atmosphere
land biomass
rocks
Question 7 (2 points)
Which carbon reservoir changes the quickest and has the biggest direct effect on climate?
Question 7 options:
land biomass
ocean
atmosphere
rocks
Question 8 (2 points)
Which best describes the process of ocean acidification?
Question 8 options:
The ocean absorbs more human-produced CO2, causing the acidity to increase
The ocean releases more human-produced CO2, causing the acidity to decrease
The ocean absorbs more natural CO2, causing the acidity to decrease
The ocean receives more polluted runoff, causing the acidity to increase
Question 9 (2 points)
What is a potential impact of ocean acidification?
Question 9 options:
Animals will have a harder time building their shells
Corals may have a harder time building their skeletons
Ocean ecosystems may suffer, making it harder for humans to get food from the ocean
All of the above

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.
