During the end-Cretaceous extinction event, most of the dinosaurs, the dominant vertebrate group for millions of years, disappeared. Which of the following causes are hypothesized to have contributed to this mass extinction? asteroid impact volcanic eruptions ocean acidification all of these answers are correct climate change

Please answer these questions: 1) During the Cretaceous period, 100 MY ago, super-eruptions of volcanoes produced what rare mineral in kimberlite deposits? 2) How long ago did a mass extinction kill the dinosaurs and many other animals? What is the evidence for this event? What is Chicxulub?

The history of life has been punctuated by several mass extinctions. For example, the impact of a meteorite may have wiped out most of the dinosaurs and many forms of marine life at the end of the Cretaceous period (see Chapter 25). Fossils indicate that plants were less severely affected by this mass extinction. What adaptations may have enabled plants to withstand this disaster better than animals?
