How can scientists reconstruct past climate changes from caves?
A) by measuring the rates of cavern enlargement using carbon isotopes
B) by measuring isotopes of oxygen in cave formations such as stalactites
C) by measuring the amount of carbon dioxide in air exiting at cave openings
D) by examining and dating animal remains in cave deposits
E) by quantifying size and production rate of sinkholes above a cave system

Question

Quizplus · Accepted Answer

Scientists can analyze isotopes of oxygen in cave formations like stalactites to determine past climate changes. The ratio of oxygen isotopes can indicate changes in the temperature and precipitation during the time the stalactite was forming.
