During glacial periods, the concentration of carbon dioxide in trapped air bubbles in glacial ice is ___ when compared to the concentration during interglacial periods.

Question

Quizplus · Accepted Answer

During glacial periods, there is less vegetation and therefore less photosynthesis occurring, which leads to a decrease in the amount of carbon dioxide being absorbed from the atmosphere. Additionally, cooler temperatures cause the ocean to absorb more carbon dioxide, further reducing the concentration in the atmosphere. As a result, the concentration of carbon dioxide in trapped air bubbles in glacial ice is lower when compared to interglacial periods when the opposite conditions occur.
