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

Q.1

A family decides to install solar panels on their roof to generate electricity. How does this contribute to responsible energy consumption?

Q.2

During a school project on recycling, Emma was tasked with investigating the environmental benefits of recycling aluminium cans versus manufacturing new ones.

Which of the following statements is true regarding this comparison?

1. Recycling aluminium cans saves energy but does not reduce pollution.
2. Manufacturing new aluminium cans consumes less energy than recycling them.
3. Recycling aluminium cans reduces energy consumption and environmental pollution.
4. Manufacturing new aluminium cans have no impact on energy consumption or pollution.

Q.3

You're advising a friend on reducing their ecological footprint through dietary changes. Which practical suggestion aligns best with this goal?

Q.4

In the following question, you will find an assertion and a reason. Select the appropriate option that applies.

Assertion: While deserts like the Sahara are notoriously arid, some coastal regions also experience water scarcity.
Reason: Rising sea levels due to climate change can contaminate freshwater sources with saltwater intrusion.

Q.5

Sophie and her marine biology class were on a research vessel exploring marine life near the coast. Suddenly, they noticed a distressed pod of dolphins swimming amidst an oil slick that stretched for miles. Investigating further, they realised it was the result of a tanker accident, causing severe repercussions for the marine environment.

Sophie and her classmates witnessed an oil spill from a tanker that affected the surrounding ocean. How does this type of marine pollution primarily impact marine ecosystems?

Q.6

A study in a river basin area shown in the picture reveals that the concentration of heavy metals in the water significantly exceeds permissible limits downstream of an industrial area. What can be inferred from this data?

Q.7

A school implemented water-saving methods, reducing daily usage by 15%. If the school previously consumed 500 liters of water per day, what is the new daily consumption after applying these strategies?

Q.8

In a local community initiative, Sarah's school decided to promote recycling. They collected plastic bottles, newspapers, and aluminium cans. What's the primary advantage of recycling these materials?

Q.9

Javier studied the adaptations of desert organisms. He discovered that certain desert plants have shallow roots but spread extensively.

What advantage do these shallow, widespread roots offer to desert plants?

Q.10

Sarah is a teacher at an elementary school. She collects scrap paper from her students and uses the blank sides for drawing, thereby extending the life of the paper before recycling it.

What is Sarah doing in this scenario to contribute to waste reduction and sustainability?
