Young Fold Mountains\
These mountains were formed in the Alpine period (about 40 million years ago).
righ mountains, usually over 10,000 Fees high, stretch out from two mountain knots the Armenian not in Western and the Pamir knot in Gentral Asia.
From the Armenian Knot two mountain ranges extend into Asia Minor: the Pontic in the north and the Taurus in the south,
From the Pamir, knot two mountain ranges. run eastwards - the Kunlun in the north and the simplayas in the south. Stretching westwards from this khat is Hindu Kush, the extension of which; the Caucasus, lies. between the Black Sea and the Caspian Sea. between the two knots are the Elburz. the north and the cagros and the Sulaiman farizes in the southé
Intermontane Plateaux or Basin
These plateaux lie between high mountains For example, the (1) libetan Plateau (between Kunlun and Himalayas (11) the Persian Pisteau (between Hindu Kush and. Zagros and sulaiman), (111) the Anatolian Plateau (between Pontic and Taurus). AD example of intermont basin is the Tarim Basın Firing between the Tien Shan and the Kunlun.

In late spring when ice, in thei upper courses melts, their courses are still frozen, therefore there are no outlets for the meitung ice, As a result, extensive flooding Lakes place in their lower courses. In addition, these rivers are far away from the populated and commercial areas, thus they are seldom utilized though they offer great potentials for H.E.P
Descripe now the cries factors affect the climate
As la..
Ans. The chief factors affecting the climate of Asia
are
Continentality.
Owing to the huge size of the continent," most parts of the interfor are very far away from the ses 49, a land surface absorbs and gives out her more quickly than a water surface) it is the different rates of heating and cooling! of the land and the sea in summer end that results in the formation of the monsoons in Asia
winter
In winter, because the rapid radiation and the great distance from the sea, the interior becomes extremely cold. The air becomes very dense and high pressure developa over the Mongolian Desert. Throughout the season, air from the upper atmosphere is descending. Thus air is pressed outwards from the high pressure centre. So there is a general movement of wind From the interior towards the ocean, where pressure is relatively lower. This is the winter monsoon, utblowing cr offshore winds do not bring much rain since they have very little opportunity for picking up moisture, except on their way to Japan, South-east A319, Ceylon and South india,
Iri summer because of the rapid nesting of the land and the great distance from the sea, eir over the continent becomes very hot, expands and rises. The interior experiences high temperatures. An area of low pressure is formed extending over the whole of the continent with the lowest pressure in Punjab. This causes an inflow of air from the surrounding srea of nigher pressure 1.e. from the sea. This is the summer monsoon. The onshore or inglowing winds are warm end hoist, thus they bring rain, sometimes very heavy, rain to most parts of the continentsy
This seasonal change or wind and rain produces what is generally called a seagal or monsoonal climate. The interior of the continent, while having large seasonal range of temperature has continental climate, Relief Barriers
f
There are high mountain ranges extend ing throughout the width of the continent. Together with the effect of the great distance from the sea, large areas of the interior of Maia, have very low rainfall, For example, the Himalayas 19 an effective climatic barrier. In summer, it causes heavy rainfall on its southern slopes and keeps Tibet dry. In winter, it prevents the cold air from entering Ladia. As a result, winter temperatures at Calcutta ire consideraciy] higher than that at Hong Kong though the two places
are located not far apart in terms of Ratitude. Similarly, the Isinling fange divides China into a cool, dry north, and a warm, moist south,
These relier barriers are 6190 the cause, or uneven distribution of rainfall, even within thei
In winter the Mediterranean Sea nas grasler effect because Atlantic depressions, taking more southerly routes may pass right across the mediterranean Sea and bring rain to an area extending from Anatolia, Syria, Israel to Caspian Sea..
Ocean Currents
Ocean currents exercise influence upon the climate of a coastal area by first warring or cooling the winds that blow over it. Therefore, they are effective modifiers only when the winds are on-shore. For example, the warm Kuro Shio currant which arrives at the Japanese coasts from the south does not raise the winter temperature of eastern Japan though it has a Blight warming effect on the western coast whe the N.W. mong Jon winds are on-shore, The warming effect of the Kuro Shio is is, however, felt in summer, when the S.E monsoon winds are on-shore
This enables the prevailing winds to pick up moisture more easily and in turn gives heavy rain to the south-eastern part of Japan." Similarly, the cold Okhotsk current lower the temperature of the air mass passing over it and consequently lowers the temperature at the coasts) of Hokkaido.
Typhoons
They occur in the Pacific sast or the Philippines mainly between July ani Uctober. affect the climate of the Philippines, south China, Vietnam and sometimes Japan, bring heavy, rainfall and perhaps cause damages,
