1. what was the silk route what was its importance in the ancient times and also in the present times?
Silk Route was an ancient trading route that existed almost 5000 years ago. It emanated from China and passed through India and finally ended in Central Asia and Europe. This was a route through which India and China were able to trade with countries of Europe and North Central Asia. Through the Silk Route fine silk, paper, muslin, indigo, spices, condiments, were exported from India and China in return for bullion (gold and precious jewels). Bulk of the riches of India and China in the ancient time owe their earnings made through the export of commodities by the traders passing through the silk route.
The Silk Route continues to remain important in the present day times as China is trying to revive this Silk route by developing roads, and rapid transit trains along the ancient silk route to bolster its trade with the European and Central Asian countries. However it has also become a bone of contention as China tends to claim authority over the entire land over the land over which the rapid trade corridor is constructed.
2. What is a subcontinent ? Explain using examples
A subcontinent is a part of a bigger landmass but which has its own identity in terms of history, culture etc and which is also separated from the bigger landmass through a landform.
For example, the Indian subcontinent includes India, Pakistan, Bangladesh, Nepal, Bhutan, Maldives and Sri Lanka. This part of Asia, now constituting South Asia is separated from the rest of Asia by the Himalayas and also is culturally and historically different from the rest of Asia. The term Indian Sub-continent thus gives a unique identity and a sense of unity among the regions of South Asia.
3. What is a Peninsula ? Explain using examples
A peninsula is that landmass which is surrounded by water on three sides and is attached to a bigger land on the 4th side.
For example the part of India below the Tropic of Cancer forms a Peninsula as it is surrounded by the Indian Ocean on three sides but is attached to the Asian landmass on the Northern side.
Similarly, the Southern Cone (the southern part of Latin America comprising of Chile, Paraguay, Uruguay, Argentina) is also a Peninsular region.

(i) What is bhabar?
(ii) Name the three major divisions of the Himalayas from north to south.
(iii) Which plateau lies between the Aravali and the Vindhyan ranges?
(iv) Name the island group of India having coral origin.
(i) Bhabar is a term used to describe a narrow belt of land located at the foothills of the Himalayas. It is a part of Northern Plains and is characterized by the deposition of pebbles and coarse sediments brought down by rivers flowing from the mountains. The bhabar belt is typically around 8 to 16 kilometers in width and runs parallel to the slopes of the Shiwalik mountain range.
One of the distinctive features of the bhabar region is that many streams and rivers disappear underground in this belt due to the porous nature of the sediments. South of the bhabar belt lies a wet, swampy, and marshy region known as the terai, which was originally a densely forested area rich in wildlife.
The bhabar region has been historically significant for agriculture and settlement, as the fertile soil and water sources from the rivers have supported human habitation and cultivation in the Northern Plains of India.
(ii) The three major divisions of the Himalayas from north to south are:
Himadri: Also known as the Great Himalayas, this northernmost division consists of the highest peaks and ranges, including Mount Everest and K2. The Himadri region is characterized by snow-capped peaks, glaciers, and deep valleys.
Himachal: The middle division of the Himalayas, known as the Lesser Himalayas, includes ranges like the Dhauladhar and Pir Panjal. This region features lower peaks, forested slopes, and hill stations like Shimla and Mussoorie.
Shiwalik: The southernmost division of the Himalayas, the Shiwalik range is also called the Outer Himalayas. It consists of foothills, with lower elevations and less rugged terrain compared to the higher ranges. The Shiwalik region serves as a transition zone between the Himalayas and the plains.
(iii) The plateau that lies between the Aravali and the Vindhyan ranges is known as the Malwa Plateau. This plateau is a part of the larger Peninsular Plateau of India and is located in the central region of the country. The Malwa Plateau is characterized by its flat terrain, fertile soil, and agricultural productivity. It serves as an important agricultural region in India, known for the cultivation of crops like wheat, soybeans, and cotton.
(iv) The island group of India having coral origin is the Lakshadweep Islands. These islands are located in the Arabian Sea, close to the Malabar coast of Kerala. The Lakshadweep Islands are composed of small coral islands and atolls. They were previously known as Laccadive, Minicoy, and Amindive islands before being collectively named as Lakshadweep in 1973. These islands cover a small area of 32 sq km and are known for their diverse flora and fauna, as well as their pristine coral reefs.
3. Distinguish between
(i) Bhangar and Khadar
(ii) Western Ghats and Eastern Ghats
(i) Bhangar and Khadar are two terms used to describe different types of alluvial deposits found in the Northern Plains of India. The distinction between Bhangar and Khadar are:
Bhangar:
- Formation: Bhangar is the older alluvium that lies above the floodplains of rivers in the Northern Plains. It is formed by the deposition of coarser sediments over a long period.
- Location: Bhangar is located at a higher elevation compared to the floodplains and presents a terrace-like feature.
- Characteristics: The soil in the Bhangar region contains calcareous deposits known as kankar, which can make the soil less fertile.
- Age: Bhangar deposits are older and have undergone weathering and leaching processes over time.
Khadar:
- Formation: Khadar is the newer, younger alluvium deposited by rivers almost every year during the monsoon season. It consists of fine silt and clay particles.
- Location: Khadar deposits are found in the floodplains of rivers and are renewed annually by fresh sediments brought by river flooding.
- Characteristics: Khadar soil is fertile and rich in nutrients due to the regular deposition of fresh alluvial sediments.
- Agricultural Importance: Khadar lands are highly suitable for intensive agriculture due to their fertility and moisture-retaining properties.
In summary, Bhangar refers to the older, elevated alluvial deposits with calcareous content, while Khadar denotes the younger, fertile alluvial deposits found in the floodplains of rivers in the Northern Plains of India.
(ii) The Western Ghats and Eastern Ghats are two prominent mountain ranges in India with distinct characteristics. The differentiation between the two Ghats are as follows:
Western Ghats:
- Location: The Western Ghats run parallel to the western coast of India, stretching from Gujarat to Kerala. They are closer to the Arabian Sea.
- Elevation: The Western Ghats are higher in elevation compared to the Eastern Ghats, with peaks reaching up to 2,695 meters (Anai Mudi).
- Rainfall: These mountains intercept the moisture-laden winds from the Arabian Sea, causing orographic rainfall on the western slopes. This results in lush greenery and dense forests.
- Biodiversity: The Western Ghats are known for their rich biodiversity and are recognized as a UNESCO World Heritage Site. They are home to numerous endemic species of flora and fauna.
- Continuous Range: The Western Ghats form a continuous mountain range with fewer gaps or interruptions along their length.
Eastern Ghats:
- Location: The Eastern Ghats run parallel to the eastern coast of India, from Odisha to Tamil Nadu. They are located closer to the Bay of Bengal.
- Elevation: The Eastern Ghats are lower in elevation compared to the Western Ghats, with peaks reaching up to 1,501 meters (Mahendragiri).
- Discontinuous Range: The Eastern Ghats are discontinuous and fragmented by rivers draining into the Bay of Bengal. They have a more irregular and dissected topography.
- Rainfall: The Eastern Ghats do not receive as much rainfall as the Western Ghats. They do not cause as much orographic rainfall and are relatively drier.
- Cultural Significance: The Eastern Ghats have historical and cultural significance, with ancient temples and heritage sites located in the region.
In summary, the Western Ghats are higher, receive more rainfall, and have a continuous range along the western coast, while the Eastern Ghats are lower in elevation, receive less rainfall, and are discontinuous with a more irregular topography along the eastern coast of India.

Chapter 3 : Drainage
The chapter on drainage in the geography textbook delves into the intricate network of rivers in India and their significance. It begins by explaining the concept of drainage systems, where small streams merge to form main rivers that eventually flow into larger water bodies. The area drained by a single river system is termed a drainage basin, with elevated regions acting as water divides separating different basins.
The chapter extensively covers the major Himalayan rivers – the Indus, Ganga, and Brahmaputra. The Indus River originates in Tibet near Lake Mansarowar, flowing west into India through Ladakh and forming a picturesque gorge. It is joined by tributaries like Zaskar, Nubra, Shyok, and Hunza in the Kashmir region before passing through Baltistan and Gilgit. The Indus is further fed by the Satluj, Beas, Ravi, Chenab, and Jhelum rivers near Mithankot in Pakistan.
The Ganga river system is a focal point, with details on its bifurcation at the northernmost point of the delta. The Bhagirathi-Hooghly distributary flows southwards through the deltaic plains to the Bay of Bengal, while the mainstream continues into Bangladesh, merging with the Brahmaputra to form the Meghna. The Sundarban Delta, named after the Sundari tree, is the world’s largest and fastest-growing delta, home to the Royal Bengal tiger.
The chapter also touches upon the Krishna river basin and the National River Conservation Plan (NRCP) aimed at improving water quality in major rivers. Economic benefits of rivers and lakes are discussed, emphasizing their role in regulating river flow, preventing flooding, and supporting hydel power generation. The chapter includes exercises on identifying rivers and lakes on maps, categorizing lakes as natural or human-made, comparing Himalayan and Peninsular rivers, and discussing the economic importance of rivers for the country.
Overall, the chapter provides a comprehensive overview of the drainage systems in India, highlighting the significance of rivers and lakes in shaping the landscape, supporting ecosystems, and contributing to the economy.
