These resources are available for Geological engineering students who wish to clear GATE exams, technical interviews, competitive examinations, and other entrance exams. The Environmental Geology and Sustainability chapter is particularly important for students studying Geological engineering. Page-2 section-1

Each section contains 100 MCQs on Environmental Geology and Sustainability .
11
What is the significance of a geological hazard map?
Discuss
Answer & Solution
Answer: Option B
Solution:
Geological hazard maps display areas vulnerable to landslides, earthquakes, floods, etc.This information helps in risk assessment and land-use planning.
12
Which gas is primarily responsible for the greenhouse effect?
Discuss
Answer & Solution
Answer: Option C
Solution:
Carbon dioxide (CO?) traps infrared radiation in the atmosphere.This causes the greenhouse effect, leading to global warming and climate change.
13
What is the purpose of an Environmental Impact Assessment (EIA)?
Discuss
Answer & Solution
Answer: Option B
Solution:
EIA systematically assesses the possible environmental consequences before project approval.It promotes sustainable development and hazard mitigation.
14
Which soil property affects its ability to filter contaminants?
Discuss
Answer & Solution
Answer: Option A
Solution:
Soil texture (proportion of sand, silt, clay) influences permeability.Finer soils filter contaminants better, but may have slower infiltration.
15
How can urbanization affect local geological conditions?
Discuss
Answer & Solution
Answer: Option C
Solution:
Urbanization creates impervious surfaces reducing infiltration.This leads to increased runoff, flooding risk, and soil erosion.
16
What is the main cause of land degradation in arid regions?
Discuss
Answer & Solution
Answer: Option A
Solution:
Overgrazing removes vegetation cover, leading to soil erosion and desertification.This is a major cause of land degradation in arid and semi-arid areas.
17
Which of the following best describes a sustainable water management practice?
Discuss
Answer & Solution
Answer: Option B
Solution:
Rainwater harvesting collects and stores rainwater for use.This reduces dependency on groundwater and helps sustainability.
18
Which geological phenomenon is a major contributor to tsunami generation?
Discuss
Answer & Solution
Answer: Option A
Solution:
Undersea earthquakes displace large volumes of water, causing tsunamis.This is the primary natural cause of tsunami events.
19
Which pollutant is most commonly associated with groundwater contamination from agriculture?
Discuss
Answer & Solution
Answer: Option B
Solution:
Nitrates from fertilizers infiltrate soil and contaminate groundwater.High nitrate levels can cause serious health issues like methemoglobinemia.
20
What is the main impact of climate change on geological hazards?
Discuss
Answer & Solution
Answer: Option B
Solution:
Climate change intensifies extreme weather such as heavy rains and droughts.This leads to increased risk of landslides, floods, and erosion.
