The most likely scenario was the impact of a gigantic meteor in the Yucatan Peninsula, near Chicxulub, Mexico. The ensuing global climatic catastrophe may have been enough to cause the extinction of around 60% of all species that existed before the impact. A great amount of volcanism was also occurring around this time which also may have been a contributing factor.

What was the climate during the mesosoic era?
The climate during the Mesozoic Era varied over its three periods (Triassic, Jurassic, Cretaceous). Overall, it was warmer than today, with higher CO2 levels leading to greenhouse conditions. The era also experienced fluctuations in temperature, sea levels, and the development of diverse ecosystems.
What is Cretaceous Limestone?
Cretaceous limestone is a type of sedimentary rock formed during the Cretaceous period, approximately 145 to 66 million years ago. It is made up of predominantly calcium carbonate minerals derived from the remains of marine organisms such as corals, shells, and algae. Cretaceous limestone is often used as a building material and in the production of cement.
During the 20th century earth's average surface temperature has?
increased significantly due to human activities releasing greenhouse gases into the atmosphere. This has caused global warming, leading to changes in climate patterns and more frequent extreme weather events. Efforts are being made to reduce these emissions and mitigate the impacts of climate change.
What is the climate like during an ice age?
During an ice age, the climate is characterized by colder temperatures, extensive ice sheets covering large portions of the Earth, and lower sea levels due to the formation of glaciers. The climate is generally drier, with reduced precipitation and changes in weather patterns. Additionally, there can be significant fluctuations in temperature and periods of rapid climate change.
What is the climate change term for coldest phase of climate cycle?
The term for the coldest phase of a climate cycle is "glacial period" or "ice age". During a glacial period, Earth experiences lower global temperatures and an expansion of ice sheets.
What was the environment compared to the present in the cretaceous?
The climate of the Cretaceous period was warmer and more humid than it is today. The Earth's landmasses changed during the Cretaceous and sea level was higher then than it is today.
How did the climate change during Hurricane Katrina?
The climate does not change during or as a result of hurricanes.
What is a climate change that allowed flowering plants to increase?
The climate change that allowed flowering plants to increase was the gradual cooling of Earth during the Cretaceous period, which created more temperate climates. This change provided favorable conditions for the diversification and spread of flowering plants, enabling them to outcompete other plant species and dominate terrestrial ecosystems.
What was the climate during the cretaceous period?
It snowed in the high altitudes. It then warmed up because of volcanic activity everywhere. Smolls Rule!!
What event do scientist think may have caused the mass extinction at the end of the Paleozoic?
the climate change during the shifting of the plates that was causing the making of Pangea
Why did pteranodon extinct?
Pterosaurs declined during the Late Cretaceous due to competition with early birds. The last pterosaurs became extinct in the End Cretaceous Mass Extinction, which was caused by an asteroid impact in the Gulf of Mexico.
During which era did the mosasaur swim in the interior seaway?
probably during the early part of the Cretaceous Period
How did dinosaurs change during the Cretaceous period?
No. If you count birds as dinosaurs, they still exist. If you don't, dinosaurs became extinct at the end of the Cretaceous, not the beginning.
Why those days dinaursaur alive?
Dinosaurs lived during the Mesozoic Era, which spanned from approximately 252 to 66 million years ago, and is divided into three periods: Triassic, Jurassic, and Cretaceous. They thrived in a warm climate with diverse ecosystems, adapting to a variety of environments. Their extinction at the end of the Cretaceous period, likely caused by a combination of a massive asteroid impact and volcanic activity, marked the end of the age of dinosaurs.
Could Antarctica ever have a tornado?
It is highly unlikely with the current climate. However, at times, such as during the Cretaceous period, Antarctica had a much warmer climate than it does not, even supporting forests. At that time, tornadoes may have been ocurred.
What epoch did the T.Rex live in?
CRETACEOUS PERIOD144-65 Million Years Agoand in the really really really REALLY late jurassicbut mostly cretaceous
Why did the andrewsarchus go extinct?
andrewsarchus might have gone extinct during the central Asian extinction caused by the formation of the Himalaya Mountains 40 million tears ago or because of Habitat loss maybe Global warming and Climate change
