Environmental Geology and Sustainability MCQs Questions & Answers

1

What is the purpose of buffer zones around rivers in urban planning?

A) Promote construction near riverbanks B) Reduce flood risk and pollution C) Encourage industrial use D) Store stormwater

Discuss

Answer & Solution

Answer: Option B

Solution:

Buffer zones act as green barriers that absorb runoff, reduce erosion, and protect rivers from pollution.They are key in sustainable watershed management.

2

Which of the following best describes a brownfield site?

A) Undeveloped forest area B) Pristine agricultural land C) Previously contaminated land repurposed for use D) Mountain terrain

Discuss

Answer & Solution

Answer: Option C

Solution:

A brownfield site is land previously used for industrial purposes, often requiring cleanup before redevelopment.It supports sustainable urban reuse.

3

Which activity contributes most to urban heat island effect?

A) Planting trees B) Building reflective roofs C) Dense concrete construction D) River restoration

Discuss

Answer & Solution

Answer: Option C

Solution:

Dense concrete and asphalt absorb and retain heat, significantly increasing urban temperatures compared to rural surroundings.

4

What environmental concern is linked to tailings from mining operations?

A) Soil fertility increase B) Groundwater contamination C) Increased vegetation growth D) Air purification

Discuss

Answer & Solution

Answer: Option B

Solution:

Mining tailings often contain heavy metals and toxins, which can leach into and contaminate groundwater systems.

5

What is the main goal of sustainable construction in geology?

A) Reduce project cost B) Maximize use of natural resources C) Minimize environmental impact D) Build faster

Discuss

Answer & Solution

Answer: Option C

Solution:

Sustainable construction focuses on reducing carbon footprint, waste, and environmental damage during infrastructure development.

6

Which renewable energy source depends directly on subsurface geological heat?

A) Solar B) Biomass C) Geothermal D) Hydroelectric

Discuss

Answer & Solution

Answer: Option C

Solution:

Geothermal energy harnesses the Earth's internal heat for electricity and heating, making it clean and sustainable.

7

Which soil characteristic is most relevant in evaluating flood risk?

A) Plastic limit B) Moisture content C) Permeability D) Particle shape

Discuss

Answer & Solution

Answer: Option C

Solution:

Permeability affects how quickly water infiltrates or accumulates.Low permeability increases surface runoff and flood potential.

8

What is the term for managing resources to meet present needs without compromising future generations?

A) Economic development B) Environmental geology C) Sustainable development D) Urban planning

Discuss

Answer & Solution

Answer: Option C

Solution:

Sustainable development integrates economic, environmental, and social factors for long-term environmental health and human welfare.

9

Which human activity accelerates coastal erosion?

A) Mangrove planting B) Building seawalls C) Sand mining D) Coral reef conservation

Discuss

Answer & Solution

Answer: Option C

Solution:

Sand mining removes natural barriers and weakens shoreline stability, exacerbating coastal erosion and habitat loss.

10

Which of the following is a goal of environmental geology?

A) To explore minerals only B) To design skyscrapers C) To prevent or mitigate natural hazards D) To develop fossil fuels

Discuss

Answer & Solution

Answer: Option C

Solution:

Environmental geology applies geological knowledge to solve environmental problems such as landslides, groundwater pollution, and waste disposal.
