5. What factors caused an increase in global forest cover as the present inter-glacial period began?

Correct Answer: Correct answer is: (C) Warmer conditions, more precipitation, glaciers retreating.

Exam Relevance: AP Environmental Science, GRE, MCAT

Difficulty: Moderate

Concept notes: During the present inter-glacial period, warmer conditions and increased precipitation led to an expansion of forest cover. As glaciers retreated, they exposed new land for vegetation to grow.

Common Mistakes: A common misunderstanding is that colder conditions and expanding glaciers would lead to increased forest cover. However, colder conditions and expanding glaciers typically result in reduced vegetation and forest cover.

Explanations: Warmer conditions and increased precipitation create favorable environments for plant growth. As glaciers retreat, they uncover new land that can be colonized by vegetation, leading to an increase in forest cover. This is consistent with the observed patterns during the present inter-glacial period.

Option Analysis:

Option A: Warmer conditions and more precipitation are correct, but expanding glaciers would not lead to increased forest cover.
Option B: Colder conditions and retreating glaciers are not consistent with increased forest cover.
Option C: Warmer conditions, more precipitation, and retreating glaciers are all factors that contribute to increased forest cover.
Option D: Warmer conditions and expanding glaciers are contradictory, and less precipitation would not support increased forest cover.

Mnemonic: Warm, Wet, Glaciers Gone

6. What affect does adding more CO2 into the atmosphere have on the oceans?

Correct Answer: Correct answer is: (A) It makes them more acidic.

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

Difficulty: Moderate

Concept notes: When carbon dioxide (CO2) is added to the atmosphere, it dissolves in seawater and forms carbonic acid, which increases the acidity of the oceans.

Common Mistakes: A common misunderstanding is that CO2 in the atmosphere directly affects the temperature of the oceans, rather than their acidity.

Explanations: Carbon dioxide (CO2) in the atmosphere dissolves in seawater and undergoes a chemical reaction to form carbonic acid (H2CO3). This reaction increases the concentration of hydrogen ions (H+) in the water, thereby lowering the pH and making the oceans more acidic. This process is known as ocean acidification and is a significant consequence of increased atmospheric CO2 levels due to climate change.

Option Analysis:

Option A: Correct. CO2 dissolves in seawater to form carbonic acid, increasing the acidity of the oceans.
Option B: Incorrect. CO2 does not make the oceans more basic or alkaline; it makes them more acidic.
Option C: Incorrect. CO2 does not directly make the oceans colder; it affects their acidity.
Option D: Incorrect. CO2 does not make the oceans wetter; it affects their acidity.

Mnemonic: CO2 + H2O = Acidic Oceans
