11. Write down the characteristics of the climate of India.
Answer: The characteristics of the climate of India are:
1. Seasons: The climate of India is influenced by the two oppositely blowing monsoon winds, i.e The south-west monsoon winds help in the classification of Indian climate into four seasons-Winter (December-February), Summer (March-May), Monsoon or Rainy season (June-September) and Autumn (October-November).
2. Oppositely blowing winds: The direction from which the winds blow in the summer season (south-west) is reversed in the winter season (north-east).
3. Hot wet summers and cool dry winters: The moist south-west monsoon winds provide sufficient rainfall during late summer and the rainy season. The north-west monsoon winds are generally dry and do not provide rainfall except for the
Coromandel coast of Tamil Nadu. Thus, the summers are hot and wet while the winters are cool and dry.
4. Orographic rainfall: The south-west monsoon winds collide with the mighty Himalayas on the north and the Western Ghats along the western coast. Thus, they provide orographic rainfall in the foothills of the Himalayas and the western slopes of the Western Ghats.
5. Unpredictable rainfall: The whimsical nature of the monsoon winds make the occurrence of rainfall unpredictable. In some years rains come early and retreats late, while in some years the rains arrive late and retreats early. Thus, the monsoon winds sometimes cause floods and sometimes lead to droughts.
6. Diverse climate: The northern part of India is surrounded by landmasses. Hence, it experiences extreme and continental climate. The southern part is surrounded by oceans on three sides (west, south and east). Hence, it experiences moderate climate.
7. Cyclones: During the autumn season, the eastern and the western coastal regions experience cyclonic storms and rainfall. During the winter season, the Western disturbances cause cyclonic rainfall in the north-western part of India. The temperature drops to a great extent, and the hilly regions experience snowfall.
12. Write a note on the impact of monsoons in India.
Answer: The impact of monsoons on Indian climate is significant. Monsoons blow in different seasons of the year, especially during summer and winter. In summer the south-west monsoons blow and in winter the north-east monsoons blow.
(i) South-west monsoons: The south-west monsoons enter India after blowing over he Arabian sea. As this wind comes from the south-western side, it is called
south-west monsoons. This wind carries enormous amount of moisture from the Arabian sea and hits the western Ghats. Then it rises up and on getting cold rain occurs. In this way, the western coasts such as the Konkan and the Malabar coasts receive more than 300 cm of rainfall annually. This wind then crosses the Meghalaya plateau and enters into Assam. It then moves further north and gets obstructed by the foothills of the Himalayas. In this way, Assam and the foothills of Himalayas also receive heavy rainfall due to the south-west monsoons during summer.
(ii) The North-East monsoons: The north-east monsoons, on the other hand blow during winter. This cold wind flows from the central Asia and enters India from north-east direction. This is why, it is called the north-east monsoon. The monsoon. The northern Himalayas mountains stand as a barrier to this cold wind, and so northern India is not affected by severe coldness due to this wind. However, a portion of this wind comes across the Himalayas and enters into India. As it comes
from the land areas of central Asia, it is dry and it cannot produce rainfall, But, when
this wind flows over the Bay of Bengal, it carries some amount of moisture. This moisture-carrying wind then gets obstructed with the Eastern Ghats and thus rainfall takes place on the east coast, especially along the Coromandel coast.
13. Outline the pattern of rainfall distribution in India.
Answer: The pattern of rainfall distribution in India varies significantly across different regions. Some key points include:
1. Heavy Rainfall: The areas with the highest rainfall, exceeding 300 cm annually, are found along the foothills of the Himalayas, the northeastern regions, the southern parts of the Meghalaya plateau, and the western slopes of the Western Ghats. The highest rainfall occurs in Arunachal Pradesh, where the average annual rainfall exceeds 400 cm.
2. Low Rainfall: In contrast, the Thar Desert and its neighboring areas receive very little rainfall, often less than 50 cm annually. Some parts of the desert even get less than 20 cm of rainfall. Similarly, areas in the northern and western Deccan plateau, including Gujarat, experience between 50 cm and 100 cm of rainfall annually.
3. Medium Rainfall: The northern plains of India, including the Brahmaputra plain, receive a moderate amount of rainfall, ranging between 100 cm and 200 cm annually.
4. Monsoon Influence: The monsoon season significantly impacts Indian agriculture, with the southwest monsoons being more important for rainfall than the northeast monsoons. The southwest monsoon brings heavy rainfall that is crucial for crop production.
Overall, rainfall is unevenly distributed across India, with the western and northern parts being drier compared to the northeastern and coastal regions.
14. Write about the types of the vegetations of India.
Answer: Natural vegetation denotes the plant community, which grows naturally without the help of human beings and has been left undisturbed, away from humans for a long time. Cultivated crops and fruits form a part of the vegetation but are not referred to as natural vegetation.
There are different types of climate in different physiographic environments over the surface of the earth. Such differences in climate cause variations in soil types. Again different soil types support different types of vegetations. So, it can be said that the types of vegetations, their growth and distribution mainly depend on climate, physiography and soil.
Types of physiography, elemate and soils differ from place to place in India. So also the types and distribution of vegetations vary within the country.
The vegetations of the country can be broadly classified into six types:
(i) Evergreen vegetations, (ii) Monsoonal vegetations, (iii) Dry thorny vegetations, (iv) Grassland vegetations, (v) Mangrove vegetations, (vi) Mountain vegetation.
15. What are the different types of migration?
Answer: Migration is the movement of people from one place to another, and it is frequently linked to a change of permanent residence.
The different types of migration are:
(i) Internal migration, (ii) International or external migration.
Again, Internal migration are two types: (i) Inter state migration, (ii) Intra state migration.
16. What are the impacts of migration in India?
Answer: The impacts of migration of India are:
(i) Due to migration, variations in communities, religions and languages are increasing and, as a result colourful cultures have grown,
(ii) Changes in the economic sector and expansion of trade and commerce are caused due to migration.
(iii) Migration has changed the demographic structure of the country as well as its different regions. Population growth, density and literacy rates are changing due to migration. In some regions of the country, the numbers of migrants have become more than the numbers of indigenous people, and as a result some problems related to language, religion, culture and economy have emerged.
(iv) Migration contributes directly to the growth of India’s population. A number of problems have arised due to migration. Population pressure on land is increasing and forest and wetland ecosystems are affected. Moreover, problems have arised in the health and education sectors in addition to the problems of employment.
(vi) Due to migration, sometimes some serious religious, social and political problems may take place.
(vi) Migrants sometimes suffer from mental pressure as they fail to adjust with the new places as well as new societies.
(vii) Slums generally grow, especially in the urban areas due to migration. The slum areas with unhygienic conditions cause pollution to the urban environment.
(viii) Due to migration, the political situations of the country or the states are on the way to change.
17. Write down the main features of Indian economy.
Answer: The main features of Indian economy are:
(i) Low per capita income, (ii) Slow growth of per capita income, (iii) Excessive pressure of population, (iv) Poverty, (v) Dependence on agriculture, (vi) Growing unemployment problem, (vii) Planning based development.
