2. Answer the following questions briefly.
(i). What are the controls affecting the climate of India?
Ans: The controls affecting the climate of India are temperature, atmospheric pressure, wind, humidity, and precipitation.
(ii). Why does India have a monsoon-type climate?
Ans: India comes in the Inter Tropical Convergence Zone (ITCZ) and together with factors such as El Nino, Coriolis Force, and Jet Streams, India gets a unique type of climate which is called the Monsoon type of climate in India.
(iii). Which part of India experiences the highest diurnal range of temperature and why?
Ans: The North-western part of India experiences the highest diurnal range of temperature as it receives the least amount of rainfall and also it is also away from the sea. So, the temperatures go to the extreme in this part of India.
(iv). Which winds account for rainfall along the Malabar coast?
Ans: The Malabar Coast gets most of the rainfall from the Southwest monsoon winds. Sometimes, although rare, this coast experiences cyclones as well which bring rainfall.
(v). Define monsoons. What do you understand by “break” in monsoon?
Ans: Monsoon break takes place due to the reversal of the wind direction. This includes a wet and dry spell during the rainy season during which very little rainfall takes place.
(vi). Why is the monsoon considered a unifying bond?
Ans: The monsoon in India influences almost all of the Indian Subcontinent and most of the activities take place based on these winds. The flora and fauna thrive in the subcontinent due to the monsoons and the crops are grown successfully based on the timings of the monsoons. Many festivals also take place based on the monsoon across India. So, the monsoon is called a unifying bond in India.
3. Why does the rainfall decrease from the east to the west in Northern India?
Ans: The rainfall in the eastern part of India occurs due to the Bay of Bengal branch of southwest monsoons. As the winds move from Bengal to the Gangetic plains, their moisture content decreases, and by the time they reach the Punjab region, they are almost dry. So, a decrease is seen in the amount of rainfall from east to west.
4. Give reasons as to why.
(i). Seasonal reversal of wind direction takes place over the Indian subcontinent.
Ans: The seasonal reversal of wind direction over the Indian subcontinent takes place due to pressure differences. The El Nino also plays a major role in the seasonal reversal of wind direction over the Indian subcontinent.
(ii). The bulk of rainfall in India is concentrated over a few months.
Ans: The monsoon season begins in India in June and by mid-July, it covers almost all of the Indian Subcontinent. The retreat of monsoons begins in September and not much rainfall occurs after that. Hence, in the Indian subcontinent, the rainfall is concentrated over a few months.
(iii). The Tamil Nadu coast receives winter rainfall.
Ans: The Tamil Nadu coast, known as the Coromandel Coast receives winter rainfall as the north-eastern winds, which are retreating monsoon winds take up moisture as they move over the Bay of Bengal during winters and pour the rains due to obstruction from the Eastern Ghats. Since the Coromandel Coast falls on the windward side, it gets winter rainfall.
(iv). The delta region of the eastern coast is frequently struck by cyclones.
Ans: The Bay of Bengal is the centre of various pressure changes so many cyclones develop in this region. Hence, the delta region of the Bay of Bengal witnessed multiple cyclones.
(v). Parts of Rajasthan, Gujarat, and the leeward side of the Western Ghats are drought-prone.
Ans: The parts of Rajasthan, Gujarat, and the leeward side of the Western Ghats are drought-prone as the Arabian Sea branch does not give enough rainfall in that region as it falls on the leeward side. The Aravalli mountains lie parallel to the direction of the winds so they do not force the winds to cause rains. Also, the Bay of Bengal branch becomes dry till it reaches Rajasthan.
5. Describe the regional variations in the climatic conditions of India with the help of suitable examples.
Ans: There is a huge regional variation in the climatic conditions of India. The Temperature and Precipitation vary not only from place to place but also from season to season.
In summer, the temperature goes up to 50°C in certain parts of Rajasthan but it barely crosses 20°C in Pahalgam in Kashmir region.
In winter, the night temperature in the Dras sector of Kashmir is below the freezing point of around -45°C but in Thiruvananthapuram, Kerala it hardly goes below 20°C.
In the Andaman and Nicobar Islands, the difference between day and night temperatures is barely 7° – 8°C.
The coastal areas experience less contrast in the temperature, whereas the seasonal contrasts are more in the interior of the country.
There is a decrease in rainfall generally from east to west in the northern plains.
Most parts of India get rainfall from June to August - September, whereas the Coromandel Coast gets rainfall in the winter season. Odisha gets rainfall from cyclones too.
6. Give an account of weather conditions and characteristics of the cold season.
Ans: The following are the features of the cold season in India:
The winter season begins in mid-November and continues till February in northern India.
December and January are the coldest months in the northern part of India which consists of Punjab, Delhi, Himachal Pradesh, etc.
The average temperature ranges between 10°-15°C in the northern plains, while it ranges around 24°-25°C in Southern India.
The northeast trade winds prevail over the entire country in this period. As these winds blow from land to sea, most parts of the country experience a dry climate.
The weather is usually marked by clear skies, low temperatures, low humidity, and weak variable winds.
The inflow of cyclonic disturbances from the west and the northwest is a characteristic feature of the cold weather over the northern plains of India.
These low-pressure systems originate over the Mediterranean Sea and Western Asia and move into India. They cause winter rains over the northwestern plains and snowfall in the mountains.
The winter rainfall is in small amounts but is very important for the rabi crops which are harvested in March - April.
The peninsular region does not get a well-defined winter because of the moderating influence of the sea and its location in the Torrid Zone.
7. Give the characteristics and effects of the monsoon rainfall in India.
Ans: The characteristics of the monsoon rainfall in India are:
The duration of the monsoon varies from 100 to 120 days which is from early June to mid-September.
Around the time of its arrival, the normal rainfall increases suddenly and continues regularly for several days. This is also called the ‘burst’ of the monsoons.
The monsoons are distinguished from the pre-monsoon showers because of their increase in rainfall amount and regularity.
The monsoon arrives at the southern tip of the Indian Peninsular generally by the first week of June.
The rainfall is unevenly distributed across the country. The effects of the monsoon rainfall in India:
The agriculture in India largely depends on Indian monsoons for water. Late, low, or excessive rains have a highly negative impact on crops.
Due to uneven distribution of rainfall across the country, few places are drought-prone such as Marathwada and Vidarbha and few are flood-prone such as Assam.
The monsoon provides India with a diverse climatic pattern.
Map Skills: On an outline map of India, show the following.
i. Areas receiving rainfall over 400 cm.
ii. Areas receiving less than 20 cm of rainfall.
iii. The direction of the southwest monsoon over India.

FAQs on NCERT Solutions for Class 9 Social Science Chapter 4 Climate
1. Are climate and weather the same thing in Geography?
No, climate and weather are two different concepts. Climate refers to the average weather conditions over a very long period (typically over 30 years), while weather describes the atmospheric conditions at a specific place and time.
This is a common point of confusion because we often discuss daily weather when talking about a place's climate. However, they operate on vastly different timescales.
For example, a rainy day in Delhi is its weather. But the fact that Delhi experiences hot, dry summers and cold winters is its climate. The climate is an aggregate of many years of weather data.
A simple rule to remember is: Climate is what you expect, and weather is what you get. Understanding this difference is key for many climate class 9 questions and answers.
In short, climate is a long-term pattern, whereas weather is a short-term event.
2. Do the Climate Class 9 NCERT Solutions PDF only contain final answers?
No, a high-quality climate class 9 NCERT Solutions PDF provides detailed, step-by-step explanations, not just the final answers. The goal is to show you *how* to arrive at the correct conclusion based on the NCERT textbook.
The misconception arises from thinking of solutions as simple cheat sheets. In reality, they are learning tools designed to clarify reasoning and improve answer-writing skills.
For instance, for a question on the factors affecting India's climate, the solutions won't just list 'Latitude' and 'Altitude'. They will explain *why* latitude causes temperature variations from south to north and *how* the Himalayas act as a climatic divide, blocking cold winds.
This structured approach helps you build strong foundational knowledge for your exams. The free PDF format also allows for easy offline access and practice anytime.
3. Is the 'Loo' just any hot wind during the Indian summer?
No, the Loo is a specific type of strong, gusty, hot, and dry wind that blows during the daytime over the north and northwestern parts of India in the summer. It's not a generic term for all hot winds and has distinct geographical and seasonal characteristics.
4. For my Class 9 SST exam, is it correct to say the monsoon is just continuous rain?
No, the Indian monsoon is not a period of continuous rain but is characterized by wet spells interspersed with 'breaks' or dry spells. These breaks in rainfall are a distinct feature of the monsoon season.
Students often oversimplify the monsoon as a single, long rainy season. However, its pulsating nature is a critical concept in the chapter on Climate.
For example, the monsoon trough's movement determines the rainfall pattern. When the trough lies over the plains, there is good rainfall. When it shifts closer to the Himalayas, the plains experience dry spells, while the mountain catchment areas receive widespread rain.
Understanding this pulsating nature is essential for correctly answering many class 9 social science chapter 4 question answers. It explains why rainfall varies in intensity and duration throughout the season.
5. Does using NCERT solutions mean I can skip reading the textbook?
Absolutely not. NCERT Solutions are designed to supplement and clarify the textbook, not replace it. The textbook provides the core concepts and context, while solutions help you understand how to apply those concepts to answer questions effectively. Relying only on solutions creates knowledge gaps.
6. Do Western Disturbances only bring bad weather to India?
No, Western Disturbances are actually beneficial for India's agriculture, especially during the winter. These weather systems originate over the Mediterranean Sea and bring much-needed winter rain to the plains and snowfall in the mountains.
The term 'disturbance' often has a negative connotation, leading to the myth that they are solely destructive. In meteorology, it simply refers to a change in the normal weather pattern.
This winter precipitation is locally known as 'mahawat' and is of immense importance for the cultivation of rabi crops, such as wheat, which is a staple food in northern India. The snowfall in the Himalayas also replenishes glaciers, ensuring a perennial water supply in rivers during the summer.
Therefore, these disturbances play a vital role in the region's ecological and economic stability, a key point in SST geography.
7. Are the NCERT Solutions for Class 9 Social Science Chapter 4 only for the final exercise questions?
No, the complete NCERT Solution Class 9 Social Science Chapter 4 covers all questions, including the in-text questions found within the chapter and the main exercises at the end. This ensures you can check your understanding as you progress through the chapter's concepts.
8. Does El Niño always cause a weak monsoon and drought in India?
An El Niño event is strongly linked to weaker monsoons and drought conditions in India, but it is not a guaranteed outcome every time. It is a complex phenomenon, and while the correlation is high, other atmospheric factors can sometimes moderate its impact.
This myth stems from the frequent news reports linking El Niño to poor rainfall. While it often leads to warmer sea surface temperatures in the Pacific, affecting wind and rain patterns globally, the connection is one of probability, not certainty.
For instance, some El Niño years have seen near-normal monsoon rainfall in India because other regional factors, like a positive Indian Ocean Dipole (IOD), counteracted its negative effect. The NCERT textbook highlights it as a key influencing factor, not an absolute determinant.
Think of it as a major influence that significantly increases the chances of a poor monsoon, but not a definite forecast. This nuance is crucial for higher-level answers.
9. Is downloading a Free PDF of the solutions complicated?
No, accessing the Free PDF for NCERT solutions on platforms like Vedantu is a straightforward process. It typically involves a simple, one-click download, allowing students to save the material directly to their devices for offline study without any complex steps or fees.
10. Are NCERT solutions just a way to get homework done quickly?
While they can help with homework, using NCERT Solutions is primarily a tool for deeper conceptual understanding and improving answer-writing skills. Simply copying answers for homework is a misuse that hinders learning.
The myth is that solutions are a shortcut. The correct approach is to attempt the climate questions and answers class 9 on your own first, then use the solutions to verify your answer, understand the ideal structure, and identify any gaps in your knowledge.
For example, you might write a correct but incomplete answer about the monsoon's withdrawal. The solutions will show you how to structure it chronologically, from north-west India in September to the rest of the country by early December, including all key details from the NCERT book.
Used correctly, they guide you from basic knowledge to a well-structured, complete answer, which is essential for scoring well in SST exams.
Think of solutions as a guide for self-assessment, not just a homework tool.
11. Is 'October Heat' just a normal warm feeling as summer ends?
No, 'October Heat' is a distinct weather phenomenon in India, characterized by a rise in temperature and oppressive humidity during the monsoon's retreat. It's not just lingering warmth; it's caused by clear skies and high moisture, making conditions quite uncomfortable.
