Oxygen-isotope analysis:
A)has been shown to be of little or no use in the study of past climatic changes.
B)makes use of the fact that as temperatures decreases,the amount of ¹⁸O found in precipitation increases.
C)relies on the fact that ¹⁶O evaporates from the ocean more readily than ¹⁸O.
D)is very simple.

Question

Quizplus · Accepted Answer

Oxygen-isotope analysis is based on the principle that lighter isotopes, like ¹⁶O, evaporate more easily than heavier isotopes, like ¹⁸O. This difference is used to study past climates by examining the ratio of these isotopes in ice cores and ocean sediments.
