F. Answer the following questions in detail.
Describe the Northern Lowlands of Asia.
The Northern Lowlands of Asia extend from the Ural Mountains in the west up to the Bering Strait in the north-east. These lowlands are triangular in shape and widest in the west. Lying between the Arctic Ocean in the north and the Central Mountains in the south,they form the world’s greatest continuous plains. Three rivers which flow northwards into the Arctic Ocean — Ob, Yenisei and Lena, have together built this plain. These marshy and swampy lowlands are also called as the Great Siberian plain. The lower courses and mouths of the rivers freeze in winter. So, water coming from the upper courses in warmer latitudes spreads out over large part of the plains. Another low lying land exists south of the Siberian Plains in Central Asia called as the Turan Plain. This plain is an area of inland drainage and is drained by rivers Amu Darya and Syr Darya.
Write about the Mediterranean climate experienced in Asia.
The Mediterranean Climate in Asia is characterized by warm, dry summers and cool, wet winters.
Since these areas experience drought-like conditions in summer, the natural vegetation has adapted to the climate by developing long roots and spongy barks. The evergreen vegetation of oak, acacia, laurel, chestnut, walnut and olive trees is common. Orchards of citrus fruits such as lemons, and oranges, vineyards and farm grains have replaced the natural vegetation. In the absence of natural habitat, not much wildlife is found. Mostly domesticated animals such as donkeys, cattle and sheep are found.
Explain how the Himalayas have greatly influenced the life of the people of India.
The Himalayas exert a significant influence on the life of the people of India in several ways.
- They form a natural boundary between India and China.
- They serve as a climatic barrier by preventing the entry of the cold winds from Central Asia and preventing the rain-bearing monsoon winds from leaving India.
- They are a source of perennial rivers such as the Indus, the Ganga, and the Brahmaputra and their tributaries.
- Their rugged terrain is ideal for hydroelectric power generation.
- The mountain slopes are forested. These forests provide different types of timber and forest products.
- The Himalayas have beautiful hill Stations Shimla, Daijeeling, Mussorie, etc.
Why is south India warmer than north India?
Because it is nearer to the equator.
Explain the importance of monsoon.
A good monsoon is important for the entire country for these reasons :
- A good monsoon brings economic prosperity for the whole country and boosts the Indian economy as agriculture contributes around 16 per cent of its total Gross domestic product (GDP).
- High temperature and heavy rainfall in the summer months are important for different types fo kharif crops. The winter rain supplemented by irrigation is important for rabi crops.
- A normal rainfall is important for adequate agricultural production in order to maintain food prices. Food prices depend upon the agricultural output. In the absence of a good monsoon, the entire nation may be destabilized because of food inflation.
- Several dams, reservoirs, rivers and canals in India are rain- fed and depend upon the monsoon rains.
- Other economic activities like forestry and fishing are also influenced directly by the amount of rainfall.
- Monsoon rain gives us respite from the high and intolerable summer heat and brings back life to the living earth.
- Monsoon also has a role to play in the social-cultural unity of India. People of India, particularly the farmers, eagerly wait for the monsoon rains. We know that the monsoon winds provide water for the various agricultural activities. The agricultural calendar, and the social-cultural life of the people including their festivities, revolve around the monsoon phenomena and in a way binds the people of India together. Different harvest festivals in our country such as Bihu in Assam, Pongal in Tamil Nadu, Onam in Kerala and Lohri in Punjab are celebrated to mark a good harvest. If the rainfall is good, the entire country celebrates and if the monsoon fails, it brings famines and a year of sorrow for everyone.
