Explanation - Urban sprawl refers to uncontrolled expansion of cities into surrounding rural land, often leading to environmental degradation.
Correct answer is: Urban sprawl
Q.8 Which of the following is an effect of improper urban waste management?
Increased agricultural productivity
Spread of diseases
Decline in urban population
Improved air quality
Explanation - Improper disposal of solid and liquid waste can contaminate water and attract disease vectors, causing public health issues.
Correct answer is: Spread of diseases
Q.9 Which of these measures can help reduce traffic congestion in cities?
Promoting private car use
Building wider roads only
Developing public transport systems
Reducing bicycle lanes
Explanation - Efficient public transport reduces the number of private vehicles on the road, decreasing traffic congestion and emissions.
Correct answer is: Developing public transport systems
Q.10 Which term describes the decline of city centers as people move to suburbs?
Suburbanization
Urban decay
Urban renewal
Gentrification
Explanation - Urban decay occurs when city centers deteriorate due to depopulation, poor maintenance, and economic decline.
Correct answer is: Urban decay
Q.11 Which of the following is a direct consequence of deforestation for urban development?
Urban heat island effect
Increased rainfall
Reduced pollution
Better soil fertility
Explanation - Removing trees for urban development reduces shade and vegetation, contributing to higher urban temperatures.
Correct answer is: Urban heat island effect
Q.12 Which urbanization-related problem is most closely linked to climate change?
Noise pollution
Air pollution and greenhouse gas emissions
Traffic congestion
Loss of public parks
Explanation - Urbanization increases energy use and emissions, contributing to greenhouse gas accumulation and climate change.
