What is the main cause of landslides in deforested areas?

A) Increase in vegetation B) Removal of root reinforcement C) Increased rainfall absorption D) Soil compaction

Discuss

Answer & Solution

Answer: Option B

Solution:

Removal of root reinforcement due to deforestation reduces soil stability.Roots help bind soil, preventing landslides.

Which practice helps in sustainable groundwater management?

A) Over-extraction B) Artificial recharge C) Unregulated drilling D) Polluting recharge zones

Discuss

Answer & Solution

Answer: Option B

Solution:

Artificial recharge involves adding water to aquifers to replenish groundwater, ensuring sustainable use.

What type of rock is most susceptible to chemical weathering causing sinkholes?

A) Granite B) Limestone C) Basalt D) Sandstone

Discuss

Answer & Solution

Answer: Option B

Solution:

Limestone is susceptible to dissolution by acidic groundwater, leading to karst landscapes and sinkholes.

Which of the following gases is a significant greenhouse gas contributing to global warming?

A) Oxygen B) Carbon dioxide C) Nitrogen D) Argon

Discuss

Answer & Solution

Answer: Option B

Solution:

Carbon dioxide (CO?) traps heat in the atmosphere, significantly contributing to the greenhouse effect and global warming.

What is the main environmental concern with mining activities?

A) Soil erosion and habitat destruction B) Increasing water table C) Enhancing soil fertility D) Reducing air pollution

Discuss

Answer & Solution

Answer: Option A

Solution:

Mining often causes soil erosion, habitat loss, and pollution of air and water resources.

What is meant by �sustainable development� in environmental geology?

A) Development without environmental consideration B) Meeting present needs without compromising future generations C) Unlimited resource use D) Rapid urbanization

Discuss

Answer & Solution

Answer: Option B

Solution:

Sustainable development balances current development needs while preserving resources and environment for future generations.

What role do wetlands play in environmental sustainability?

A) Increase pollution B) Filter pollutants and provide habitat C) Cause soil erosion D) Increase groundwater contamination

Discuss

Answer & Solution

Answer: Option B

Solution:

Wetlands act as natural filters, improving water quality and supporting biodiversity.

What is the primary pollutant responsible for ozone layer depletion?

A) Carbon dioxide B) Methane C) Chlorofluorocarbons (CFCs) D) Sulfur dioxide

Discuss

Answer & Solution

Answer: Option C

Solution:

CFCs break down ozone molecules in the stratosphere, causing ozone layer depletion.

Which type of waste is biodegradable and suitable for composting?

A) Plastic B) Organic kitchen waste C) Glass D) Metals

Discuss

Answer & Solution

Answer: Option B

Solution:

Organic kitchen waste breaks down naturally and can be composted to enrich soil.

What is the consequence of over-pumping groundwater in coastal areas?

A) Increased freshwater availability B) Saltwater intrusion into aquifers C) Reduced soil salinity D) Increased rainfall

Discuss

Answer & Solution

Answer: Option B

Solution:

Over-pumping lowers freshwater tables, allowing seawater to intrude, contaminating aquifers with saltwater.
