Class 9 (Geography)

Chapter 6 (Population)

 

Notes

 

Population Overview

Population is considered a nation's most valuable asset, as individuals contribute to economic and societal development through their labor and expertise. The census of India provides comprehensive data on the total population and various demographic aspects.

Population Size and Distribution

Population Size: In March 2001, India's population stood at 1,028 million, comprising approximately 16.7% of the global population. Uttar Pradesh, with a population of 166 million, is the most populous state, accounting for 16% of the country's total population. Conversely, Sikkim has a population of about 0.5 million, while Lakshadweep houses only 60,000 individuals. Nearly half of India's population resides in five states: Uttar Pradesh, Maharashtra, Bihar, West Bengal, and Andhra Pradesh. Rajasthan, the largest state, comprises only 5.5% of the total population.

Population Density: Population density refers to the number of individuals per unit area. India is one of the world's most densely populated countries, with a density of 324 persons/sq km in 2001. West Bengal recorded the highest population density at 904 persons/sq km, while Arunachal Pradesh had the lowest at 13 persons/sq km. Factors such as terrain and climate influence population density, with flat plains experiencing higher densities compared to rugged landscapes.

Population Growth and Processes of Change

Population Growth: India's population has steadily increased from 361 million in 1951 to 1,028 million in 2001. The declining growth rate indicates efforts to control births and manage population growth effectively.

Processes of Change: Population change results from birth rate, death rate, and migration. Birth rate denotes live births per thousand persons annually, while death rate represents deaths per thousand individuals annually. Migration, whether internal or international, impacts population size and distribution.

Age Composition

Population age composition categorizes individuals into children (below 15 years), working-age (15–59 years), and aged (above 59 years). Each group plays a distinct role in the economy, with the working-age population contributing to the workforce.

Sex Ratio and Literacy Rates

Sex ratio indicates the number of females per 1000 males in the population. Literacy rates measure the proportion of literate individuals aged above 7 years. In 2001, India's literacy rate was 64.84%, with notable gender disparities.

Occupational Structure and Health

Occupational structure classifies individuals based on primary, secondary, and tertiary activities. India's predominantly agricultural workforce highlights its developing status. Health indicators, including access to safe drinking water and sanitation facilities, influence population well-being.

Adolescent Population and National Population Policy

Adolescents, aged 10–19 years, comprise one-fifth of India's population and require focused attention for proper nutrition and health care.

Notes

 

Factors Affecting India’s Climate:

  1. Latitude:
    • The Tropic of Cancer divides India into tropical (north) and subtropical (south) regions.
    • The northern parts, being closer to the Tropic of Cancer, experience colder climates, while the southern parts, farther away, tend to have warmer climates.
  2. Altitude:
    • India's diverse topography includes the towering Himalayan range in the north and low-lying coastal areas in the south.
    • The Himalayas, with their average height of about 6,000 meters, significantly influence the climate by blocking the penetration of cold air from Central Asia. This barrier effect leads to colder climates in regions adjacent to the Himalayas.
    • Conversely, the coastal areas, with altitudes as low as 30 meters, experience milder climates due to their proximity to the sea and lower elevation.
  3. Wind and Pressure:
    • India's climate is greatly influenced by wind and pressure systems, particularly the seasonal monsoons.
    • Northeasterly winds originating from subtropical high-pressure belts of the northern hemisphere play a crucial role in determining weather patterns in India.
    • The Coriolis effect, caused by the Earth's rotation, deflects these winds, leading to their circulation towards low-pressure belts and impacting regional climates.

Indian Monsoons: Arrival and Retreat:

  • Monsoon Period:
    • The Indian monsoon season typically spans from June to mid-September, lasting around 100 to 150 days.
    • During this period, India experiences significant and sustained rainfall, commonly referred to as the "burst of monsoon."
  • Arrival:
    • The onset of monsoon begins with the arrival of monsoon winds at the southern tip of the Indian peninsula in early June.
    • These winds then divide into two branches, namely the Arabian Sea branch and the Bay of Bengal branch.
    • Geographic features such as mountains influence the direction of monsoon winds, causing them to deflect and bring rainfall to various regions.
  • Monsoon:
    • The low-pressure system over the Gangetic plains attracts trade winds from the southern hemisphere, contributing to the onset of monsoon rains.
    • Regions like the windward side of the Western Ghats receive substantial rainfall, while rainshadow areas experience relatively lower precipitation due to geographical factors.
    • Notably, the northeastern parts of India receive significant rainfall during the monsoon season.

Chapter 3 (Drainage)

 

Notes

 

1. Drainage is the term used to describe the river system within a particular area. It refers to the network of rivers and streams that drain water from the land into larger bodies of water such as lakes, seas, or oceans. A drainage basin, also known as a river basin, encompasses the entire area drained by a single river system. A water divide, typically an elevated landform like a mountain or upland, separates adjacent drainage basins.

2. In India, there are two main river systems based on their origin: the Himalayan rivers and the Peninsular rivers. Himalayan rivers are characterized by their perennial flow, as they are fed by both rainwater and snowmelt throughout the year. These rivers create distinctive features such as meanders and oxbow lakes along their courses. On the other hand, Peninsular rivers are seasonal and primarily rely on rainfall, making them non-navigable for most of the year. They originate in the Western Ghats and flow towards the Bay of Bengal.

3. The Himalayan Rivers:

  • The major Himalayan rivers include the Indus, Ganga, and Brahmaputra.
  • The Indus River system originates in Tibet and flows through Ladakh into Pakistan before emptying into the Arabian Sea.
  • The Ganga River system, with its headwaters in the Gangotri Glacier, is joined by various tributaries like the Yamuna and Ghaghara before flowing into the Bay of Bengal via Bangladesh.
  • The Brahmaputra River system, originating in Tibet, enters India through Arunachal Pradesh and flows through Assam, forming riverine islands along its course.

Chapter 2 (Physical Features of India)

 

Notes

 

 

Physical Features of India:

Origins of Indian Landforms:

  • The Peninsular Plateau region was once part of Gondwana Land millions of years ago.
  • Landmass shifts and oceanic currents fragmented the land into pieces.
  • The northward movement of the Indo-Australian plate led to its collision with the Eurasian plate, resulting in the formation of the Himalayas.

Key Physical Features of India:

  • India's physical features can be broadly classified into six categories based on their physiographic structures.

The Himalayan Mountain Range:

  • The Himalayas, located in the northernmost part of India, are renowned for being the world's tallest and most rugged mountains.
  • Stretching over 2500 KM from Kashmir to Arunachal Pradesh, they form an arc.
  • The width of the Himalayan range varies from 400 Km to 150 KM and is divided into three main sections:
    • The Greater Himalayas with peaks towering up to 6000 meters.
    • The Lesser Himalayas with peaks reaching heights of about 4000 meters.
    • The Outer Himalayas, also known as the Shivalik Range.
  • Additionally, the Eastern Hills or Purvanchal are situated in North Bengal and the northernmost parts of northeastern states.

The Northern Plains:

  • These plains, situated at the foothills of the Himalayas, are irrigated by the major river systems of the Ganges, Indus, and Brahmaputra.
  • The fertile plains owe their richness to the extensive alluvial deposits brought down by these rivers.
  • The Northern Plains can be categorized into three sections:
    • The region of the Indus River and its tributaries in Pakistan.
    • The plains along the Ganges in states like Haryana, Bihar, Uttar Pradesh, and Jharkhand.
    • The Brahmaputra Plains in Assam and other northeastern states.

The Peninsular Plateau:

  • Formed from the geological movements of Gondwana Land, the Peninsular Plateau is the oldest landmass in India.
  • It is divided into:
    • The Central Highlands covering the Malwa Plateau north of the Narmada River.
    • The Deccan Plateau, triangular in shape and bordered by the Eastern and Western Ghats.
    • The Satpura mountain ranges in the northern part of the Deccan Plateau.
    • The Western Ghats, with peaks rising to 1600 meters, and the Eastern Ghats, reaching heights of about 600 meters.

The Indian Desert:

  • Located on the western edges of the Aravalli Hills, the Indian Desert comprises undulating sandy fields.
  • With minimal precipitation (around 150 mm per annum), it is considered the driest region in the country.
  • The desert region spans across Rajasthan and the northwestern parts of Gujarat.

The Coastal Plains:

  • India's coastal plains lie along the Arabian Sea and the Bay of Bengal.
  • The Western coast is divided into three segments: the Konkan (Mumbai – Goa), the Kannad Plain, and the Malabar coast.
  • The Eastern coast comprises the Northern Circar and the Coromandel Coast.
  • Large deltas, formed by rivers such as the Mahanadi, Godavari, Krishna, and Kaveri, are notable features.
  • Lake Chilika is a prominent feature on the eastern coast.

The Islands:

  • Two major groups of islands surround the Indian mainland.
  • The Lakshadweep islands, consisting mainly of coral formations, lie closer to the Malabar Coast.
  • The Andaman and Nicobar Islands, situated in the Bay of Bengal, are larger in size and renowned for their rich biodiversity.
  • The Andaman and Nicobar Islands, being closer to the equator, experience a tropical climate.

 

 

Important Question Answers

 

Question 1. What defines tectonic plates?

Answer: Tectonic plates refer to large fragments of the Earth's crust that have been torn apart due to rising currents.

Question 2. Which landmasses were part of the ancient Gondwana land?

Answer: South America, portions of Africa (including South Africa and Madagascar), parts of Asia (such as India, Arabia, and Malaya), Australia, and Antarctica were all components of the Gondwana land.

Question 3. Define the term "bhabar."

Answer: The bhabar is a narrow belt of plain covered with pebbles that runs along the foothills of the Shiwaliks from the Indus to the Teesta.

Question 4. List the three main divisions of the Himalayas from north to south.

Answer: The three major divisions of the Himalayas from north to south are the Great Himalayas (Himadri), the Middle Himalayas (Himachal), and the Outer Himalayas (Shivaliks).

Question 5. Which plateau is situated between the Aravali and Vindhyan ranges?

Answer: The Malwa plateau is located between the Aravali and Vindhyan Ranges.

Question 6. Identify the Indian island group formed primarily from coral.

 Answer: The Lakshadweep Islands constitute the Indian island group primarily formed from coral.

Question 7. Distinguish between Converging and diverging tectonic plates

Answer: When tectonic plates converge, they move towards each other, resulting in a collision or one plate sliding under the other. This process leads to the formation of folds in the crust.

On the other hand, when tectonic plates diverge, they move away from each other without colliding or crumbling. This movement creates fractures in the crust.

Question 8. Distinguish between Bhangar and Khadar.

Answer:  Bhangar refers to the older alluvium or aged soil, constituting the majority of the Northern Plains. It lies above the flood plains of rivers and exhibits a terrace-like feature, often containing calcareous deposits known as Kankar. However, it is less fertile compared to Khadar.

Khadar, on the other hand, represents the newer and younger deposits of flood plains, renewed annually. It is situated below Bhangar and is characterized by its higher fertility, making it more suitable for agricultural purposes.

Question 9. Distinguish between Western Ghats and Eastern Ghats

Answer:  The Western Ghats delineate the western boundary of the Deccan Plateau, whereas the Eastern Ghats mark its eastern edge. The Western Ghats form a continuous range, traversable only through passes, while the Eastern Ghats are discontinuous, irregular, and intersected by rivers flowing into the Bay of Bengal.

With an average elevation ranging from 900 to 1600 meters, the Western Ghats stand taller compared to the Eastern Ghats, which have an average elevation of around 600 meters. The Western Ghats serve as a source for many major rivers, unlike the Eastern Ghats, from which no significant river originates.

The Western Ghats predominantly experience orographic rainfall during the summer monsoons, resulting in a hot and moist climate. In contrast, the Eastern Ghats receive rainfall both in summer and winter, particularly through winter monsoons, though the amount is generally lower than that received by the western strip.

The soil in the Western Ghats is highly fertile, conducive to the cultivation of rice, spices, rubber, and fruits like coconuts and cashew nuts. Conversely, the soil in the Eastern Ghats is not as fertile as that in the Western Ghats, but it still supports the cultivation of crops such as rice, groundnuts, cotton, tobacco, and coconuts.

Question 10. Contrast the relief of the Himalayan region with that of the Peninsular plateau.

Answer: The Himalayan Region, characterized by its young fold mountains resulting from the uplift of strata formed by sedimentary rocks, contrasts with the Peninsular Plateau, which originated from igneous and metamorphic rocks following the fragmentation of Gondwanaland.

In terms of topography, the Himalayan Region features the loftiest mountains and deep valleys, often with I-shaped and U-shaped valleys. On the other hand, the Peninsular Plateau consists of broad and shallow valleys, along with rounded hills, including horsts, rift valleys, and troughs.

The Himalayan Region serves as the origin of perennial rivers, while the Peninsular Plateau is characterized by rainfed, seasonal rivers.

Geologically, the Himalayan Region is considered an unstable zone, whereas the Peninsular Plateau forms a stable zone.

Question 11: Discuss the Northern Plains of India.

Answer: The Northern Plains of India have been shaped by the alluvium deposited by mountain rivers, rendering the surface soil fertile for diverse crop cultivation. This facilitated the rise of the Indus River Valley Civilization. The fertile soil, coupled with favorable climatic conditions and consistent water supply from rivers, contributed to agricultural prosperity. Stretching over a distance of 3200 km between the mouths of the Indus and the Ganga-Brahmaputra, these plains vary in width from 300 to 150 km. The region encompasses the Indus river system in the west and the Ganga-Brahmaputra river system in the east. Notably, the latter forms the world's largest and fastest-growing delta. The Northern Plains are divided into four zones based on relief: Bhabhar, Tarai, Bangar, and Khadar.

Question 12: Briefly explain the following.

(i) The Indian Desert

Answer: The Indian Desert lies along the western margins of the Aravali Hills, characterized by undulating sandy plains dotted with sand dunes known as barchans. With rainfall averaging below 150 mm per year, this region experiences an arid climate with minimal vegetation. Temporary streams emerge during the rainy season but vanish into the sand due to insufficient water to reach the sea, with the Luni River being the notable exception.

(ii) The Central Highlands

Answer: The Central Highlands, situated north of the Narmada River and covering a significant portion of the Malwa plateau, form part of the peninsular plateau. Bounded by the Vindhyan range to the south and the Aravali range to the northwest, this region is drained by rivers like the Chambal, Sind, Betwa, and Ken, flowing southwest to northeast. The Central Highlands are wider in the west but narrower in the east, extending further as Bundelkhand and Baghelkhand to the east, eventually merging into the Chotanagpur plateau drained by the Damodar River.

(iii) The Island groups of India

Answer: India comprises two main island groups, namely Lakshadweep and Andaman and Nicobar Islands. Lakshadweep, located opposite the Kerala coast in the Arabian Sea, consists of numerous small coral islands known as atolls, characterized by their ring or horseshoe shape. In contrast, the Andaman and Nicobar Islands are larger and more widely scattered, with about 200 islands in the Andaman group and 19 islands in the Nicobar group.

Long Question Answers


Q1: Why is the difference between the durations of day and night hardly felt at Kanyakumari but not so in Kashmir?

The disparity in the lengths of day and night in Kanyakumari and Kashmir is predominantly influenced by their latitudinal positions. Kanyakumari, situated closer to the equator, experiences a relatively minor variation of about 45 minutes between the duration of day and night. In contrast, Kashmir, positioned farther from the equator, undergoes a significant contrast in the length of day and night, which can extend to approximately 3-5 hours.

Q2: What is a subcontinent? Name the countries that constitute the Indian subcontinent. How is India different from other countries of Asia?

  1. A subcontinent is a distinct geographical unit that stands out prominently from the rest of the region due to its large size, varied climates, and diverse relief.
  2. The countries comprising the Indian subcontinent are India at its core, Pakistan to the west, Nepal and China (Tibet) to the north, and Bhutan and Bangladesh to the east.
  3. India sets itself apart from other Asian countries concerning climate, vegetation, and culture.

Q3: India’s land routes have been important since ancient times. Explain.

India's connections with the outside world have persisted through the ages, with its land routes dating back much earlier than its maritime contacts. Various passes across the northern mountains have facilitated passage for ancient travelers, contributing to the exchange of ideas and commodities since antiquity. These routes, such as the Kyber and Bolan passes, have enabled the dissemination of cultural and intellectual concepts like the Upanishads, Ramayana, and Panchatantra stories, along with commodities like spices and muslin cloth. This exchange of goods and ideas has also influenced architectural styles, such as the adoption of Greek sculpture and West Asian architectural designs in various parts of India.

Q4: Why are Ahmedabad and Kolkata able to see the noon seen exactly overhead twice a year but not Delhi?

The sun's apparent movement within the tropics accounts for the phenomenon of the noon sun being directly overhead in certain locations. Places situated within the tropics witness the overhead sun twice a year. Both Ahmedabad and Kolkata are positioned south of the Tropic of Cancer, allowing them to experience the noon sun overhead twice annually. However, Delhi, located at 29°N latitude well to the north of the Tropic of Cancer, falls outside the tropics. Therefore, it never observes the noon sun directly overhead at any time of the year due to its position in the subtropical zone.

Q5: India occupies an important strategic position in South Asia. Discuss.

The Indian subcontinent occupies a crucial strategic position in South Asia due to its central location between East and West Asia. Its extension into the Indian Ocean connects it to both Europe and East Asia, making it a pivotal point along the trans-Indian Ocean routes. Additionally, its landmass connects India through land routes and mountain passes to various countries to the north, west, and east. Furthermore, the Deccan Peninsula's protrusion into the Indian Ocean enhances India's connectivity with West Asia, Africa, and Europe from the western coast, as well as Southeast and East Asia from the eastern coast.

Q6: Describe how the geographical features of India have fostered unity and homogeneity in Indian society.

India's geographical diversity has played a significant role in fostering unity and homogeneity within its society. The lofty northward-extending mountains create a natural barrier against potential intrusions, contributing to India's structural integrity. The southern peninsula, surrounded by seas and oceans, limits outside access to well-defended routes via sea or mountain passes. Additionally, the adoption of the standard meridian 82’30” as local time across India promotes uniformity. Rivers and their tributaries provide irrigation facilities nationwide, facilitating uniform development. Monsoons further foster unity through associated festivals and by fulfilling agricultural and domestic needs. This amalgamation of diverse geographical features has facilitated the adoption of new norms and values, promoting unity and homogeneity throughout India.
