CBSE Class 7 Social Science Chapter 03 Climates Of India MCQs Set 03

Answer: (B) Seasonal winds blowing over a wide stretch of the Indian Ocean and nearby regions like Australia, Africa and South Asia

Explanation:
Strictly speaking, mausim (the Arabic root of 'monsoon') means 'season', and the chapter clarifies that the term properly describes seasonal winds across a large Indian Ocean region touching Australia, Africa and South Asia, not just India's rains.

Answer: (B) By noticing fish that usually stay underwater rising to the surface

Explanation:
The chapter mentions this as an example of traditional ecological knowledge passed down through generations. When fish that normally remain submerged start appearing at the surface, Konkan fishermen take it as a sign that the monsoon is near.

Answer: (A) Meghamalhar and amruthavarshini

Explanation:
Meghamalhar and amruthavarshini are named as ragas from Hindustani and Carnatic traditions that draw inspiration from the rains, showing how deeply the monsoon has shaped Indian art and culture.

Answer: (B) Masses of water droplets, ice crystals, or a mixture of both, suspended in the air

Explanation:
Clouds are not simply white lumps of air but collections of suspended water droplets and ice crystals, sometimes a mix of both, that form when moist air rises and cools.

Answer: (B) 12

Explanation:
The chapter notes that NDRF battalions are spread across 12 locations in India, allowing them to respond quickly to disasters such as cyclones, floods and landslides.

Answer: (B) About 6,000

Explanation:
The chapter records that around 6,000 people, a large number of them pilgrims visiting the Kedarnath temple, died when continuous heavy rain triggered a glacial burst and subsequent landslides in Uttarakhand.

Answer: (B) Earthquakes and volcanic activity

Explanation:
A landslide is described as a sudden collapse of rock, soil or debris that can be set off by earthquakes or volcanic activity, in addition to intense rain during the monsoon.

Answer: (A) Himachal Pradesh, Uttarakhand, Sikkim and Arunachal Pradesh

Explanation:
These hilly, mountainous states, along with the Western Ghats, are named as landslide-prone areas because of their steep terrain and frequent heavy monsoon rain; the other options list states associated with heat waves or floods instead.

Answer: (B) Carelessness on the part of people

Explanation:
While dry weather, drought and strong winds fuel forest fires, the chapter also points out that careless human behaviour is a frequent trigger of these blazes.

Answer: (B) Harm to wildlife, degraded ecosystems, poor air quality, and displaced communities

Explanation:
• Wildlife populations suffer direct harm
• The surrounding ecosystem becomes degraded
• Air quality worsens from smoke
• Local communities are sometimes forced to relocate
Together these show the chapter's point that forest fires carry both environmental and economic costs.

Answer: (B) India's cultural life is closely tied to seasonal and agricultural rhythms shaped by climate

Explanation:
By connecting these harvest and seasonal celebrations to the surrounding discussion of monsoons and agriculture, the chapter is illustrating how deeply climate patterns are woven into India's festivals and everyday cultural life.

Answer: (B) Because they reflect valuable local wisdom built up through careful long-term observation of nature

Explanation:
The chapter frames such knowledge, gathered over generations by people observing nature closely, as a form of cultural heritage rather than a replacement for modern science.

Answer: (A) A glacier melts rapidly or heavy rain falls, water builds up behind a rock-ice barrier, pressure increases, and the barrier eventually breaks

Explanation:
Glacial lakes are held back by natural barriers of rock and ice; when glaciers melt too quickly or heavy rain adds extra water, pressure builds until the barrier gives way, unleashing a sudden and destructive flood.

Answer: (A) What are the monsoons and how are they formed?

Explanation:
The introductory page lists five guiding questions, including one asking what monsoons are and how they form. The other options touch on themes not raised in that opening list.

Answer: (A) Vasanta Panchami

Explanation:
Vasanta Panchami is linked to vasanta, the spring ritu, showing how specific rituals and festivals correspond to the six traditional seasons. The other events named have no seasonal or ritu connection in the chapter.

Answer: (A) Because a portion of these winds passes over the Bay of Bengal and picks up moisture before reaching land

Explanation:
The chapter explains that although the northeast monsoon winds are basically dry, the part of them that travels over the Bay of Bengal gathers moisture, producing rainfall in parts of east and south India during winter.

Answer: (A) A set of seasonal winds affecting a wide area of the Indian Ocean region, including Australia, Africa and South Asia

Explanation:
The word comes from mausim, meaning 'season', and technically refers to seasonal wind patterns over a large stretch of the Indian Ocean and surrounding lands—not just the rains that fall on India.

Answer: (A) Enclosed valleys and urban heat islands

Explanation:
• Enclosed valleys and certain forests are cited as areas with their own localised climate patterns
• Urban heat islands, where concrete traps heat, are given as another example
• Both differ from the climate of the surrounding region, which is the defining feature of a microclimate

Answer: (A) Vapour turning back into liquid water droplets

Explanation:
As moist ocean air moves over the heated landmass, the water vapour it carries changes into liquid droplets, which then fall as rain—this change of state is what 'condense' refers to here.

Answer: (A) Land heats up and cools down faster than the ocean

Explanation:
This single fact—that land responds to heating and cooling more quickly than water—creates the pressure differences that drive winds toward the land in summer and away from it in winter, forming the basis of the whole monsoon system.

Answer: (A) Because many industrial processes rely on predictable weather and a steady water supply

Explanation:
Beyond agriculture, the chapter notes that industrial activity often needs consistent weather conditions and reliable access to water, so disruptions in the monsoon can ripple through to industrial output as well.

Answer: (A) They often conflict with the drive for economic growth and greater consumption

Explanation:
Steps such as cutting emissions or promoting sustainable living frequently clash with the broader push for economic expansion and rising consumption, a tension the chapter openly acknowledges rather than resolves.

Answer: (A) Industry, transportation and agriculture

Explanation:
The chapter attributes the rapid build-up of greenhouse gases mainly to modern industry, transport and agricultural practices, which together have released far more of these gases than natural processes ever did over comparable timescales.

Answer: (A) Develop unique methods to collect and store water

Explanation:
With extremely hot days, cool nights and very little rain, communities in the Thar Desert had to innovate special techniques for gathering and conserving scarce water, unlike the rice-and-spice farming seen in wetter coastal regions.

Answer: (A) India's varied geography, including mountains, deserts, plateaus and coastlines, shapes distinct local climates

Explanation:
The chapter's closing summary ties together its earlier discussion of latitude, altitude, coastal proximity, wind and topography to show that India's uneven landscape is what produces such a wide range of climates within one country.
