Question 1.
What do you mean by drainage system? Write a note on it.
Answer:

A drainage system is an integrated system of tributaries and trunk stream which collects and drains surface water into the sea, lake or some other water body.
The total area drained by a river and its tributaries is known as a drainage basin.
The drainage pattern of an area is the result of the geological structure of the respective areas.
The river system provides irrigation, drinking water, power generation and livelihood for a large number of population.
The drainage system of India is broadly divided into two major groups on the basis of their location. They are
- The Himalayan rivers
- Peninsular rivers

Question 2.
“Unity in Diversity”. Explain.
Answer:
India is a vast country with a diversity of Physical characteristics.

Diversity in Natural Phenomena

India has unique landforms ranging from the highest peaks to the lowest plains. In the north India, Mount Godwin Austin, otherwise known as Mt. K2 is the highest peak of India and coastal plains are the lowest in the South India.
The Climate varies from the tropical to the temperate zone. Mawsynram in Meghalaya receives the highest amount of rainfall whereas the thar desert receives very low rainfall.
We have wet dense tropical forest on the western Ghats, Mangrove trees in the sundarbans of West Bengal and the shrubs and sparse vegetation in the Thar desert.
The diversity of the physical environment and climate has made India an ideal habitat for varieties of flora and fauna.

Diversity in Natural Phenomena
India is a secular country with total freedom of worship. People follow Hinduism, Christianity, Islam, Sikkism, Buddhism, Jainism and Zoroastrianism with cultural diversities.

Unity in Diversity
Inspite of its physical, religion and racial varities, the ‘Indian Culture’ unites all people. Hence India is known for her “Unity in diversity”.

People shed all their differences and stand together when is a crisis. The best examples are kargil invasions and natural calamities like floods and Tsunami. Even if we differ in many factors, we are all one in the fact we are Indians.

Question 3.
Give an account on Punjab-Haryana plains.
Answer:

Punjab Haryana plains are one among the subdivisions of the Northern plains.
They are formed by the deposition of the rivers Sutlej, Beas and Ravi, the tributaries of River Indus.
They lie to the North-east of the Great Indian Desert.
These plains are found over an area of about 1.75 lakh sq.km.
These plains act as water-divide (Doab) to the rivers Yamuna-Sutlej and Ganga-Yamuna.

Question 4.
Explain the origin of the Himalayas.
Answer:

Millions of years ago there was only one landmass on the surface of the earth. It was surrounded by ocean on all sides.
The landmass was called “ Pangea”. It was surrounded by a waterbody Known as “Panthalasa”.
This large landmass split up into two parts. The northern part was known as “Angaraland” and the southern part was known as “Gondwana land”.
The Sea seperating these two was called the Tethys Sea.
This Sea stretched along an east-west direction.
The rivers from Angara and Gondwana deposited the silts along the Tethys Sea.
After a long period, due to tectonic forces the deposits up lifted to forms fold mountains called the Himalayan range.
It is an young fold mountain.
The Himalayas is the home of several high peak. However, it holds the record of having the maximum number of highest peaks among any mountains range in world. Out of the heights peaks in this world, Himalayas holds nine.

Question 5.
Give an account of the four divisions of Himalayas from west to east along with Purvanchal hills respectively.
Answer:
Divisions of the Himalayas of the basis of regions from west to east. These division have been demarcated by river valleys.

(i) Punjab Himalayas:
The part of the Himalayas lying between Indus and Sutlej has been traditionally known as Punjab Himalayas but it is also known as regionally as Kashmir and Himachal Himalaya from west to east respectively.

(ii) Kumaon Himalayas:
The part of the Himalayas lying between Satluj and Kali rivers is known as Kumaun Himalayas.

(iii) Assam Himalayas:
The Kali and Tista rivers demarcate the Nepal Himalayas and the past lying between Tista and Dihang rivers is known as Assam Himalayas.

Purvachal:

The Brahmaputra marks the eastern most boundary of the Himalayas. Beyond the Dihang gorge, the Himalayas bend sharply to the south and spread along the eastern boundary of India. They are known as Purvanchal or the Eastern hills and mountains.
These hills running through the north-eastern states are mostly composed of strong sandstones which are sedimentary rocks.
It covered with dense forests, they mostly runs as parallel ranges and valleys.
The Purvanchal comprises the Patkai hills, the Naga hills, Manipur hills and the Mizo hills.

Question 6.
Give a detailed account on the Great Northern Plains.
Answer:
Formation:
The Northern Plain has been formed by the interplay of the three major river systems namely – The Indus, The Ganga, and The Brahmaputra along with their tributaries. This plain is formed of alluvial soil. The deposition of alluvium in a vast basis lying of the foothills of the Himalayas over millions of years formed this fertile plain.

Extension:

It spread over an area of 7 lakh sq.km. The plain being about 2400 km long and 240 to 320 km broad, is a densely populated physiographic division.
Importance:
With a rich soil caves combined with adequate water supply and favourable climate it is agriculturally a very production past of India.

Important Features:

In the lower course, due to gentle slope, the velocity of the river decreases which results in the formation of riverine islands. Majuli, in the Brahmaputra River is the largest inhabited riverine island in the world.
The rivers in their lower course split into numerous channels due to the deposition of silt. These channels are known as tributaries.
The Northern Plain is broadly divided into three sections. Punjab plains, Ganga plains and Brahmaputra plains.
According to the variations in relief features, the Northern plains can be divided into four regions – Bhabar, Terai, Bhangar and Khadar.

Punjab Plains:
The Western part of the Northern plain is referred to as the Punjab plains formed by the Indus and its tributaries. The larger part of this plain lies in Pakistan Indus and its tributaries – The Jhelum, the Chenab, the Ravi, the Beas and the Satluj originate in the Himalayas. This section of the plain is dominated by the doabs.

Ganga Plains:
They extend between Ghagger and Teesta rivers. It is spread over the states of North India like Haryana, Delhi, U.P., Bihar, Partly Jharkhand and West Bengal.

Brahmaputra plains:
In the east of Ganga plains lies the Brahmaputra plains. They cover the areas of Assam and Arunachal Pradesh.
According to the variations in relief features, the Northern plains can be divided into four regions.

Bhabar:
The rivers after descending from the mountains deposit pebbles in a narrow belt of about 8 to 16 km in width lying parallel to the slopes of the Shivaliks. It is known as Bhabar. All the streams disappear in this Bhabar belt.

Terai:
South of this belt, the streams and rivers re-emerge and create a wet swampy and marshy region known as ‘Terai’. This was a thickly forested region full of wildlife.

The Terai is wider in the eastern parts of the Great plains, especially in Brahmaputra valley due to heavy rainfall. In many states, the Terai forest have been cleaned for cultivation.

Khadar:
The newer younger deposits of the flood plains are called Khadar. They are renamed almost every year and so are fertile. Thus ideal for intensive agriculture. The Khadar tracts are enriched by fresh deposits of silt every year during rainy seasons. The Khadar land consists of sand, silt, clay and mud. It is highly fertile soil.

Delta Plains:
The deitaic plains is an extension of the Khadar land. It covers about 1.9 sq.km in the lower reaches of the Ganga River. It is an area of deposition as the river flows in this tract sluggishly. The deltaic plain consists mainly of old mud, new mud and marsh. In the delta region, the uplands are called “chars”. While the marshy areas are called ‘Bils’
