International Green Warrior Olympiad Class 10 Previous Year Papers

Q.1

A team of environmentalists is proposing the establishment of a protected area that integrates conservation efforts with sustainable development. This proposed area aims to safeguard biodiversity while allowing human activities that are compatible with nature conservation.
Which type of protected area aligns best with the team's objectives?

Q.2

You are watching a wildlife documentary where a pod of migrating humpback whales suddenly changed their course, avoiding a polluted area in the river. It was later shown that the scientists discovered high levels of mercury in the water.
How could this pollution potentially threaten the whales?

1. Weaken their immune system
2. Damage their nervous system, impacting movement
3. Blur their vision, hindering navigation and hunting

Q.3

A small community in a rural area relies on a well for its drinking water. However, recent tests have shown that the well water is contaminated with bacteria. The community is concerned about the health risks posed by the contaminated water and is considering various options for addressing the problem.
Which of the following options would be the most effective, sustainable and long-term solution for the community to protect its drinking water source?

1. Install a water filtration system at the well.
2. Educate the community about the importance of proper sanitation practices.
3. Find a new source of drinking water, such as a bottled water supplier.

Q.4

Consider the case study given below and answer the following question:

Case Study: The Müller Family's Journey to Renewable Energy

The Müller family, residing in a charming village in the German countryside, had always been conscious about their environmental impact. In 2022, they decided to take an active step towards a greener lifestyle by installing a rooftop solar panel system. Their primary motivation was to reduce their reliance on fossil fuels and contribute to mitigating climate change. However, as they embarked on this journey, they discovered a plethora of other benefits:

Environmental Benefits:
-Reduced Carbon Footprint: The solar panels generated clean energy, leading to a significant reduction in their carbon emissions. This translated to a cleaner environment for their family, their community, and the planet.
-Improved Air Quality: By relying less on fossil fuels, the Müllers contributed to cleaner air in their region, which improved their overall health and well-being.

Financial Benefits:
-Reduced Electricity Bills: The solar panels generate enough electricity to cover a significant portion of their household energy needs, resulting in substantial savings on their monthly electricity bills. This provided them with financial stability and freed up resources for other expenses.
-Government Incentives: The German government offers various financial incentives for individuals and families adopting renewable energy solutions. The Müllers took advantage of these incentives, further reducing the cost of their solar panel system and accelerating their return on investment.

Lifestyle Benefits:
-Energy Independence: The Müllers achieved a sense of energy independence by generating their own clean energy. This gave them greater control over their energy consumption and reduced their dependence on the national grid, especially during peak hours.
-Enhanced Home Value: Homes with renewable energy systems are becoming increasingly sought-after, leading to a potential increase in the value of the Müller's property.

Overall Impact:
The Müller family's experience showcases the numerous benefits of adopting renewable energy in a domestic setting. Their commitment to environmental sustainability not only helped them create a cleaner future but also resulted in financial savings and enhanced their quality of life. Their story serves as an inspiration for others to consider switching to renewable energy and contribute to a more sustainable future.

Which of the following statements best describes the primary motivation of the Müller family to switch to renewable energy?

1. Environmental sustainability
2. Financial savings
3. Increased energy independence
4. Minimising the environmental impact

Q.5

A municipality is debating between establishing a waste-to-energy incineration plant or a biogas plant for managing its organic waste. Which option would be more environmentally sustainable, considering the waste reduction and energy generation potential?

Q.6

A small town located in a desert region is experiencing frequent power outages due to an ageing grid infrastructure. The town council is considering investing in renewable energy to improve energy security and reduce reliance on the grid. The system needs to be reliable, cost-effective, and able to meet the community's energy needs throughout the year.
Which combination of renewable energy sources would be the most appropriate for this project?

Q.7

In a workshop discussing electronic waste reduction, participants explore devices that are more susceptible to shorter lifespans because of rapid advancements in technology and frequent model upgrades. Which of the following devices is MOST prone to shorter lifespans due to these factors?

Q.8

A scientist is studying the effects of climate change on a tropical rainforest. She measures the amount of water vapour in the atmosphere and finds that it has increased by 10% over the past decade. What does this suggest?

Q.9

A local river, which serves as a crucial water source for the community, has been experiencing deteriorating water quality. Which parameter is primarily used to indicate organic pollution in freshwater systems?

Q.10

The following table shows the average temperature and precipitation for three different biomes. Based on your understanding, answer the following questions.

A. Which biome is expected to experience the most severe drought stress due to reduced rainfall?
B. Which biome is expected to experience the most significant changes in soil drainage and nutrient availability due to melting permafrost?
C. Which biome is expected to experience the changes in the distribution of oak species due to rising temperatures?
