How do we know that climate change killed the dinosaurs?
Climate change is among the theories proposed to explain the extinction of the dinosaurs. Evidence includes fluctuations in global temperatures, changes in ocean chemistry, and the release of greenhouse gases. Fossil records also show a rapid decline in biodiversity around the time of the dinosaur extinction event.
Why could climate change have killed the dinosaurs?
One hypothesis is that climate change from a massive asteroid impact led to a decrease in temperature and sunlight, disrupting the food chain and causing widespread extinction among plant and animal species, including the dinosaurs. This sudden change may have been too drastic for the dinosaurs to adapt to, leading to their eventual extinction.
Who really killed the dinosaur?
It is not a "who" but a what that killed off the dinosaurs. It is thought that an asteroid hit the earth causing a prolonged winter which killed off all the plants so they starved to death and died.
What ended the Jurassic time period?
The end of the Jurassic period was marked by a mass extinction event that wiped out a significant portion of species, including some dinosaurs. This event was likely caused by a combination of volcanic activity, climate change, and possibly an asteroid impact.
Is there a link between extinction and climate change?
Yes, there is a strong link between extinction and climate change. Climate change can disrupt ecosystems and alter habitats, putting many species at risk of extinction. Changes in temperature, precipitation patterns, and sea levels can directly affect an organism's ability to survive and reproduce, leading to population declines and potential extinctions.

3 possible contribution of extinction of the dinosaurs between the creatceous and tertiary?
Impact event: The most widely accepted theory is that a large asteroid impact caused drastic environmental changes leading to the extinction of the dinosaurs. Climate change: Volcanic activity and changes in atmospheric composition could have led to significant climate disruption, affecting the food chain and ultimately leading to the extinction of the dinosaurs. Competition and evolution: The rise of new species, particularly mammals, may have outcompeted dinosaurs for resources, leading to their decline and eventual extinction in the Cretaceous-Tertiary boundary.
What is the most likely reason for the extinction of all the dinosaurs?
most probably change in the climatic condition was the main reason for their extinction!!
Is there a Mass extinction in the Jurassic period?
There was a minor extinction event at the end of the Jurassic period. It was probably caused by global climate change. Dinosaurs like Allosaurus, Ceratosaurus, Camarasaurus, and Stegosaurus couldn't adapt to the change in temperature, so they all died out. The Cretaceous period then came after the Jurassic period had ended.
What were the challenges the dinosaurs faced before they were EXTINCT?
The dinosaurs were going through dramatic climate change.
Animals of the mesozoic extinction?
During the Mesozoic extinction, some of the animals that went extinct included non-avian dinosaurs, pterosaurs, marine reptiles like ichthyosaurs and mosasaurs, and various marine invertebrates. This extinction event was primarily caused by a combination of volcanic activity, climate change, and possibly asteroid impact, leading to the demise of many species that could not adapt to the changing environment.

Why is the extinction of the dinosaurs attributed to an asteroid impact?
The original observation was that in the fossil records there is a layer with high levels of iridium and osmium at the time of dinosaur extinction. Iridium and osmium are common is asteroids. For the layer to be all over the globe it must have been a major strike which would have caused global wide climate change causing a mass extinction.
Is there a link between extinction and climate change?
Yes, there is a strong link between extinction and climate change. Climate change can disrupt ecosystems and alter habitats, putting many species at risk of extinction. Changes in temperature, precipitation patterns, and sea levels can directly affect an organism's ability to survive and reproduce, leading to population declines and potential extinctions.
What evidence states dinosaurs became extinct from a volcanic eruption?
None. The extinction of the dinosaurs was created by a meteor crashing into Earth. The initial impact was in the nowaday's Gulf of Mexico and did evough damage. On top of that, the debris blocked out the sun and created a severe climate change. Hypercanes were huge storms that needed that heat to be created. All of this killed of the dinosaurs.
