QUESTION 6Several previous mass extinctions during the history of the earth were the result of either global warming or cooling. What was the major factor that caused globaltemperatures to change so dramatically hundreds of millions of years ago?O A Changing atmospheric carbon dioxide concentrationO B. The phases of the moonOC. The burning of fossil fuels by humansOD.Changes in the length of the dayQUESTION 7The increase in the Earth's temperature during the Paleocene Thermal Maximum (PETM) and our current human-driven global warming were/are both beingdriven by increasing atmospheric carbon dioxide concentration. However, what is a major difference between these occurrences of global warming?O A. One was caused by the Greenhouse Effect while the other wasn't.O B. Plate tectonicsOC. Global temperature is rising much more quickly today than it did during the PETMOD. The earth stopping spinning on its axis during the PETM

It is due to the phases of the moon i.e. option B is correct.
