Which of the following contributed to the terrestrial mass extinctions during the end-Permian extinction? A) global warming caused by CO₂ emissions from volcanic activity B) toxic metal poisoning caused by toxic metal emissions from lava flow C) increased UV-B radiation from ozone depletion by Cl, F, and NOx emissions D) acid rain caused by Cl, F, NOx, and SO2 emissions E) all of the above

Question

Quizplus · Accepted Answer

The end-Permian extinction, also known as the Great Dying, was caused by a combination of factors including global warming from volcanic CO2 emissions, toxic metal poisoning from lava flows, increased UV-B radiation due to ozone depletion by various emissions, and acid rain from emissions of chlorine, fluorine, nitrogen oxides, and sulfur dioxide. These factors created a hostile environment leading to the most severe extinction event in Earth's history.
