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

Q.1

Alex is reviewing a research paper on atmospheric gases.
Which gases in the atmosphere contribute significantly to the greenhouse effect, aiding in climate regulation?

Q.2

Lisa and Michael are environmental consultants advising a town's energy committee on renewable energy options. The committee is debating between hydroelectric, solar, and wind power for their region's future energy needs.
Why might hydroelectric power be considered more versatile than solar or wind power?

Q.3

A town located near a geothermal hotspot is exploring various uses for geothermal energy. Considering the town's needs and available resources, where could geothermal energy be most efficiently utilised?

Q.4

What is the primary function of a hydroelectric power plant in generating electricity?

Q.5

In a small-scale wastewater treatment experiment, a student used an activated sludge process to treat a sample of domestic wastewater as represented below. The student observed a significant reduction in the BOD levels. What is the role of activated sludge in this process?

Q.6

Consider a scenario where a city implements extensive water conservation methods, reducing wastewater released into rivers by 40%. If initially, 1,000 cubic meters of wastewater flowed into rivers per day, what would be the new daily volume released after conservation efforts?

Q.7

During science class, students learned about waste separation and its significance. Which practice best aligns with responsible waste separation?

Q.8

Consider the following scenario and choose the correct option.

Scenario: You're a college student living in a shared hostel room with two other roommates. You've noticed increased common illnesses among your roommates, like colds, flu, and stomach upsets. You suspect poor hygiene might be playing a role.

Instructions: Choose the MOST LIKELY way your hygiene habits could contribute to your roommates' health problems, and explain your reasoning.

Q.9

A group of environmental scientists conducted a study on the significance of land-based environments in maintaining ecological balance. They explored various aspects ranging from biodiversity to human reliance on terrestrial ecosystems. During their research, the scientists observed a correlation between land-based environments and the overall health of marine ecosystems.

Choose an appropriate option that best reflects the importance of terrestrial ecosystems for marine life.

Q.10

Create an experiment using two plant pots, one covered with plastic wrap and the other left uncovered. Which observation would support the idea that greenhouse gases contribute to warming?
