Application-Based Questions
Monsoon and Agriculture
Q1. In June, a farmer in central India intends to plant his crops. Nevertheless, the monsoon arrives two weeks later than normal, and there is little rainfall for a few weeks.
Describe how the region’s water supply and agricultural operations may be impacted by this delay. Provide a potential risk-reduction strategy for the farmer.
ANSWER: The region’s water supply and agricultural operations may be impacted as follows:
Firstly – Delayed sowing: Late monsoon can delay sowing of rain-fed crops and shorten the growing season.
Secondly – Lower soil moisture: Periods without rain can delay seed germination and impact early crop growth.
Thirdly – Water shortage: Reduced monsoon rainfall could result in lower groundwater recharge, reservoir levels and water availability for irrigation.
Fourthly – Reduced crop yield: Prolonged dry spells can lead to moisture stress and diminished crop productivity.
Next – Higher irrigation demand: Farmers may have to rely more on wells, canals or other irrigation sources.
Economic impact: Low rainfall may increase the cost of cultivation and reduce the income of farmers.
Lastly – Risk-reduction strategy: The farmer can grow drought-resistant, short-duration crops and use efficient irrigation methods such as drip irrigation to conserve water.
Atmospheric Layers
Q2. An airplane is operating at a very high altitude, where weather disruptions are rare, and cloud formation is negligible.
Compared to the area close to the Earth’s surface, the pilot notes that things are far more stable.
Describe why flying at such altitudes can be beneficial & identify the atmospheric layer where such steady circumstances are likely
to be encountered.
ANSWER: Flying at such altitudes can be beneficial for the following reasons:-
Atmospheric layer:
Such stable conditions are usually found in the lower stratosphere , above the troposphere .
Fewer Weather Events:
The stratosphere is relatively quiet since most clouds, storms, rainfall and other weather events take place in the troposphere.
Smoother Flight:
At the right altitudes in the lower stratosphere, aircraft can fly smoother and with less disturbance and turbulence.
Fuel Efficiency:
Higher altitude flights can reduce air resistance, which can improve fuel efficiency.
Better Visibility:
Most clouds and weather patterns are absent, resulting in clearer atmospheric conditions.
Important limitation:
Commercial aircraft typically fly near the upper troposphere/lower stratosphere, depending on the type of aircraft and flight conditions
Weather Forecasting
Q3. A weather department predicts a sharp fall in temperature accompanied by strong winds and heavy rainfall for the next 24 hours.
A school is planning an outdoor sports event on the same day.
Is this prediction related to weather or climate? Give two reasons why the school should consider this information while making its decision.
ANSWER:
It is about weather. It is a prediction of atmospheric conditions expected in the next 24 hours.
Short-term condition: Weather is the day-to-day or short-term state of the atmosphere, including temperature, rainfall, wind and humidity.
Climate is different Climate is the average pattern of weather over a long period of time, usually several decades.
The school should consider this information while making its decision because:
Safety of students:
Heavy rain and strong winds can cause unsafe conditions for students and staff at an outdoor event.
Event disruption or delay:
Rain and a sharp drop in temperature may make the sports ground unsuitable, and scheduled activities may be disrupted.
Risk in Decision-making:
The school should consult the forecast and reschedule or move the event indoors if needed.
Carbon Footprint
Q4. Two families live in the same city. Family A uses private vehicles for most journeys, keeps electrical appliances running unnecessarily, and frequently uses air conditioners. Family B uses public transport, switches off appliances when not required, and uses energy-efficient devices.
Which family is likely to have a lower carbon footprint? Explain three reasons based on their everyday activities.
ANSWER:
Family B is likely to have a smaller carbon footprint. This is because they are using fewer fossil fuels and less energy in their day-to-day activities.
Firstly, they are Using of Public Transport:
A rise in the use of public transport rather than private vehicles decreases fuel consumption and greenhouse-gas emissions per person.
Secondly, Conserving Energy:
Turning off electrical appliances when not in use, it reduces electricity consumption and related carbon emissions.
Thirdly, they use energy-efficient appliances:
Appliances that are efficient use less electricity to perform the same task.
The overall effect of these practices is to reduce the family’s contribution to greenhouse-gas emissions and climate change.
Climate Change and Local Environment
Q5. A coastal village has experienced increasingly irregular rainfall, more frequent heat waves, and gradual changes in the timing of seasonal activities over several decades. The villagers notice that these changes are affecting agriculture and water availability.
Why would it be inappropriate to describe these observations simply as changes in daily weather? Explain how they may indicate a broader climate change trend
ANSWER: It would be inappropriate to describe these observations simply as changes in daily weather because;
Not everyday weather:
Firstly, daily weather describes short-term atmospheric conditions occurring over hours or days.
Pattern over a long time period:
Secondly, when irregular rainfall and heat waves keep happening over decades, it is a long-term change in the climate pattern.
Changing seasons:
Thirdly, normal climate cycles may be shifting, based on the timing of seasonal activities.
Repeating effects:
Moreover, the lasting effects on agriculture and water availability suggest a continued trend rather than a one-time weather event.
Indication of climate change:
Lastly, these long-term changes in temperature, rainfall patterns, and extreme weather events might be an indication of a broader trend of climate change.
