The hydrosphere accounts in large part for the fact that our atmosphere is thinner thanVenus's and contains far less carbon dioxide.

Question

Quizplus · Accepted Answer

The hydrosphere plays a key role in regulating the composition of the Earth's atmosphere, including its thickness and the levels of carbon dioxide present. Venus, by contrast, has a much thicker atmosphere and a runaway greenhouse effect due in part to the lack of liquid water. The hydrosphere, which includes bodies of water and the water cycle, helps regulate Earth's atmospheric composition by removing carbon dioxide through processes like photosynthesis and chemical weathering. This is one reason why our atmosphere is thinner than Venus's and contains less carbon dioxide.
