Question: In the context of the chapter, what does 'forecast' mean when applied to weather?
A. To measure the current temperature precisely
B. To record data using an automated station
C. To predict or determine weather conditions in advance
D. To convert a Celsius reading into Fahrenheit
Show Answer & Explanation

Answer: (C) To predict or determine weather conditions in advance

Explanation:

Question: How does the chapter define the term 'atmosphere' in relation to Earth?
A. The solid crust that surrounds Earth's core
B. The layer of gases surrounding the planet, which we call air
C. The layer of water bodies covering Earth's surface
D. The magnetic field protecting Earth from the sun
Show Answer & Explanation

Answer: (B) The layer of gases surrounding the planet, which we call air

Explanation:
The text explains that some planets are surrounded by a layer of gases, and on Earth these gases are simply called air — together forming the atmosphere.

Question: The chapter mentions that coconut oil turns solid in winter. What point does this example help illustrate?
A. Everyday changes in ordinary substances can hint at temperature without using instruments
B. Coconut oil is unsuitable for use in cold climates
C. Humidity levels rise sharply during winter months
D. Atmospheric pressure affects the texture of cooking oils
Show Answer & Explanation

Answer: (A) Everyday changes in ordinary substances can hint at temperature without using instruments

Explanation:
• The chapter lists common household observations, like curd setting slowly or oil solidifying, alongside snow melting and clouds forming.
• These are meant to show how people can sense temperature changes through familiar signs, even before checking a thermometer.

Question: Why does water tend to evaporate slowly on a rainy day, as explained in the chapter?
A. Because atmospheric pressure is unusually high on rainy days
B. Because the air is already carrying a lot of moisture, leaving little room for more evaporation
C. Because temperatures typically drop below freezing during rain
D. Because wind speed increases dramatically during rainfall
Show Answer & Explanation

Answer: (B) Because the air is already carrying a lot of moisture, leaving little room for more evaporation

Explanation:
When humidity is already high, the air is close to saturated with water vapour, so it cannot absorb much more moisture, which slows down evaporation.

Question: Roughly how high above the ground does the troposphere extend, according to the chapter?
A. 1 to 5 kilometres
B. 6 to 18 kilometres
C. 20 to 30 kilometres
D. 50 to 100 kilometres
Show Answer & Explanation

Answer: (B) 6 to 18 kilometres

Explanation:
This is the layer where humans, plants and animals live and where nearly all weather occurs, stretching from 6 to 18 kilometres depending on location.

Question: The two 'Big Questions' at the start of the chapter mainly guide readers to think about which pair of ideas?
A. The history of meteorology and its founders
B. Comparing weather patterns across different countries
C. Measuring and monitoring weather, and using predictions to prepare for extreme events
D. The chemical composition of atmospheric gases
Show Answer & Explanation

Answer: (C) Measuring and monitoring weather, and using predictions to prepare for extreme events

Explanation:
The opening questions frame the entire chapter around two themes: how weather can be tracked using instruments, and how forecasts help people get ready for things like storms, drought or heat waves.

Question: Why might the chapter open with Marcel Proust's line about a change in weather recreating the world and oneself anew?
A. To prove that weather cannot be scientifically measured
B. To introduce the idea that weather deeply shapes how we experience and respond to our surroundings
C. To criticise modern weather forecasting methods
D. To explain the historical origins of the word 'weather'
Show Answer & Explanation

Answer: (B) To introduce the idea that weather deeply shapes how we experience and respond to our surroundings

Explanation:
The quote sets a reflective tone before the chapter turns practical, reminding readers that something as ordinary as a shift in weather can change our mood, choices and daily routines — which is exactly why understanding it matters.

Question: The chapter suggests that Kochi is likely to have higher humidity than Jaipur mainly because of which factor?
A. Kochi receives far less rainfall annually
B. Kochi is located near the sea, while Jaipur lies inland
C. Jaipur sits at a much higher altitude than Kochi
D. Kochi experiences cooler temperatures throughout the year
Show Answer & Explanation

Answer: (B) Kochi is located near the sea, while Jaipur lies inland

Explanation:
Coastal locations tend to have more water vapour in the air, which is why the chapter uses Kochi's nearness to the sea as a likely reason for its higher humidity compared to inland Jaipur.

Question: As used in the chapter, what does the term 'statistics' mean?
A. A method of predicting cyclones using satellite images
B. The practice of collecting and analysing data to notice patterns or make predictions
C. A unit for measuring atmospheric pressure
D. An instrument used to record wind speed
Show Answer & Explanation

Answer: (B) The practice of collecting and analysing data to notice patterns or make predictions

Explanation:
The glossary describes statistics as gathering and studying information so that patterns can be detected or future events, such as temperature trends, can be anticipated.

Question: When rain falls into a rain gauge, in what order does the water travel before a reading can be taken?
A. It collects first in the cylinder, then rises up through the funnel
B. It falls directly onto the measuring scale and pools beneath it
C. It passes through the collecting funnel and gathers in the measuring cylinder, where the scale shows its depth
D. It evaporates inside the funnel before condensing in the cylinder
Show Answer & Explanation

Answer: (C) It passes through the collecting funnel and gathers in the measuring cylinder, where the scale shows its depth

Explanation:
• Rainwater first enters through the collecting funnel at the top of the gauge.
• It then drains down into the narrow measuring cylinder below.
• The scale marked on the cylinder is read to note the depth of water collected, which gives the rainfall figure.

Question: How does the chapter describe 'hail'?
A. A gentle drizzle common in coastal regions
B. Small hard balls of ice falling from the sky like rain
C. Frozen dew that forms on grass overnight
D. Water vapour that condenses into visible clouds
Show Answer & Explanation

Answer: (B) Small hard balls of ice falling from the sky like rain

Explanation:
Hail is defined in the glossary as small, hard ice pellets that fall from the sky in a manner similar to rain, distinguishing it from sleet, which is partly frozen rain.

Question: Why does the chapter stress that accurate weather prediction has become especially important in recent times?
A. Because thermometers were only invented very recently
B. Because climate change is making extreme weather such as droughts and cyclones more frequent
C. Because fewer people now observe traditional signs like ants or frogs
D. Because atmospheric pressure has risen everywhere on Earth
Show Answer & Explanation

Answer: (B) Because climate change is making extreme weather such as droughts and cyclones more frequent

Explanation:
The text links the growing need for precise forecasting directly to climate change, which is causing extreme weather events to occur more often, making early warnings essential for safety and planning.

Question: What is the main advantage of setting up a weather station, as described in the chapter?
A. It removes the need for meteorologists entirely
B. It brings all the different measuring instruments together in one place, making regular readings easier for forecasting
C. It only functions during storms and cyclones
D. It replaces the need for traditional nature-based weather signs
Show Answer & Explanation

Answer: (B) It brings all the different measuring instruments together in one place, making regular readings easier for forecasting

Explanation:
Rather than using each instrument separately, a weather station combines them so readings can be taken at regular intervals — this consolidated data is what feeds into mapping and forecasting the weather.

Question: The picture of snow melting quickly in warm conditions is used in the chapter mainly to show what?
A. That snow only ever falls in mountainous regions
B. That everyday visible changes can hint at rising temperature even without a thermometer
C. That precipitation and temperature are unrelated to each other
D. That humidity always increases whenever snow melts
Show Answer & Explanation

Answer: (B) That everyday visible changes can hint at rising temperature even without a thermometer

Explanation:
Like the examples of coconut oil solidifying or curd setting slowly, quickly melting snow is presented as a simple, observable clue people can use to sense warmer weather without needing an instrument.

Question: In what unit do barometers typically display atmospheric pressure readings, as explained in the chapter?
A. Degrees Celsius
B. Millimetres
C. Millibar
D. Kilometres per hour
Show Answer & Explanation

Answer: (C) Millibar

Explanation:
The chapter states that barometers usually show pressure in millibars, abbreviated mb, with normal sea-coast pressure around 1013 mb and anything below 1000 mb signalling a depression.

Question: Jyotsna checks the forecast for her June school trip to Mumbai and sees a prediction of 29°C with 84% humidity. Based on the chapter's explanation of humidity, what would be sensible advice for her packing?
A. Pack heavy woollens since 84% humidity means very cold air
B. Pack light, breathable clothes because high humidity combined with warmth will make the air feel sticky and uncomfortable
C. Pack only rain gear since humidity always means snowfall
D. Pack winter clothes because humidity above 80% always signals falling temperatures
Show Answer & Explanation

Answer: (B) Pack light, breathable clothes because high humidity combined with warmth will make the air feel sticky and uncomfortable

Explanation:
High relative humidity slows evaporation, so sweat does not dry easily and the air feels muggy even at moderate temperatures; light, breathable clothing suits such conditions far better than heavy or winter wear.

Question: The chapter introduces a term for the systematic scientific study of weather that forms the basis of forecasting. What is this field called?
A. Climatology
B. Meteorology
C. Hydrology
D. Seismology
Show Answer & Explanation

Answer: (B) Meteorology

Explanation:
Meteorology is defined in the chapter's glossary box as the organised study of weather and how it changes, and this study underlies all weather forecasting work.

Question: Why does the chapter say that digital thermometers are increasingly favoured over traditional liquid-filled ones?
A. They never need to be replaced
B. They are cheaper to manufacture
C. They give more accurate readings and can store more data
D. They work without any power source
Show Answer & Explanation

Answer: (C) They give more accurate readings and can store more data

Explanation:
Coloured-liquid thermometers rely on expansion to show temperature, but the text notes that digital versions are gaining preference simply because they offer greater precision and can record additional data.

Question: The chapter gives an example linking two temperature scales. According to it, 15 degrees Celsius equals which Fahrenheit value?
A. 50°F
B. 59°F
C. 68°F
D. 77°F
Show Answer & Explanation

Answer: (B) 59°F

Explanation:
The text directly gives this conversion as an example: a cool 15°C reading corresponds to 59°F on the Fahrenheit scale.

Question: In the 'layered cake' comparison used to describe Earth's atmosphere, which layer lies directly above the troposphere?
A. Ozone hole
B. Mesosphere
C. Stratosphere
D. Ionosphere
Show Answer & Explanation

Answer: (C) Stratosphere

Explanation:
The diagram in the chapter places the stratosphere just above the troposphere, separated by the tropopause, with the ozone layer sitting within this upper region.

Question: Towards the end of the chapter, examples are given of situations where one weather element becomes especially dominant, such as wind during a 'loo' or pressure during a cyclone. What point is this section mainly making?
A. That only wind and pressure matter for forecasting
B. That the five elements of weather never interact with each other
C. That depending on the season or event, a particular weather element can stand out as most significant
D. That humidity is always the most important element regardless of season
Show Answer & Explanation

Answer: (C) That depending on the season or event, a particular weather element can stand out as most significant

Explanation:
By listing rainfall in July, temperature extremes in May and December, pressure changes during cyclones, and wind during a loo, the chapter shows that while all five elements together define weather, one of them often takes centre stage depending on the situation.

Question: As mentioned in the chapter, what is a 'loo'?
A. A type of rain gauge used in northern India
B. Strong, hot and dusty winds that blow across north India during summer
C. A traditional method farmers use to predict monsoon arrival
D. An instrument that measures wind direction near airports
Show Answer & Explanation

Answer: (B) Strong, hot and dusty winds that blow across north India during summer

Explanation:
The chapter explains the loo as the hot, dust-laden summer winds of north India, citing it as an example of wind being the dominant weather element in certain seasons.

Question: According to the relative humidity ranges given in the chapter, into which bracket would dry weather typically fall?
A. 0% to 10%
B. 20% to 40%
C. 60% to 80%
D. 90% to 100%
Show Answer & Explanation

Answer: (B) 20% to 40%

Explanation:
The text notes that dry conditions generally show relative humidity between 20% and 40%, while humid weather usually ranges from 60% to 80%.

Question: If Delhi's humidity is 52% and Kochi's is 84% at the same temperature, what does the chapter's explanation suggest about drying wet clothes in these two cities?
A. Clothes dry equally fast in both cities regardless of humidity
B. Clothes dry faster in Kochi because higher humidity speeds up evaporation
C. Clothes dry faster in Delhi because lower humidity allows quicker evaporation
D. Drying speed depends only on wind, not humidity
Show Answer & Explanation

Answer: (C) Clothes dry faster in Delhi because lower humidity allows quicker evaporation

Explanation:
• Higher humidity means the air already holds more water vapour.
• This slows down evaporation, as noted in the chapter's science recap.
• With lower humidity, Delhi's air can absorb moisture from wet clothes more readily, so they dry faster there than in humid Kochi.
