Which of the following BEST reflects the impact that ocean acidification is having on shell-building creatures:

• The juvenile creatures cannot obtain the materials that they need to build their shells.

• The mature creatures' shells are dissolving at a faster rate due to the acidifyin water.

Marine organisms make their shells from calcium and

• chloride
• carbonate
• seawater

When carbon dioxide ions react with water, what molecules do cause to be release?

• Hydrogen Ions

• Carbonate Ions

As the ocean becomes more acidic, the pH of the water

• increases
• decreases

pH measures

• The mass

• The hydrogen ion concentration in a substance

• The concentration of nitrogen in a substance

• The concentration of oxygen in a solution
