Q542. Consider the following statements regarding the mechanisms of the Paris Agreement:
I. It includes a "Global Stocktake" every five years to assess collective progress toward its long-term goals.
II. Developing countries are explicitly prohibited from setting their own emission reduction targets.
III. It establishes a framework for voluntary cooperation and market mechanisms (Article 6).
Which of the above statement(s) is/are correct?
I. It includes a "Global Stocktake" every five years to assess collective progress toward its long-term goals.
II. Developing countries are explicitly prohibited from setting their own emission reduction targets.
III. It establishes a framework for voluntary cooperation and market mechanisms (Article 6).
Which of the above statement(s) is/are correct?
Explanation
The Paris Agreement has a Global Stocktake every five years and a framework for voluntary cooperation under Article 6. Developing countries are not prohibited from setting targets, since each country sets its own, so II is wrong.
Q543. In the context of global warming, what is the difference between eustatic and isostatic sea-level changes?
Explanation
Eustatic sea-level change is a change in the volume of ocean water, while isostatic change is a change in the level of the land, such as rebound after the ice melts.
Q544. According to recent Space Applications Centre (SAC) reports, approximately what percentage of the total geographical area of India is undergoing desertification/land degradation?
Explanation
According to the Space Applications Centre, around 30 per cent of India’s geographical area is undergoing land degradation and desertification.
Q545. Consider the following statements regarding strategies to combat climate change:
I. Mitigation involves taking action to reduce the emissions that cause climate change.
II. Adaptation involves adjusting to actual or expected future climate impacts.
III. Carbon Capture and Storage (CCS) is a widely deployed adaptation strategy in developing countries.
IV. Enhancing natural carbon sinks through afforestation is considered a mitigation strategy.
V. The Paris Agreement requires all countries to implement identical mitigation technologies regardless of their economic status.
Which of the above statement(s) is/are correct?
I. Mitigation involves taking action to reduce the emissions that cause climate change.
II. Adaptation involves adjusting to actual or expected future climate impacts.
III. Carbon Capture and Storage (CCS) is a widely deployed adaptation strategy in developing countries.
IV. Enhancing natural carbon sinks through afforestation is considered a mitigation strategy.
V. The Paris Agreement requires all countries to implement identical mitigation technologies regardless of their economic status.
Which of the above statement(s) is/are correct?
Explanation
Climate action involves both mitigation, which reduces emissions, and adaptation, which builds resilience to impacts. Afforestation is a key mitigation strategy as it enhances natural carbon sinks. However, complex technologies like Carbon Capture and Storage are not yet widely deployed in developing nations. Furthermore, the Paris Agreement recognizes different national circumstances, allowing for a variety of approaches rather than mandating identical technologies.
Q546. Enteric fermentation is a major source of greenhouse gas emissions. This process is primarily associated with:
Explanation
Enteric fermentation is a natural digestive process occurring in ruminant animals like cattle, sheep, and goats. Microorganisms in the rumen break down plant material, producing methane as a byproduct, which is then released into the atmosphere. This process is a significant anthropogenic source of methane, making livestock management a key area for reducing agricultural greenhouse gas emissions and addressing global warming.
Q547. Match List-I with List-II regarding the impacts of climate change on specific ecosystems:
Select the correct answer from the codes given below:
| Ecosystem | Specific Impact |
|---|---|
| A. Coral Reefs | i. Widespread bleaching events due to thermal stress |
| B. Arctic Tundra | ii. Accelerated permafrost thaw releasing trapped greenhouse gases |
| C. Tropical Rainforests | iii. Increased vulnerability to sea-level rise and coastal squeeze |
| D. Coastal Mangroves | iv. Heightened risk of desiccation and increased frequency of forest fires |
Explanation
Different ecosystems face unique threats from climate change. Coral reefs are highly sensitive to thermal stress, leading to bleaching. The Arctic tundra is impacted by permafrost thaw, which releases greenhouse gases. Tropical rainforests face higher risks of fire and drying. Coastal mangroves are vulnerable to rising sea levels and limited space for landward migration. Recognizing these specific vulnerabilities is crucial for targeted conservation.
Q548. Which component of anthropogenic activities provides the single largest positive contribution to global radiative forcing (warming effect) since pre-industrial times?
Explanation
Since the industrial revolution, human activities have altered the Earth’s energy balance. While various factors like methane and aerosols contribute to radiative forcing, carbon dioxide from burning fossil fuels provides the largest positive contribution. Its long atmospheric lifetime and high total emissions make it the primary driver of observed global warming. Reducing CO 2 levels is therefore the most critical priority for stabilizing the climate.
Q549. Given below are two statements, one labelled as
Assertion (A) and the other as Reason (R):
Assertion (A): The Paris Agreement represented a shift from the rigid, top-down approach of the Kyoto Protocol to a more flexible, bottom-up approach.
Reason (R): Under the Paris Agreement, emission reduction targets (NDCs) are self-determined by each individual country based on their national circumstances.
Select the correct answer from the codes given below:
Assertion (A) and the other as Reason (R):
Assertion (A): The Paris Agreement represented a shift from the rigid, top-down approach of the Kyoto Protocol to a more flexible, bottom-up approach.
Reason (R): Under the Paris Agreement, emission reduction targets (NDCs) are self-determined by each individual country based on their national circumstances.
Select the correct answer from the codes given below:
Explanation
The transition to the Paris Agreement marked a significant change in international climate policy. By moving away from the rigid targets of the Kyoto Protocol, the agreement adopted a bottom-up model. This allows each nation to determine its own contributions based on local capacity and priorities. This flexibility was essential for achieving near-universal participation, ensuring that both developed and developing countries contribute.
Q550. Which of the following statements concerning the global extent of deforestation is INCORRECT?
Explanation
While tropical regions have historically faced the highest rates of forest loss, Boreal forests in Russia and Canada are not immune to human impacts. These areas are subject to significant commercial logging for timber and paper industries. Additionally, climate-induced factors like increased pest outbreaks and more frequent wildfires also threaten these ecosystems. Understanding that all forest types face pressures is vital for global conservation.Answer key for these questions

Key facts from World Geography
- The RPSC syllabus for world geography lists mountains, plateaus, plains and deserts, major rivers and lakes, natural vegetation, agriculture, industrial regions, transport and environmental issues.
- Questions ask for the location of a feature: where a range lies, where a river ends, which country has an industrial region.
- Statement and sequence questions are common, for example the order of mountain ranges or of vegetation layers.
- Environmental issues are asked through treaties and dates, such as the Montreal Protocol, the IPCC and the Paris Agreement.
- Indian and Rajasthan geography are on their own pages, each with its own chapters.
