Environmental Geology and Sustainability MCQs Questions & Answers

1

What is the primary goal of environmental geology?

A) Study of rocks only B) Understanding human impacts on the environment C) Mining of minerals D) Construction of buildings

Discuss

Answer & Solution

Answer: Option B

Solution:

Environmental geology studies interactions between humans and the geological environment.Its primary goal is to minimize environmental hazards and promote sustainable resource use.

2

Which of the following is a major cause of soil erosion?

A) Vegetation cover B) Deforestation C) Urbanization D) Irrigation

Discuss

Answer & Solution

Answer: Option B

Solution:

Deforestation removes protective vegetation, increasing soil exposure.This leads to accelerated soil erosion by wind and water.

3

What does sustainability mean in geological engineering?

A) Using all available resources B) Maintaining ecological balance while using resources C) Ignoring environmental impacts D) Rapid industrial growth

Discuss

Answer & Solution

Answer: Option B

Solution:

Sustainability focuses on meeting current needs without compromising future generations.In geology, it means responsible use of earth materials and minimizing environmental damage.

4

Acid rain primarily results from which of the following?

A) Carbon dioxide and water B) Sulfur dioxide and nitrogen oxides C) Methane and oxygen D) Hydrogen and carbon monoxide

Discuss

Answer & Solution

Answer: Option B

Solution:

Acid rain is caused by sulfur dioxide (SO?) and nitrogen oxides (NO?) emissions.These gases react with water vapor to form acidic precipitation, damaging ecosystems.

5

Which geological process can lead to contamination of groundwater?

A) Volcanic eruptions B) Land subsidence C) Leaching of pollutants from waste dumps D) Earthquake faulting

Discuss

Answer & Solution

Answer: Option C

Solution:

Leaching occurs when pollutants from waste sites dissolve and migrate through soil layers.This contaminates the groundwater, posing health risks.

6

What is the term for the reduction of soil fertility due to natural or human causes?

A) Soil erosion B) Soil degradation C) Soil compaction D) Soil liquefaction

Discuss

Answer & Solution

Answer: Option B

Solution:

Soil degradation refers to the decline in soil quality and productivity.It can be caused by erosion, pollution, salinization, or improper land use.

7

Which of the following is a renewable geological resource?

A) Coal B) Natural gas C) Groundwater D) Iron ore

Discuss

Answer & Solution

Answer: Option C

Solution:

Groundwater can be replenished naturally through precipitation and infiltration.Unlike fossil fuels or minerals, it is considered renewable if managed properly.

8

What is the main environmental concern associated with mining activities?

A) Increased vegetation B) Habitat destruction and pollution C) Increased rainfall D) Soil formation

Discuss

Answer & Solution

Answer: Option B

Solution:

Mining often causes habitat loss, soil erosion, and water pollution.Proper environmental management is required to mitigate these impacts.

9

What geological hazard is associated with subsidence due to groundwater withdrawal?

A) Landslides B) Sinkholes C) Flooding D) Earthquakes

Discuss

Answer & Solution

Answer: Option B

Solution:

Subsidence is the sinking of land caused by excessive groundwater pumping.This can cause sinkholes, damage to structures, and altered drainage.

10

Which method is commonly used to remediate contaminated soil?

A) Bioremediation B) Excavation only C) Compaction D) Irrigation

Discuss

Answer & Solution

Answer: Option A

Solution:

Bioremediation uses microorganisms to degrade pollutants.It is an eco-friendly and effective method for soil cleanup.
