Kelp Test 2: Reteaching Assignment: Carbon Dioxide and pH

During a science class experiment, Benjamin observed the effect of increasing carbon dioxide (CO2) levels on ocean water. What happens to the pH level of ocean water as the concentration of carbon dioxide (CO2) increases?

• The pH level increases, making the water more alkaline.

• The pH level decreases, making the water more acidic.

• The pH level does not change.

• The pH level fluctuates unpredictably.

During a science class, Nora and Grace were discussing environmental issues. Which of the following best describes ocean acidification?

• The process by which oceans become more alkaline due to decreased CO2 levels.

• The process by which oceans become more acidic due to increased CO2 levels.

• The addition of acid to ocean waters by pollution.

• The natural fluctuation of ocean pH levels.

Scarlett and Hannah are studying the impact of ocean acidification on marine life. They observe that the shells of marine organisms such as snails and clams are affected. How does ocean acidification affect these shells?

• Makes their shells stronger and thicker.

• Has no effect on their shells.

• Makes their shells weaker and thinner.

• Changes the color of their shells.

Emma and Charlotte are studying the effects of increased carbon dioxide levels on marine environments. They learn about a phenomenon that causes a decrease in the pH of the Earth's oceans due to the uptake of carbon dioxide from the atmosphere. What is this phenomenon called?

• Global warming

• Ocean acidification

• Ocean deoxygenation

• Marine pollution

• Sea turtles

• Coral reefs

• Sharks

• Calcification

• Carbonation

• Acidification

Abigail and Mason are working on a project to reduce carbon dioxide levels in the atmosphere. They learn that removing carbon dioxide from the atmosphere will ultimately cause less carbon dioxide to diffuse into the ocean. This will result in:

• the pH of the ocean to decrease and become more acidic.

• the pH of the ocean to decrease and become more basic.

• the pH of the ocean to increase and become more acidic.

• the pH of the ocean to increase and become more basic.

Maya is studying the effects of ocean acidification on marine life. What can be the long-term effect of ocean acidification on the global food chain?

• Increased biodiversity in the oceans.

• Decreased biodiversity in the oceans.

• More stable fish populations.

• No significant change.
