mountains which have been thrown up into a Massive Fold or ridge by horizontal earth movements. Often the mountains form an Anticline, and troughs are Syuclines.) The folding was due to the cooling and contraction of i Che earth, so that the crust, already cold and shrunken håd to wrinkle to fit itself to the still cooling and, contracting "core".

The continental drift theory was suggested by the German Alfred Wegener. Before the "dimalaya's earth- stora" occurred, there were two separated blocks of continental masses. The Indo-gangetic trough separated the Tibetan Plateau in the North and the Deccan Plateau in the South. Great volume of sediments were trans- ported by rivers into this trough. For some reason or other, the land on either side, or one side, of a sea began to move, and the sediments that have been depo sited beneath the sea (the trough) several miles deep, were thrown up into great folds in which many cracks or faults appeared. Sometimes the layers would be piled up on each other; sometimes they would crack inte great blocks which slipped along on top of each other. As the result of pressure from the south (the Deccan) the weaker part of the trough (the Indo-Gangetic: Plain) was micked up into gigantic folds and troughs against the resistant north barrier (the Tibetan Plateau). As these folds had continued to buckle, finally the rocks in the middle of the folds were worn away and the fold mountains of Himalaya were formed,

A Plain, bordering a river, has been formed by the gradual accumulation of silt brought down by rivers When a river rises and overflows it banks, the water spreads over the flood-plain; a layer of/ sediment is deposited at each flood, so that the flood plain gradually rises. It is usually highest near the river, at the natural løves. During the formation of a flood plain, it is often characterized\ by marshes, meander, and ox-bow lakes, If the drainage system is later diverted, the flood plain may be left as a smooth and extremely fertile tract of land, erg.

d) Chief towns and ports. Illustrate your answer with sketch maps..

The pear-shaped island of Ceylon and the long narrow island of Java have many features in common. a) Physical features: Both islands are mountainous. In Ceylon, the high mountains occupy the central part of the wider south leaving a broad lowland in the north. In Java, the discontinous young fold mountains running from east to west lie close to the south leav- ing a wider coastal plain in the north.

In Java, there is the frequent volcanio activities resulting in, the presence of fertile agricultural soil. This helps to account for the fact that Java, though with less amount of lowland, has a larger population than Ceylon The volcanoes in Jaya, many of which are active, form a belt just to the north of the fold moun tains.

However auch volcanic activities are absent. in Ceylon which is mainly composed of crystalline rocks The rivers of the two islands are short and rapid. In Ceylon they form a marked radial pattem.

ERARIES!

Apart from the monsoons, much of the rain that falle in Ceylon and Jaya is convectional. In addition, tropical cyclones in October and November add more rain to Ceylon especially its east coast but not to Java which lies outside the typhoon tracks.

• Thus in Ceylon and Vava, rainfall is heavy but

is unevenly distributed. In Ceylon, rainfall decreases from the south-west to the south-easter tip and the north-west

while in Java, rainfall decreases from the. west to the east. The difference between the rantall of the wettest andirlest areas often exceeds 80",

e) Crops grown: Since both of them lie within the crp-? pics, crops grown are mainly tropical crops. Among the food crops grown, rice is the chief crop, which occupies a large part of the lowlands. In drier central and eastern Java, maize ranks as an important crop along with rice.

Owing to the important location of Ceylon and Java in international trade routes and the presence of heavy rainfall and high temperatures, cash crops

crops are largely. grown on plantations, Each crop is largely localized in those areas which are particularly suited to it, in Ceylon, plantations are largely located in the south west Coconuts, rubber and tea are the main export crops. Other crops grown are cacao, tobacco, cinnamon and citronella. In Java, the wide variety of physical and elimatic environments has encouraged the cultivation of a wide variety of plantation crops, the most important ones being rubber, tea, coffee and sugar cane. Other crops grown include coconuta, cacao, tobacco, 011 palm, sinchona and kapok.

d) Chief towns and porvEL, LOB COLDI Lown of Gey Lon: 19 Colombo with a population of about 500,0

at the sheltered by an artificial harbour, It is a great entrepot port. It is at the meeting point of several\ important sea routes. It is also the road and railway centre. The other important towns include Jaffna, thej second largest town in Ceylon, Trincomalee, a port on the east coast, and Galle, a port situated south of Colombo

The onics and the largest town or Java 18 Jakarta the capital of Indonesia. It has a much larger popule- tion than Colombo, about three millions. Unlike Colombo, it, is not an important, port though originally it was an important port at the mouth of the Jjilwung but the old harbour has now been silted up. An outport has been. built at Tanjong Priok, about six miles to the north- east of Jakarta, which handles most of the exports of - Java - Jakarta is the focus of the railway system and it has an international airport. The other important towns are Surabaye, the second part of Java, t the Indonesian eminus of international shipping routes and a major naval base, and Semarang, the port for central Java and} also a marketing centre.
