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.
sunlight
Yes it can
poaching.
What_may_cause_a_lion_extinction
Yes.
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.
