Which of the following indirect consequences is likely to negatively affect ecosystems due to this mining activity?

Q.5	Over-extraction of groundwater can lead to various negative consequences. Which of the following is NOT a potential consequence of excessive groundwater extraction?

Q.6	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.7	During a summer heatwave, a meteorological study compares temperature variations between an urban area and its nearby rural surroundings. The findings are provided in the graph below. Which of the statement(s) accurately describes the observed temperature variations between the urban and rural areas? 1. Urban areas generally have lower vegetation cover, leading to increased temperatures due to reduced shade and less evaporative cooling. 2. The urban areas have more concrete and asphalt surfaces, retaining more heat. 3. Decreased wind circulation in the rural area causes temperature drops. 4. Rural areas contain more open spaces, facilitating better air circulation and lower temperatures.

Q.8	A coastal area witnesses a significant decrease in the population of shellfish due to water contamination. Analysis reveals the presence of persistent organic pollutants (POPs). POPs are resistant to environmental degradation through chemical, biological, and photolytic processes. For this reason, they persist in the environment for a long time. Which method is most effective in reducing POPs in aquatic environments?

Q.9	Consider the case study given below and answer the following question: Title: Forests as Crucial Carbon Capture Systems Forests play a critical role in mitigating climate change by capturing and storing carbon dioxide from the atmosphere. Trees absorb carbon dioxide through photosynthesis and use it to grow. The carbon is then stored in the tree's biomass (wood, leaves, branches, and roots) and soil. Forests also help to regulate the climate by releasing water vapour into the atmosphere, which can form clouds and reflect sunlight back into space. Trees are the most significant carbon sink in forests, storing carbon in their biomass. The amount of carbon stored in a tree depends on its species, size, and age. Young forests capture carbon rapidly due to the quick growth of trees. Middle-aged forests store relatively greater amounts of carbon as trees grow slower but sequester more carbon. Old-growth forests contain large trees that retain carbon for extended periods, albeit at a slower rate due to fewer trees overall. Forest soils contain diverse forms of carbon influenced by soil type, vegetation, and geography. Soil properties, such as high organic content or frozen conditions, significantly impact carbon storage potential. The carbon captured by forests is eventually returned to the atmosphere through processes like decomposition and respiration. Different forest types exhibit varying rates of carbon capture and release. Tropical forests capture carbon rapidly but can release it quickly too. In contrast, temperate forests offer a balanced solution. Effective management strategies, such as forest preservation, sustainable forestry practices, forest expansion, and invasive species control, are crucial in optimising carbon sequestration potential while maintaining ecosystem balance. A farmer is contemplating converting a section of their farmland into a forest to optimise carbon sequestration potential. Which set of actions would best help the farmer achieve this goal? 1. Plant a mix of tree species known for fast growth and high carbon storage capacity. 2. Plant trees that are native to the region. 3. Leave the soil unplanted and unattended to encourage natural regeneration of native vegetation.

Q.10	A community relies on a rainwater harvesting system for its water supply. The system collects rainwater from rooftops and stores it in large underground tanks. After a heavy rainfall, the residents notice that the stored water has a brownish colour and an unpleasant odour. What could be the most likely cause of this contamination? 1. Insufficient filtration and disinfection of the rainwater 2. Accumulation of organic debris in the storage tanks 3. Leaching of pollutants from roofing materials
