Question 6 1 pts Why does the ratio of 16.0" change in the shells found in deep sea sediment cores? During cool periods, more water containing O16 is stored as ice on land, reducing old in the sea During warm periods, more of from decaying land plants is flushed out to the ocean by rivers The shells of organisms with in them are dissolved more easily in cool water than in warm water. During cool periods, organisms use more of to construct their shells than during warm periods. During warm periods more evaporation of seawater containing 01 occurs, removing o1 from the sea.
