Correct Answer: Correct answer is: (D) The burning of fossil fuels is increasing the level of carbon dioxide in the atmosphere.

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

Difficulty: Moderate

Concept notes: The greenhouse effect is a natural process that warms the Earth's surface. Certain gases in the atmosphere, known as greenhouse gases, trap heat from the sun. The primary greenhouse gas is carbon dioxide (CO2), which is released into the atmosphere through human activities such as burning fossil fuels.

Common Mistakes: A common misunderstanding is that natural processes like volcanic activity or changes in the Earth's axis are the main causes of global warming. However, the significant increase in CO2 levels due to human activities is the primary driver of the enhanced greenhouse effect.

Explanations: The burning of fossil fuels, such as coal, oil, and natural gas, releases large amounts of CO2 into the atmosphere. This increase in CO2 enhances the greenhouse effect, leading to a faster warming of the Earth's surface. The other options do not directly contribute to the enhanced greenhouse effect in the same significant manner.

Option Analysis:

Option A: Rising sea levels do not directly cause more solar energy to be absorbed by the oceans. Instead, warmer temperatures due to increased CO2 levels can lead to rising sea levels.
Option B: The Earth's axis tilt does not significantly change over short periods and does not contribute to the enhanced greenhouse effect.
Option C: Increased volcanic activity can release dust and gases into the atmosphere, but the primary greenhouse gas, CO2, is more significantly increased by human activities.
Option D: The burning of fossil fuels increases CO2 levels, which enhances the greenhouse effect and leads to faster warming of the Earth.
