Q.1 Q.2 Q.3 Q.4 Q.5 Q.6 Q.7 Q.8 Q.9 Q.10

Q.1

Coastal regions have been experiencing a rise in sea surface temperatures due to climate change, causing concern among local communities and authorities. As part of a coastal environmental study project, your team is investigating the potential impact of this situation.
Based on your research and understanding, which extreme weather event is expected to become more severe or frequent in coastal areas due to climate change ?

Q.2

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

Case Study: Water Conservation in Singapore

Singapore, a water-scarce nation, implemented innovative strategies for water conservation and efficient use. One notable initiative is the "NEWater" program, where wastewater is treated extensively to produce high-grade reclaimed water. This reclaimed water is then used for industrial processes, cooling systems, and even direct consumption after rigorous purification. Additionally, Singapore employs an extensive rainwater harvesting system, collecting rainwater on a large scale for non-potable uses like flushing toilets and watering plants. These initiatives have not only reduced the strain on the city-state's water supply but also ensured sustainable water management for the growing population.

As a city planner, how would you promote the adoption of similar water conservation strategies in a different urban area facing water scarcity?

Q.3

A family went on a camping trip and drank water from an untreated stream. Several days later, they all became ill with vomiting and diarrhoea. Which of the following is the most likely cause of their illness?

1. Contaminated water from the stream
2. Ingestion of a parasite present in the stream water
3. A contagious respiratory illness

Q.4

Imagine you are a city planner. How would you design a new urban development project to ensure the preservation of green spaces and natural habitats while meeting the housing needs of the growing population?

Q.5

The government of a city wants to switch to renewable energy sources to help the environment. Which of the following strategies could the city use to promote renewable energy adoption and reduce environmental impact?

Q.6

Blair, an environmentally conscious consumer, is shopping for groceries at a local store. She notices a food product with an eco-label that states "Organic" on the packaging. Curious about its meaning, she checks the information available to understand the significance of the label.

In the context of eco-labelling, what does the presence of an "Organic" label on a food product signify based on Emily's observation?

Q.7

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

Case Study: Threats to Marine Life

In the North Atlantic, a large ship accident caused a massive oil spill. This spill polluted the ocean, covering the surface and spreading deep into the water. The oil mixed with floating plastic waste, created dangerous clumps that harmed marine animals and spread toxic chemicals.
Furthermore, the surrounding coastal regions experienced heavy industrial runoff from nearby factories and agricultural waste from farms that drain into rivers and streams, carrying excessive nutrients like nitrogen and phosphorus.
The combination of oil slicks, entangled plastic debris, and toxic algal blooms severely impacts the local fishing industry, leading to economic downturns and food scarcity in nearby communities reliant on marine resources. The spill also results in long-term ecological damage, affecting critical habitats such as coral reefs, seagrass beds, and estuaries, disrupting entire ecosystems.
This situation shows how different kinds of marine pollution, all come together to make things worse for ocean life and the people who depend on it. It is crucial for us to find ways to prevent and clean up these types of pollution to protect our oceans and the creatures living in them.

In a region where algal blooms have caused a significant decrease in oxygen levels, which species is most likely to suffer the most adverse effects?

Q.8

During an Earth Science field trip, students are exploring the impact of rising temperatures on the local ecosystem. The students notice a decline in the population of a particular plant species in the area compared to previous years.
Which factor related to climate change is most likely influencing this decline?

Q.9

Carbon emissions from anthropogenic sources contribute to the greenhouse effect, trapping heat in the Earth's atmosphere. Which of the following best describes the mechanism by which carbon dioxide (CO2) traps heat?

Q.10

A tropical rainforest guide notices that a particular group of trees is flowering much earlier than usual. This phenomenon of early flowering has been going on for quite some time now. He wonders what might be causing this unusual phenomenon.

What could be a potential explanation for the early flowering of these trees?

1. Unusually warm temperatures due to climate change mimicking the typical flowering season.
2. A sudden increase in rainfall has triggered early bud formation.
3. The trees have undergone a genetic mutation that has changed their flowering cycle.
