1. T/F: Movement of tectonic plates and particulates in the atmosphere are natural causes of climate change.

Correct Answer: Correct answer is: (A) TRUE.

Exam Relevance: AP Environmental Science, SAT Subject Test in Environmental Science, GRE Subject Test in Geology

Difficulty: Easy

Concept notes: Climate change can be caused by both natural and human factors. Natural causes include the movement of tectonic plates and the presence of particulates in the atmosphere.

Common Mistakes: A common misunderstanding is that climate change is solely caused by human activities, such as the burning of fossil fuels and deforestation.

Explanations: The movement of tectonic plates can lead to volcanic eruptions, which release large amounts of particulates and gases into the atmosphere. These particulates can reflect sunlight, leading to a cooling effect, while gases like carbon dioxide can contribute to warming. Particulates in the atmosphere, such as dust and volcanic ash, can also affect the Earth's temperature by altering the amount of sunlight that reaches the surface. Therefore, both factors are natural causes of climate change.

Option Analysis:

Option A: Correct. The statement is true because the movement of tectonic plates and particulates in the atmosphere are indeed natural causes of climate change.
Option B: Incorrect. This option would imply that the statement is false, which contradicts the known natural causes of climate change.

2. Most of the warming that has been observed over the 20th century can be attributed to

Correct Answer: Correct answer is: (A) Human activity.

Exam Relevance: AP Environmental Science, GRE Subject Test in Environmental Science, IPCC Assessments

Difficulty: Moderate

Concept notes: The warming observed over the 20th century is primarily attributed to human activities, particularly the emission of greenhouse gases such as carbon dioxide and methane.

Common Mistakes: A common misunderstanding is that natural processes like plant growth, glacial melting, or droughts are the primary causes of climate change, when in fact, human activities have a more significant impact.

Explanations: Human activities, such as the burning of fossil fuels, deforestation, and industrial processes, have led to an increase in greenhouse gases in the atmosphere. These gases trap heat and contribute to the warming of the Earth's surface. The Intergovernmental Panel on Climate Change (IPCC) has concluded that the majority of the observed warming since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations.

Option Analysis:

Option A: Correct. Human activities, such as burning fossil fuels and deforestation, have significantly contributed to the increase in greenhouse gases, leading to global warming.
Option B: Incorrect. Plant growth can absorb carbon dioxide, but it does not contribute to the warming observed over the 20th century.
Option C: Incorrect. Glacial melting is a result of climate change, not a cause of it.
Option D: Incorrect. Droughts are a consequence of climate change, not a cause of it.

3. What are shrinking as a result of the increased global temperature?

Explanations: Global climate change is causing temperatures to rise, leading to the melting of permafrost in Alaska. Permafrost is a layer of soil that remains frozen year-round. As it melts, the ground becomes less stable, which can lead to issues such as sinkholes, landslides, and damage to infrastructure.

Option Analysis:

Option A: This is the correct answer as permafrost melting directly impacts ground stability.
Option B: While flooding can occur due to climate change, it is not the primary impact on Alaska's ground stability.
Option C: Igloos are not a common form of housing in Alaska, and melting homes is not a primary concern.
Option D: This option is incorrect as not all of the previous options are valid impacts of climate change on Alaska.

Mnemonic: Permafrost Melts, Ground Unstable (PMGU)

6. Reversal of the ordinary climate regime producing increased rain in some areas but increased drought in others

Correct Answer: Correct answer is: (B) El Nino Southern Oscillation.

Exam Relevance: AP Environmental Science, GRE Subject Test in Geosciences, GATE Environmental Science

Difficulty: Moderate

Concept notes: El Nino Southern Oscillation (ENSO) is a climate pattern characterized by the reversal of the ordinary climate regime, leading to increased rainfall in some areas and increased drought in others.

Common Mistakes: A common misunderstanding is that the Coriolis effect or prevailing winds are responsible for the reversal of climate patterns, but these phenomena do not cause the specific changes in rainfall and drought patterns associated with ENSO.

Explanations: El Nino Southern Oscillation (ENSO) is a climate pattern that involves the warming of the eastern Pacific Ocean, which disrupts the normal climate patterns. This warming can lead to increased rainfall in some regions and drought in others. The Coriolis effect and prevailing winds do not cause these specific changes in rainfall and drought patterns. Weather fronts and prevailing winds are more related to short-term weather changes rather than the long-term climate shifts associated with ENSO.

Option Analysis:

Option A: The Coriolis effect influences wind and ocean currents but does not cause the specific climate changes associated with ENSO.
Option B: El Nino Southern Oscillation is the correct answer as it is known to cause the reversal of ordinary climate regimes, leading to increased rainfall in some areas and increased drought in others.
Option C: Prevailing winds are consistent patterns of wind direction and do not cause the specific climate changes associated with ENSO.
Option D: Weather fronts are boundaries between different air masses and are associated with short-term weather changes, not the long-term climate shifts of ENSO.

Mnemonic: ENSO: El Nino Southern Oscillation, "El Nino Shifts Climate"
