Answer:
Northern Great Plains situated between Northern mountain system and Peninsular plateau play a decisive role in the economic development of India. Northern Great Plains is formed due to the continuous depositional activity of the Himalayan rivers. With several thousand kilometers of thickness, these plains spread to about 7 lakh km². This plain is one of the world’s most extensive alluvial plains. The plains are also known as Indo- Gangetic-Brahmaputra plain.

Alluvial soils are the major type of soil in there plains. There soils are highly fertile. So there plains are called the backbone of Indian agriculture. The Northern Plains are also known as the granary of India. Major crops cultivated here are wheat, maize, paddy, sugarcane, cotton and pulses. Fertile soils, flat land and the availability of waterthroughout the year attract people to these plains. So it is the most densely populates region in India. A variety of food crops and cash crops which add to the economic prosperity of India are produced here.

Along with agriculture, many agro-based industries and mineral-based industries are located here. The growth of industries paved the way for the emergence of many cities. The major Indian cities are located in these plains. The plains have well-connected road and railway network which help to transport goods to different parts of the country. The Great Plains are the birthplace of Indian culture. Many Hindu pilgrim centers are located here. Thus the Great Plains help in the cultural life of India also.

In India like physiography climate also is diverse. Latitude, physiography nearness to ocean and attitude are the factors influencing the climate of India. In India seasons can be generally classified into winter season December, January, February. Summer: March, April, May, June, Southwest monsoon season June, July, August, September, Northeast monsoon season October, November, Summer, and winter is severe in north India. In peninsular India there is not much difference in the summer and winter temperature. Southwest monsoon brings plenty of rainfall to the western coast of India, whereas the coromandel coast receives rain from the northeast monsoon.

Question 31.
Which are the winter months in India?
Answer:
December, January, February

Question 32.
Coastal regions experience comparatively high temperatures. why?
Answer:
Water has a higher heat capacity than soil and rock. So the ocean takes much longer to heat and to cool than the land.

Question 33.
Which are the months of southwest monsoon season in India?
Answer:
June, July, August, September

Question 34.
Rainfall is comparatively less along the eastern slopes of the western ghats, why?

The eastern slope of the western ghats lies to the law and side of the southwest monsoon. So this region has become a rain shadow region.

Question 35.
By what name is the southwest monsoon rain known in Kerala?
Answer:
‘Idavapathi’

Question 36.
What is the role of eastern high lands in the heavy rainfall in the northeastern states?
Answer:
The Bay of Bengal branch of the southwest Mon¬soon advances northward by absorbing more mois¬ture from the Bay of Bengal. Again it bifurcates and one branch
which turns towards northeastern states is blocked by the eastern highlands bringing plenty of rainfall.

Question 37.
‘What causes the rightward deflection of these winds?
Answer:
In the northern home, sphere winds deflect towards right due to the conolis effect and the southward movement of the sun.

Question 38.

Question 40.
What is western disturbance? Write its benefit.
Answer:
During the cold-weather season of India, low pres¬sure systems develop over the Mediterranean sea and travel towards east under the influence of jet streams and enter India. This causes winter rainfall in North plains, especially in Punjab. This is known as western disturbance. This is most suitable for the cultivation of rabi crops like wheat and barley.

Question 41.
Explain ‘October heat’.
Answer:
The northeast monsoon season experienced in the months of October and November is an interval between rainy season and cold weather season. The high temperature and humidity experienced all over India during this time make the day time very un-comfortable or sultry. This phenomenon is called October heat.

Question 42.
Though northeast monsoon winds are dry, they cause heavy rainfall over the Coromandel coast of India. How?
Answer:
During the northeast monsoon period, low pressure areas are formed over the Bay of Bengal and attract air from land. The monsoon winds which blow from land to ocean get moisture from the Bay of Bengal and move in south-east direction. These winds cause heavy rainfall over the Coromandel coast.

Question 43.
Which are the different types of soil found in India?
Answer:

Alluvial soil
Black soil

Desert soil
Mountain soil

Answer:

A	B
Brahmaputra	Chemavunduna
Indus	Himachal Pradesh
Trans Himalayas	Mount K2
Purvachal	Khasi

Question 47.
Regions close to oceans experience high temperatures during winter season. Why?
Answer:
Land gets heated up and cools quickly than ocean. Land experiences high pressure during winter season and ocean low pressure. The dense air from regions lying close to ocean move to less dense air area of ocean. This reduces the cold of those places.

Question 48.
During southwest monsoon period, less rainfall is experienced on the east of Western Ghats. Why?
Answer:
The Western ghats obstruct the rain-bearing Arabian sea branch of southwest monsoon winds and cause heavy rainfall on the western margins in the state of Kerala, Karnataka, Goa, and Maharashtra. But the east of Western Ghats receives only less rainfall. This is because by the time the monsoon winds cross the Western Ghats and reach the east, the moisture content in them will be lost. This is the reason why Tamil Nadu gets scanty rainfall during southwest monsoon period while Kerala receives heavy rainfall. The eastern part of Western Ghats is a rain shadow region.

Question 49.
What are the reasons for regional distribution of rainfall in India?
Answer:

Physiography
Location of mountain ranges
Nearness to oceans
Distance from oceans
Direction of wind.
Extent of land

Question 50.

Question 54.
Which are the two branches of southwest monsoon winds? Identify the regions where they cause rainfall.
Answer:
Due to the peculiar shape of the Indian peninsula, the southwest monsoon winds enter India by bifurcating into two branches -Arabian Sea branch and Bay of Bengal branch.

Arabian Sea Branch:
The Arabian sea branch which reaches Kerala coast by the beginning of June gives heavy rainfall in the western parts of Kerala, Karnataka, Goa, and Maharashtra.

Bay of Bengal branch:
The Bay of Bengal branch which absorbs moisture from Bay of Bengal advances through Sundarban delta and enters West Bengal and bifurcates into two. One branch enters the Brahmaputra plains and gives heavy rainfall in the northeastern states. Khasi, Garo hills obstruct the winds to cause rainfall.

The other branch enters the Ganga plains and gives rainfall in the states of West Bengal, Bihar, and Utter Pradesh. This branch joins with the Arabian Sea branch in the Punjab plain, moves northward and gives heavy rainfall in the foothills of the Himalayas.
