Impacts of Humans on Antarctica

What is a significant effect of climate change on Antarctica's ice sheets?

• Increased ice formation

• Decreased albedo effect

• Reduced ice melting

• Enhanced ice thickness

Answer explanation

The correct answer is 'Decreased albedo effect' because as ice melts, it exposes darker surfaces, which absorb more heat and contribute to further melting.

Why is biodiversity conservation important in Antarctica?

• To increase tourism

• To maintain ecological balance

• To promote commercial fishing

• To enhance global warming

Answer explanation

Biodiversity conservation in Antarctica is important to maintain ecological balance by preserving the unique and delicate ecosystems in the region.

What is a major concern regarding resource exploitation in Antarctica?

• Overpopulation

• Air pollution

• Overfishing

• Increased rainfall

Answer explanation

The major concern regarding resource exploitation in Antarctica is overfishing, as it can disrupt the delicate balance of the ecosystem and lead to irreversible damage.

Which treaty is primarily responsible for the preservation of Antarctica?

• The Paris Agreement

• The Antarctic Treaty

• The Kyoto Protocol

• The Montreal Protocol

Answer explanation

The Antarctic Treaty is primarily responsible for the preservation of Antarctica.

How does international cooperation contribute to Antarctica's preservation?

• By promoting oil drilling

• By sharing research and resources

• By increasing commercial activities

• By reducing scientific expeditions

Answer explanation

International cooperation contributes to Antarctica's preservation by sharing research and resources, which allows for better understanding and management of the region's unique ecosystem.

What role does research and monitoring play in understanding Antarctica's ecosystems?

• Decreases biodiversity

• Increases global warming

• Helps in policy making

• Reduces international cooperation

Answer explanation

Research and monitoring help in policy making by providing valuable data and insights into Antarctica's ecosystems, which can inform decision-making and conservation efforts.

What is the impact of climate change on Antarctic marine life?

• Increased food availability

• Decreased sea ice habitat

• Reduced water temperatures

• Enhanced species diversity

Answer explanation

The impact of climate change on Antarctic marine life includes decreased sea ice habitat, which affects the ecosystem and the species that rely on it.

Why is the conservation of Antarctic krill important?

• They are a primary food source for many species

• They contribute to global warming

• They are a major pollutant

• They decrease biodiversity

What is a potential consequence of unregulated tourism in Antarctica?

• Improved biodiversity

• Increased scientific research

• Environmental degradation

• Enhanced international cooperation

Answer explanation

Unregulated tourism in Antarctica can lead to environmental degradation due to increased human impact on the fragile ecosystem.

How does melting Antarctic ice affect global sea levels?

• Decreases sea levels

• Increases sea levels

• No effect on sea levels

• Stabilizes sea levels

Answer explanation

Melting Antarctic ice increases global sea levels due to the addition of more water into the oceans.
