RED OCEAN ACIDIFICATION SLIDES

Multiple Choice

What is the largest carbon sink in the world?

• The Amazon
• The Oceans
• The Deserts
• The Forests

Multiple Choice

Which statement best explainsThey remove carbon from the soil during respiration and exchange it with oxygen that evaporates into the atmosphere

• They eat plants and other organisms that contain carbon which prevents it from ever being stored.

• They eat plants and other organisms which contain carbon and deposit carbon into the soil when they die.

• They remove carbon from the atmosphere during respiration and replace it with oxygen that is used in photosynthesis.

• They remove carbon from the soil during respiration and exchange it with oxygen that evaporates into the atmosphere.

Multiple Choice

Why is the concept of a carbon sink significant in understanding Earth's carbon cycle?

• It helps explain how carbon is stored and cycled in nature

• It only refers to artificial reservoirs

• It is unrelated to climate change

• It describes how carbon is released into the atmosphere

Open Ended

How does the ocean soak up CO₂?

Multiple Choice

According to this slide

• CO₂ is causing marine life to die by "poisoning' the water

• CO₂ is destroying sea shells

• CO₂ is formed from the combustion of Octane

Multiple Choice

What is ocean acidification and how does it affect marine life?

• Ocean acidification is the process of the ocean becoming more acidic due to the absorption of carbon dioxide from the atmosphere. It can negatively affect marine life by impacting the ability of organisms such as corals, shellfish, and plankton to build and maintain their shells and skeletons.

• Ocean acidification is the process of the ocean becoming less acidic due to the absorption of carbon dioxide from the atmosphere. It has no impact on marine life.

• Ocean acidification is a natural process that has no effect on marine life.

• Ocean acidification is caused by the release of oxygen into the ocean, which can lead to increased marine life and biodiversity.

Multiple Choice

What is the primary cause of increasing ocean acidification?

• Increasing ocean carbon levels

• Ocean warming

• Increasing ocean salinity

• Pollution

Multiple Choice

Which of the following statements best explains why building new shells becomes increasingly difficult for marine organisms as ocean acidity increases?

• Higher acidity dissolves shell material, making it harder to form shells.

• Higher acidity increases the temperature of the ocean, affecting shell formation.

• Higher acidity reduces the amount of oxygen available for shell formation.

• Higher acidity increases the amount of plankton, which competes for shell material.

Multiple Choice

Which of the following liquids is considered alkaline according to the pH scale shown?

• Lemon juice

• Ocean water

• Vinegar

• Tomato juice

Open Ended

How does the absorption of carbon dioxide by the ocean affect its pH and the organisms living in it?

Multiple Choice

What is the main function of litmus paper in scientific experiments?

• To measure temperature

• To measure acidity

• To measure pressure

• To measure salinity
