AP Environmental Science Exam

Question 1

The Green Revolution of the mid-20th century primarily involved:

A global shift from meat-based to plant-based diets Development of high-yielding crop varieties, increased irrigation, and synthetic fertilizer use that dramatically raised food production International agreements to protect tropical rainforests from agricultural expansion Organic farming methods that eliminated the need for pesticides

Correct Answer:

Development of high-yielding crop varieties, increased irrigation, and synthetic fertilizer use that dramatically raised food production

Question 2

Monoculture farming poses environmental risks primarily because:

It requires more land than polyculture for the same yield Genetic uniformity increases vulnerability to pests, diseases, and climate variability Monocultures cannot be harvested by mechanized equipment Single crops deplete soil carbon faster than no-till methods

Correct Answer:

Genetic uniformity increases vulnerability to pests, diseases, and climate variability

Question 3

Contour plowing reduces soil erosion by:

Plowing in the same direction as slope to channel runoff quickly off the field Plowing across (perpendicular to) the slope so furrows act as barriers that slow water flow Deep plowing that buries topsoil below the erosion-prone surface layer Using mechanized equipment to minimize soil disturbance during planting

Correct Answer:

Plowing across (perpendicular to) the slope so furrows act as barriers that slow water flow

Question 4

The primary cause of hypoxic dead zones in coastal marine ecosystems is:

Thermal pollution from power plant cooling water Nutrient runoff (nitrogen and phosphorus) from agriculture that causes algal blooms and oxygen depletion Plastic debris that blocks sunlight and prevents photosynthesis Overfishing that removes organisms that would otherwise oxygenate the water

Correct Answer:

Nutrient runoff (nitrogen and phosphorus) from agriculture that causes algal blooms and oxygen depletion

Question 5

Integrated Pest Management (IPM) is defined as an approach that:

Eliminates all pesticide use in favor of biological control agents exclusively Combines biological, cultural, physical, and chemical controls to manage pests with minimal environmental impact Relies on genetically modified crops that are resistant to all common pests Applies pesticides on a fixed calendar schedule regardless of actual pest populations

Correct Answer:

Combines biological, cultural, physical, and chemical controls to manage pests with minimal environmental impact
