9. Which of the below is NOT a natural environment

Correct Answer: Correct answer is: (C) City.

Exam Relevance: AP Environmental Science, Geography Exams, Urban Planning Exams

Difficulty: Easy

Concept notes: Natural environments are those that exist without significant human intervention. Examples include forests, deserts, and jungles. Urban environments, such as cities, are created and maintained by human activities.

Common Mistakes: A common mistake is to consider cities as natural environments because they are part of the Earth's surface. However, cities are constructed and managed by humans, distinguishing them from natural environments.

Explanations: Forests, deserts, and jungles are natural environments because they exist without significant human intervention. Cities, on the other hand, are artificial environments created and maintained by human activities, such as construction, infrastructure development, and urban planning. Therefore, a city is not a natural environment.

Option Analysis:

Option A: Forests are natural environments because they are ecosystems that develop without significant human intervention.
Option B: Deserts are natural environments because they are arid regions that form due to natural climatic conditions.
Option C: Cities are not natural environments because they are constructed and maintained by human activities.
Option D: Jungles are natural environments because they are dense forests that develop without significant human intervention.

10. Flash flooding often occurs in city areas because

Correct Answer: Correct answer is: (C) Roads, pavements and buildings reduce the infiltration of water into the ground.

Exam Relevance: AP Environmental Science, Geography exams, Urban Planning exams

Difficulty: Moderate

Concept notes: Urban areas are characterized by a high density of impervious surfaces such as roads, pavements, and buildings. These surfaces prevent water from infiltrating into the ground, leading to increased surface runoff and flash flooding.

Common Mistakes: A common misunderstanding is that urban areas have better drainage systems that can handle heavy rainfall, but this does not account for the reduced infiltration due to impervious surfaces.

Explanations: In urban areas, the presence of roads, pavements, and buildings significantly reduces the amount of water that can infiltrate into the ground. This reduction in infiltration leads to a higher volume of surface runoff, which can overwhelm drainage systems and result in flash flooding. The other options do not accurately describe the primary cause of flash flooding in urban areas.

Option Analysis:

Option A: Runoff does not decrease during precipitation; it increases due to the impervious surfaces in urban areas.
Option B: Groundwater storage is not typically large in urban areas due to the presence of impervious surfaces.
Option C: Roads, pavements, and buildings reduce the infiltration of water into the ground, leading to increased surface runoff and flash flooding.
Option D: The heat generated by urban areas does not significantly affect actual evapotranspiration in the context of flash flooding.
