Which of the following accurately describes 18O/16O ratios of ice sheets?
 
  A) During warmer periods, 18O evaporates more readily and therefore the 18O/16O ratio is higher.
  B) The higher the ratio of ice core 18O/16O, the cooler there temperatures because the 18O will be locked up in ice sheets.
  C) During periods of colder temperature, the 18O/16O ratio is higher because only the 18O isotope is being evaporated.
  D) During warmer periods, 16O evaporates more readily and therefore the 18O/16O ratio is significantly lower than colder periods.
