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

A research team investigated the effects of climate change on the migration patterns of marine species. What implications can changing migration patterns have on marine ecosystems, and how might this impact human communities reliant on these species for sustenance?

Q.3

Considering the impact of climate change, which of the following species is likely to face the highest risk of endangerment?

1. A migratory bird species
2. A deep-sea fish species
3. A reptile species in a tropical forest

Q.4

Which change in agricultural practices leads to more carbon dioxide being released into the atmosphere?

Q.5

Analyse the graph below representing the water consumption patterns of a city over five years.
Identify the trend in water consumption and propose a hypothesis explaining the observed pattern.

Q.6

You've been tasked with managing a community composting project. Over a period of 20 days, you monitored the temperature changes within the compost pile.
Based on the data depicted in the graph below, what could be the likely reason behind the observed fluctuations in temperature throughout the composting process?

Q.7

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.
