickly enough to the new conditions. This can result in a cascading effect on other species within the ecosystem, ultimately leading to a mass extinction event.
What is one type of catastrophic change that can cause a mass extinction?
One type of catastrophic change that can cause a mass extinction is an asteroid impact. When a large asteroid collides with the Earth, it can release massive amounts of energy, cause widespread destruction, trigger tsunamis and wildfires, and create a global "impact winter" due to the release of dust and debris into the atmosphere. Such an event is believed to have caused the extinction of the dinosaurs 65 million years ago.
What was the mass extinction in the mesozoic era caused by?
The mass extinction in the Mesozoic era, known as the Cretaceous-Paleogene extinction event, was likely caused by a combination of factors, with the impact of a large asteroid or comet in present-day Mexico being a significant factor. This impact led to widespread environmental changes, including wildfires, tsunamis, and prolonged darkness due to debris in the atmosphere, which disrupted ecosystems and caused the extinction of many plant and animal species, including 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.
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
Can hunting cause extinction?
Yes, hunting can cause extinction. Hunting destroys the animals life.
What may cause elephant extinction?
Human activity and pollution will probably be the greatest cause of elephant extinction.

What are the effects of volcanicity?
volcanic eruptions may cause mass extinctions or volcanic haze.a mass extinction is when a large number of species die out over a short period of geologic time and volcanic haze is when the gases of an eruption cause a haze and block out sunshine, causing a mass extinction.
A lack of diversity in a population could possibly cause what?
It could cause extinction !!
