What if true would most support the author's assertion about the Cretaceous-Tertiary extinction event that the result was a revolution lines 79-80?
If evidence showed that the Cretaceous-Tertiary extinction event led to a rapid diversification of species and the emergence of new ecological niches, this would strongly support the author's assertion that the event resulted in a revolutionary shift in life on Earth. Additionally, if studies indicated that this extinction paved the way for mammals to dominate and evolve into various forms, it would further emphasize the transformative impact of the event on the planet's biological landscape.
What ended the Jurassic period?
The end of the Silurian period and the beginning of the Devonian period was not defined by an extinction event, but by the distinctive rock formations of the period. As a result the end of the Silurian period is uncertain by +/- 2.8 million years.
When did the meteor hit earth near chicxulub mexico?
Simply - they died.There is a lot of controversy about the Chicxulub event, but the theory has stood up against time, so it seems to be the most acceptable explanation for the demise of the dinosaurs.
What happened as a result of an asteroid collision on the Yucatan peninsula 65 million years ago?
The impact of an asteroid on the Yucatan peninsula led to a mass extinction event, including the end of the dinosaurs, due to intense wildfires, tsunamis, and a "nuclear winter" effect caused by debris blocking the sun. It also created the Chicxulub crater, which is over 180 kilometers in diameter.
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.

How long ago did trex live?
Tyrannosaurus rex lived during the end of the Maastrichtian stage of the Cretaceous period. That was about 68 to 65.5 million years ago. They died out as a result of the K-T extinction event.
What era was the chicxulub crater formed?
The Chicxulub crater was formed during the Cretaceous Period, around 66 million years ago. It is believed to have been the result of a large asteroid impact, which is thought to have contributed to the mass extinction event that led to the extinction of the dinosaurs.
What made the cretaceous period end?
The Cretaceous period ended as the result of a mass extinction event, probably resulting from an asteroid impact. This wiped out 65 percent of life on earth, including the ammonites, the plesiosaurs, the pterosaurs, and, most famously, the dinosaurs.
What ended the Cretaceous Period?
The mass extinction of the dinosaurs occured at the end of the Cretaceous Period. There are many theories as to why this happened. Some say a volcanic eruption caused it or a falling meteorite.
What evidence suggests that a mass extinction of the dinosaurs occurred at the end of the cretaceous?
The Cretaceous period ended as the result of a mass extinction event, probably resulting from an asteroid impact. This wiped out 65 percent of life on earth, including the ammonites, the plesiosaurs, the pterosaurs, and, most famously, the dinosaurs.
What is the result of the death of the last member of a species?
= extinction
How mass extinction affected life on Earth?
Mass extinction isn't a natural role in any life-system. They happen as a consequence of some catatrosphic disaster or radical unbalance in the eco-system. As a result of mass extinctions other 'groups' evolve into species that take the place of those exterminated.
What period of time did ammonites live in?
Devonian to cretaceous is the the geological age of ammonoids They first appeared during the Devonian Period (approximately 410 million years ago). They almost died out at the end of the Permian Period (251 million years ago), and again at the end of the Triassic Period (205 million years ago). They finally became extinct at the end of the Cretaceous Period (65 million years ago), perhaps as a result of a lowering of ocean levels.
Extinction is the result of a failure to do what?
a failure to continue living
Widespread hunting predators may result in what?
It may result to the extinction of our wildlife animals.
What is the result to a change in the environment?
global warming>>>drought, extinction
