Which of the following statements about the late Precambrian Snowball Earth is false? O Though only minor evidence exists, there must have been a mass extinction of microbes and simple eukaryotes coincident with Snowball Earth. For any life to survive the global glaciation it might have taken refuge near hydrothermal vents on the deep seafloor. O With photosynthetic organisms suppressed, volcanic gases built up in the atmosphere, enhancing the natural greenhouse effect that warmed the planet and melted the ice. A supercontinent extended from pole to pole, with thick ice sheets accumulating in the high polar latitudes then extending toward lower latitudes. O As glacial ice grew even more widespread, it reflected sunlight back to space, enhancing the global cooling and the further expansion of glacial ice.
