Climates of India Class 7 Long Question Answer
Question 1.
Where is Mawsynrarn located, and why does it receive the highest rainfall in the world?
Answer:
Mawsynram is located in the East Khasi Hills district of Meghalaya, India. It holds the record for the highest annual rainfall in the world, receiving about 11,000 mm of rain. This is mainly due to its location and landscape. Even though the region is not influenced by a typical low-pressure system, Mawsynram lies on the windward side of the Khasi Hills, directly in the path of moisture-laden winds from the Bay of Bengal. When these winds hit the hills, they are forced to rise, moisture to cool, condense, and result in extreme rainfall.
Question 2.
How does climate cause disasters?
Answer:
Climate plays a crucial role in triggering natural disasters such as floods, land slides, cyclones, and forest fires. Heavy and continuous rainfall, often caused by changing wind patterns or monsoon shifts, can result in severe flooding, especially in coastal areas. In mountainous regions, excessive rain weak ens soil and rocks, causing landslides that damage homes, roads, and infrastructure. Cyclones are closely linked to climate factors like ocean temperatures and atmospheric pressure.
Warmer ocean waters provide the energy needed for cyclones to form and grow stronger, bringing destructive winds and heavy rain to coastal regions. Dry conditions increase the risk of forest fires, especially in states like Uttarakhand and Himachal Pradesh, where dry pine forests and strong winds allow fires to spread quickly. Climate change is causing these disasters to happen more often and become more dangerous, putting people and nature at risk.
Question 3.
What is resilience, and why is it important in disaster-prone areas?
Answer:
Resilience refers to the ability to recover quickly from difficulties or adapt to challenging situations. In disaster-prone are as, this quality is crucial as it helps communities cope with natural disasters like floods, cyclones, landslides, and forest fires. Strong infrastructure, early warning systems, and disaster preparedness plans play a key role in minimising damage and saving lives. Communities that adopt sustainable practices, such as planting trees to prevent soil erosion, building flood-resistant homes, and improving drainage systems, are better equipped to handle such challenges. By strengthening these measures, people can protect them selves, their homes, and their surroundings from the harmful impacts of disasters.
Climates of India Class 7 Source Based Questions
Mawsynram, located in Meghalaya, receives the highest average annual rainfall in the world, about 11,000 mm (which is the same as 11 meters!). (Don’t Miss Out. Page 55)
Question 1.
Why does Mawsynram receive the highest annual rainfall in the world?
Answer:
Mawsynram receives the highest annual rainfall because moisture-laden winds from Bay of Bengal move towards the north during the monsoon season. When these winds reach the Khasi hills, they are forced to rise, cool down and condense, leading to heavy rainfall. The combination of its location, monsoon winds and surrounding mountains contribute to the extremely high rainfall.
Question 2.
How does Khasi Hills influence the rainfall pattern in Mawsynram?
Answer:
The Khasi Hills play a crucial role in the rainfall pattern of Mawsynrarn. When the moisture-laden winds arrive, they are forced to ascend. As the air rises, it cools and condenses, resulting in the heavy rainfall. This orographic* effect is a key reason why Mawsynram experiences such high precipitation levels.
Question 3.
Despite not being in a low-pressure zone, why does Mawsynram still receive heavy rainfall?
Answer:
Although Mawsynram is not in a low pressure zone, it receives heavy rainfall due to its geographical location and the impact of monsoon winds.
Question 4.
What would happen to Mawsynram’s rainfall if the monsoon winds from Bay of Bengal changed direction?
Answer:
If the monsoon winds from the Bay of Bengal changed direction, Mawsynram would receive significantly less rainfall. Since its high rainfall is dependent on these winds carrying moisture to Khasi Hills, a shift in wind direction could reduce the amount of moisture reaching the region, leading to a drier climate.

Climates of India Class 7 Competency Based Questions
Question 1.
Will the climate of two areas at the same altitude be the same? Support your answer with a reason?
Answer:
No, the climate of two areas at the same altitude may not be the same. Other factors, such as latitude, proximity to water bodies, wind patterns and vegetation, also influence the climate. For example, an area near the coast may have a milder and more humid climate than an inland area at the same latitude may experience more extreme temperature variations over the years.
Question 2.
How does wind affect the climate of an area?
Answer:
Wind affects the climate of an area by influencing temperature, humidity and precipitation. Winds can carry warm or cold air from one region to another, affecting local temperatures. For example, coastal areas ex-perience milder climates due to sea breezes, while deserts may have extreme temperatures due to dry winds. Winds also transport moisture, leading to rainfall in some areas and dryness in others, depending on their direction and origin.
Climates of India Class 7 Skill Based Questions
Question 1.
Interpret the following data and explain how altitude affects climate:
| Location | Altitude (metres) | Average Temperature (°C) |
| City A | 200 | 25 |
| City B | 1500 | 15 |
Answer:
The data shows that City B, which is at higher altitude (1500m), has a lower average temperature (15°C) compared to City A (25°C) at lower altitude (200 metres). This supports the principle that temperature decreases with increasing altitude due lower air pressure and thinner atmospher which absorbs less heat.
Question 2.
How would the climate of a mountainous region differ from that of a nearby plain? Explain with reasons.
Answer:
A mountainous region generally has a cooler climate compared to a nearby plain due to higher altitude, where temperature decrease with elevation. Mountains also receive more precipitation as moist air rises, cools and condenses, leading to frequent rainfall or snowfall. In contrast, the plain experiences warmer temperatures and may have less rainfall, depending on other climatic factors like wind patterns and proximity to water bodies.
