NCERT Solutions for Class 9 Geography Chapter 4 FAQs
What are the reasons for climate in Class 9?
The controls affecting the climate of India are latitude, altitude, pressure and wind system, distance from the sea, ocean currents and relief features. (ii) The climate of India is strongly influenced by monsoon winds. Hence, it has a monsoon type of climate.
What is climate Class 9 short answer?
The climate refers to the sum total of weather conditions and variations over a large area for a long period of time.
Which factors affect climate?
The temperature characteristics of a region are influenced by natural factors such as latitude, elevation and the presence of ocean currents. The precipitation characteristics of a region are influenced by factors such as proximity to mountain ranges and prevailing winds.
What causes equable climate?
Equable climate is caused because they are situated close to or along the hence the influence of the sea has an effect on the temperature. The diurnal range of temperature is less hence it has a moderate or maritime climate. Therefore, the annual range in temperature is low.
Why are winds important?
Wind is a major factor in determining weather and climate. Wind carries heat, moisture, pollutants, and pollen to new areas. Many daily weather patterns depend on wind.

Q2. Answer the following questions briefly.
(i) What are the factors affecting the climate of India?
Answer:
The factors affecting the climate of India are
1. Latitude
2. Altitude
3. Pressure and Winds
(ii) Why does India have a monsoon type of climate?
Answer:
The climate of India is described as the ‘monsoon’ type. Monsoon refers to the seasonal reversal in the wind direction during a year.
The monsoon type of climate is characterised by a distinct seasonal pattern. The weather conditions greatly change from one season to the other. These changes are particularly noticeable in the interior parts of the country. The coastal areas do not experience much variation in temperature, though there is variation in the rainfall pattern.
Four main seasons can be identified in India – the cold weather season, the hot weather season, the advancing monsoon and the retreating monsoon with some regional variations.
The climate of India is strongly influenced by monsoon winds. The duration of the monsoon is between 100-120 days from early June to mid-September.
(iii) Which part of India does experience the highest diurnal range of temperature and why?
Answer:
The regions experiencing this phenomenon are in the northwestern part of India. The reason behind this effect is the Thar desert. Moreover, this region does not have an ocean to moderate the temperature.
(iv) Which winds account for rainfall along the Malabar Coast?
Answer:
Southwest monsoon winds are responsible for rainfall along the Malabar Coast.
(v) What are Jet streams, and how do they affect the climate of India?
Answer:
Jet Streams are a narrow belt of high altitude (above 12,000 m) westerly winds in the troposphere. Their speed varies from about 110 km/h in summer to about 184 km/h in winter. A number of separate jet streams have been identified.
The most constant is the mid-latitude and subtropical jet stream. They cause depression during the monsoon season.
(vi) Define monsoons. What do you understand by “break” in monsoon?
Answer:
Breaks in monsoon are related to the movement of the monsoon trough. For various reasons, the trough and its axis keep on moving northward or southward, which determines the spatial distribution of rainfall. When the axis of the monsoon trough lies over the plains, rainfall is good in these parts.
On the other hand, whenever the axis shifts closer to the Himalayas, there are longer dry spells in the plains, and widespread rain occurs in the mountainous catchment areas of the Himalayan rivers.
(vii) Why is the monsoon considered a unifying bond?
Answer:
The unifying influence of the monsoon on the Indian subcontinent is quite perceptible. The seasonal alteration of the wind systems and the associated weather conditions provide a rhythmic cycle of seasons.
Even the uncertainties of rain and uneven distribution are very much typical of the monsoons. The Indian landscape, its animal and plant life, its entire agricultural calendar and the life of the people (including their festivities) revolve around this phenomenon.
Year after year, the people of India, from north to south and from east to west, eagerly await the arrival of the monsoon. These monsoon winds bind the whole country by providing water to set agricultural activities in motion. The river valleys which carry this water also unite as a single river valley unit.
Q3. Why does the rainfall decrease from the east to the west in Northern India?
Answer:
As they move in that direction, the winds lose the moisture content. Hence, the reason for the reduction in rainfall.
Q4. Give reasons as to why.
(i) Seasonal reversal of wind direction takes place over the Indian subcontinent?
Answer:
1. Seasonal change in wind direction due to pressure difference.
2. El Nino plays a major role.
(ii) The bulk of rainfall in India is concentrated over a few months.
Answer:
Rainfall is dependent on the Southwest Monsoon winds; it rapidly progresses and covers large swathes of the country by July.
(iii) The Tamil Nadu coast receives winter rainfall.
Answer:
It is because of North-East monsoon winds.
(iv) The delta region of the eastern coast is frequently struck by cyclones.
Answer:
The Bay of Bengal faces frequent pressure changes.
(v) Parts of Rajasthan, Gujarat and the leeward side of the Western Ghats are drought-prone.
Answer:
Because they fall in the rain shadow region of the Aravali Mountains.
Q5. Describe the regional variations in the climatic conditions of India with the help of suitable examples
Answer:
India's climatic conditions show significant regional variations due to its diverse geography. In the northern region, the cold weather season starts in mid-November and lasts until February, with December and January being the coldest months. Temperatures generally decrease from south to north. For instance, Chennai on the eastern coast has a mild winter with average temperatures around 24°-25° Celsius, while the northern plains experience colder weather, with temperatures ranging between 10° and 15° Celsius. Frost is common in the north, and higher Himalayan regions see snowfall during this period.
As the summer season begins, regional temperature differences become more apparent. By March, the Deccan Plateau experiences temperatures around 38° Celsius, and by April, areas in Gujarat and Madhya Pradesh reach around 42° Celsius. In May, the northwestern parts of India frequently record temperatures as high as 45° Celsius, demonstrating the country’s vast climatic diversity.
Q6. Discuss the mechanisms of the monsoon.
Answer:
(a) The differential heating and cooling of land and water create a low pressure on the landmass of India while the seas around experience comparatively high pressure.
(b) The shift of the position of Inter Tropical Convergence Zone (ITCZ) in summer over the Ganga Plain. (This is the equatorial trough, normally positioned about 5°N of the equator. It is also known as the monsoon trough during the monsoon season.)
(c) The presence of the high-pressure area, east of Madagascar, approximately at 20°S over the Indian Ocean. The intensity and position of this high-pressure area affect the Indian Monsoon.
(d) The Tibetan Plateau gets intensely heated during summer, which results in strong vertical air currents and the formation of low pressure over the plateau at about 9 km above sea level.
(e) The movement of the westerly jet stream to the north of the Himalayas and the presence of the tropical easterly jet stream over the Indian peninsula during summer.
