Q.1

A farmer uses a private well to irrigate his crops. He notices that the well water has become increasingly salty over the past few years, affecting the growth and yield of his crops.
What could be the most likely reason for this increase in salinity?

Q.2

A family living in a region with abundant clean hydropower is considering replacing their ageing gas oven with a new electric model. However, they are concerned about the overall environmental impact of each option.

Q.3

During a science fair, a student presented a project on the impact of wildfires on climate change. They highlighted that wildfires release vast amounts of carbon dioxide, methane and nitrous oxide into the atmosphere as shown in the table given below.
What inference can be made from this presentation?
1. Wildfires can act as a positive feedback loop, contributing to further warming and potentially more frequent fires.
2. Wildfires are primarily responsible for the rising levels of greenhouse gases in the atmosphere.
3. All wildfires should be suppressed to prevent any carbon dioxide, methane and nitrous oxide emissions.
4. The release of greenhouse gases from wildfires is balanced by the absorption of carbon dioxide by new plant growth.

Greenhouse Gas Amount Before Wildfire (tons) Amount Released by Wildfire (tons) Increase (%)
Carbon Dioxide
(CO2)
30,00,000 10,00,000 33.33%
