6. How does climate change affect ocean acidity?

Correct Answer: Correct answer is: (B) It increases ocean acidity.

Exam Relevance: AP Environmental Science, MCAT, GRE Biology

Difficulty: Moderate

Concept notes: Climate change leads to increased levels of carbon dioxide (CO₂) in the atmosphere, which is absorbed by the oceans. This absorption causes a chemical reaction that increases the acidity of seawater.

Common Mistakes: A common misunderstanding is that climate change only affects temperature and weather patterns, without recognizing its impact on ocean chemistry.

Explanations: As atmospheric CO₂ levels rise due to climate change, more CO₂ is absorbed by the oceans. This leads to the formation of carbonic acid (H₂CO₃), which dissociates into hydrogen ions (H⁺) and bicarbonate ions (HCO₃⁻). The increase in hydrogen ions directly increases the acidity of the ocean, measured by a decrease in pH.

Option Analysis:

Option A: This is incorrect because climate change does not stabilize ocean acidity; it actually increases it.
Option B: This is correct because the absorption of CO₂ by the oceans leads to increased acidity.
Option C: This is incorrect because climate change does have an effect on ocean acidity, specifically by increasing it.
Option D: This is incorrect because climate change does not decrease ocean acidity; it increases it.

Correct Answer: Correct answer is: (D) Excessive heat promotes plant flowering.

Exam Relevance: AP Environmental Science, GRE Subject Test in Biology, MCAT

Difficulty: Moderate

Concept notes: Climate change impacts agriculture through various mechanisms, including increased CO2 levels, temperature changes, and altered precipitation patterns. However, excessive heat does not typically promote plant flowering; instead, it can have detrimental effects on plant growth and crop yields.

Common Mistakes: A common misunderstanding is that higher temperatures always benefit plant growth and flowering. In reality, excessive heat can stress plants and reduce their ability to flower and produce viable crops.

Explanations: Excessive heat can negatively impact plant growth and flowering. High temperatures can cause heat stress, which can lead to reduced photosynthesis, wilting, and even plant death. This is contrary to the idea that excessive heat promotes plant flowering. In contrast, increased CO2 levels can act as a fertilizer, but they can also reduce the nutrient content of crops. Increased temperatures and drought can lead to the loss of arable land, and flooding can remove topsoil and drown crops.

Option Analysis:

Option A: Increased CO2 levels can act as a fertilizer, but they can also reduce the nutrient content of crops, which is a valid impact of climate change on agriculture.
Option B: Increased temperatures and drought can lead to the loss of arable land, which is a valid impact of climate change on agriculture.
Option C: Flooding can remove topsoil and drown crops, which is a valid impact of climate change on agriculture.
Option D: Excessive heat does not promote plant flowering; instead, it can have detrimental effects on plant growth and crop yields, making this the correct answer as it is not a valid impact of climate change on agriculture.
