What argument that describes the cause of the cretaceousmass extinction is best supported by the evidence?
Group of answer choices
Evidence of ash and heightened CO2 levels in rock strata formedat the time of the extinction event is evidence that volcanicactivity increased global temperatures and reduced the availabilityof nutrients.
Heightened levels of oxygen in the soil shows that theenvironment was able to support large predators for the first time,wiping out many vulnerable species.
The presence of iridium, which is not common on earth, in rockstrata that correspond to that time period indicates that a massivemeteorite hit the earth.
An increase in the diversity of mammal species in the fossilrecord following the cretaceous mass extinction demonstrates thatthose species were able to outcompete the dinosaurs and drive themto extinction.
